Abstract
ABSTRACT Electroconvulsive therapy (ECT) is considered an effective therapy for patients suffering from severe, life-threatening, intractable depression. This treatment modality delivers controlled electrical currents (typically no more than 100 J) under general anesthesia to induce seizure. Although generally considered to have a high safety profile, physiological changes induced during the ictal phase of ECT, such as elevation in blood pressure and intracranial pressure, impose additional risks to patients with concomitant cardiovascular or cerebrovascular conditions. We describe the successful use of ECT in a unique case complicated by a combination of acute vertebral artery dissection, traumatic intracerebral hemorrhage, and cervical spine injury sustained from a suicide attempt by intentional motor vehicle collision. Although ECT can be safely administered in the presence of recent vertebral artery dissection and traumatic intraparenchymal hemorrhage, an emphasis on multispecialty coordination is crucial to monitor and reduce the risk of elevated blood pressure and further cervical spine injury.

Abstract
INTRODUCTION Theoretically, the procedural risk of electroconvulsive therapy (ECT) could be increased in the presence of undetected aneurysms due to the hemodynamic changes associated with ECT. However, empirical evidence is limited to few individual case reports and case series. METHODS We performed a systematic review of available evidence on ECT treatment in patients with intracranial aneurysms and untreated aortic aneurysms and we retrospectively analyzed data from 252 consecutive patients referred for ECT at the Department of Psychiatry, Psychotherapy and Psychosomatics of Siegen Hospital, Germany, who received magnetic resonance angiographies and abdominal sonographies as part of their routine pre-ECT workup. RESULTS Of 252 patients referred for ECT, 5 (2.0%) were found to have an intracerebral aneurysm and 1 (0.4%) was found to have an abdominal aortic aneurysm. These cases are reported in detail together with 2 additional cases of aortic aneurysms from the Central Institute of Mental Health, Mannheim, Germany. Electroconvulsive therapy was performed without complications in all 8 cases. CONCLUSIONS Aneurysms might occur in ECT patients at a similar rate as in the general population. The number of ECTs performed annually in mostly unscreened patients suggests that there might be a significant number of patients with undetected aneurysms in whom ECT is performed without reported complications.

Abstract
ABSTRACT Subarachnoid hemorrhage due to cerebral aneurysm rupture is a devastating event with a high mortality and significant morbidity. The safety of patients undergoing electroconvulsive therapy (ECT) in the presence of an aneurysm is not clear and is a cause of anxiety for both health care workers and patients. The present article collated the available evidence related to ECT in the presence of an aneurysm and found that there were no case reports where ECT directly led to the rupture of an aneurysm, although 1 case reported a rupture of an aneurysm between sessions of ECT. The epidemiology of cerebral aneurysms is discussed, as are key clinical considerations related to the care of patients with aneurysms who require ECT.

Abstract
ABSTRACT Electroconvulsive therapy (ECT) remains stigmatized in the broader medical community because of misunderstandings about treatment procedures, mortality rates, and cardiovascular complications. Electroconvulsive therapy causes periprocedural hemodynamic variability because of the surges in parasympathetic and sympathetic nervous systems after the administration of the electrical charge. Patients experience an increase in cardiac workload, which is potentially dangerous for patients with preexisting heart disease. Several findings suggest that cardiac complications occur most frequently in patients with underlying cardiovascular disease. We describe the cardiovascular complications that may result from ECT treatment and offer insight on how to mitigate these concerns if they occur. PubMed was queried using terms "electroconvulsive therapy" and "cardiovascular adverse effects." A table is provided with the common cardiovascular side effects of ECT and the most recent evidence-based treatment strategies to manage them. Generally, ECT is a safe procedure in which complications are minor and manageable. Most major complications caused by ECT are related to the cardiovascular system; however, with an appropriate pre-ECT evaluation and a comprehensive multidisciplinary team approach, the cardiovascular complications can be well managed and minimized. Providing proper cardiac clearance can prevent cardiac complications and provide timely care to treatment-resistant populations who are at risk for excessive morbidity and suicide.

Abstract
OBJECTIVES The aim of the study was to report a case of a patient who experienced a fatal aneurysmal subarachnoid hemorrhage during the course of electroconvulsive therapy (ECT). METHODS This is a case report and review of the literature. RESULTS Electroconvulsive therapy is widely viewed as a safe and effective treatment for major depressive disorder; however, there remains some uncertainty regarding the safety of ECT in patients with cerebral aneurysms. Many cases exist documenting the safety of ECT in patients with both secured and unsecured cerebral aneurysms; however, these patients had aneurysms that were associated with a low (ie, ≤2.6%) 5-year cumulative rupture rate, whereas the patient in our case had an aneurysm associated with a 14.5% five-year cumulative rupture rate. CONCLUSIONS We stress that ECT should not be viewed as a universally safe procedure in patients with cerebral aneurysms and the 5-year cumulative aneurysm rupture rate should be used in the discussion of the risk-benefit ratio of ECT in patients with unsecured cerebral aneurysms.

Abstract
Electroconvulsive therapy (ECT) is associated with at least transient episodes of hypertension and tachycardia. Beta-blocking agents may be indicated to prevent cardiovascular complications and may shorten seizure duration. This review evaluates studies that used beta-blocking agents during ECT to determine which agent has the most favourable outcomes on cardiovascular variables and seizure duration. A Medline database search was made using the combined keywords 'adrenergic beta-antagonists' and 'electroconvulsive therapy'. The search was restricted to double-blind randomized controlled trials and yielded 29 original studies. With the use of esmolol, significant attenuating effects were found on cardiovascular parameters in the first 5 min after stimulation; its shortening effects on seizure duration may be dose-related. With the use of labetalol, findings on cardiovascular effects were inconsistent during the first minutes after stimulation but were significant after 5 min and thereafter; seizure duration was scarcely studied. Landiolol attenuates heart rate but with inconsistent findings regarding arterial pressure (AP); seizure duration was mostly unaffected. Esmolol appears to be effective in reducing the cardiovascular response, although seizure duration may be affected with higher dosages. Landiolol can be considered a suitable alternative, but effects on AP need further investigation. Labetalol has been studied to a lesser extent and may have prolonged cardiovascular effects. The included studies varied in design, methodology, and the amount of exact data provided in the publications. Further study of beta-blocking agents in ECT is clearly necessary.

Abstract
PURPOSE This study was done to evaluate the effect of landiolol, an ultra-short-acting beta-blocker, on the hemodynamic response and the duration of seizure activity during electroconvulsive therapy (ECT). METHODS We designed a prospective, randomized, double-blinded, placebo-controlled, crossover study. Fourteen psychiatric patients participated. Landiolol (0.1 mg x kg(-1) or 0.2 mg x kg(-1)) or saline (placebo) was administered IV 1 min before the induction of anesthesia. Unconsciousness was induced with propofol 1.0 mg x kg(-1) IV, and muscle paralysis was produced with succinylcholine 0.6 mg x kg(-1) IV. Subsequently, electrical stimulus was administered to elicit a seizure, and the duration of the motor seizure activity was noted. RESULTS The heart rate (HR) and rate-pressure product (RPP) before ECT were significantly decreased in the 0.2 mg x kg(-1) landiolol group compared with these parameters in the placebo and 0.1 mg x kg(-1) landiolol groups. Both the 0.1 mg x kg(-1) and 0.2 mg x kg(-1) doses significantly attenuated the degree of tachycardia and RPP after ECT in comparison with the placebo group. Pretreatment with 0.2 mg x kg(-1) landiolol resulted in a significantly shorter duration of motor seizure than that in the placebo group (21 +/- 13 s vs 27 +/- 12 s). CONCLUSION As the landiolol dose of 0.2 mg x kg(-1) caused shorter seizure duration, and because the hemodynamic effects after ECT of the 0.1 mg x kg(-1) and 0.2 mg x kg(-1) doses were similar, it was concluded that a 0.1 mg x kg(-1) landiolol bolus was the appropriate dose pretreatment before ECT.

Abstract
We present the case of an 82-year-old man with 2 aortic aneurysms and multiple medical problems. The presentation describes the pre-electroconvulsive therapy (ECT) evaluations of the patient's problems and the measures used to control the possible dangerous fluctuations in blood pressure during the procedure. We hope that the successful outcome reported here will increase the likelihood that ECT will be considered for other patients with aortic aneurysms who have treatment-resistant depression.

Abstract
There are cases in the literature describing the use of electroconvulsive therapy (ECT) in patients with intracerebral aneurysms. We report the clinical course of a 60-year-old woman with a history of a recently ruptured intracerebral aneurysm and placement of a ventriculoperitoneal shunt that was successfully treated with ECT for major depressive disorder. Beta blockade with esmolol 20-50 mg was used to maintain her blood pressure, which ranged from 100/63 to 170/94 mm Hg. Propofol was used for anesthesia. There were no vascular complications secondary to the ECT procedure.

Abstract
There are no cases in the literature describing the use of electroconvulsive therapy (ECT) in a patient with an intraorbital vascular mass. We report the clinical course of a 69-year-old female with a cavernous hemangioma of the left orbit who was successfully treated with ECT for major depressive disorder. There were no apparent effects on the orbital hemangioma as a result of ECT-related blood pressure elevations measured up to 195/90 mm Hg despite pretreatment with intravenous esmolol. Modulation of ECT-related cardiovascular changes in the presence of intracranial or intraorbital vascular masses remains advisable to reduce the risk of an adverse vascular event during ECT. The use of propofol anesthesia appears to be preferable in such cases.

Abstract
The Ehlers-Danlos syndrome is an inheritable disorder caused by genetic defects of collagen. Hyperextensibility and fragility of the skin, joint hyperlaxity, and generalized fragility of the connective tissues, involving the hollow organs and arteries, are the cardinal features of this syndrome. Low bone density has also been reported. Theoretically, these patients can have an increased risk of rupture of blood vessels and of bone fractures. A patient with a schizo-affective disorder and Ehlers-Danlos Type I who received bifrontal ECT for a depressive episode is described. Even without specific measures to lower blood pressure, a course of ECT was finished without any complication.

Abstract
The 1990 American Psychiatric Association (APA) Task Force report on electroconvulsive therapy (ECT) suggests that there is an increased risk of complications in patients with intracranial vascular masses. There have been only a few published reports on the use of ECT in these patients. In this case report, an additional case is described that used ECT in the treatment of major depression in a 72-year-old patient with a venous angioma involving the left cerebellum. Brain imaging studies, neurosurgery, cardiology, and orthopedic consultations were obtained prior to ECT. Blood pressure was monitored closely throughout the course of ECT. Prior to each ECT, antihypertensive medication was given in addition to other pretreatment medications. Consistent with previously published reports, the patient did not experience any neurological deterioration or adverse effects. A brief review of the literature on the use of ECT in patients with venous angioma and other intracranial vascular masses is presented.

Abstract
ECT is often a necessary treatment for severe psychiatric disorders in patients with medical or neurologic comorbidity. Although the available data consist largely of cases and case series, ECT is effective in treating psychopathology despite the comorbidity. With appropriate precautions and monitoring during and after ECT, complications can be minimized.

Abstract
In 1990, the APA Task Force on ECT cited no "absolute" contraindications to ECT but "Substantial Risk" to be associated with ECT for patients with space occupying or other cerebral lesions with increased intracranial pressure and with bleeding or otherwise unstable vascular aneurysm or malformation. These findings indicate that patients with intracranial vascular masses are at increased risk for serious morbidity and mortality. Several authors have reported performing ECT in patients with intracranial vascular masses without adverse events by monitoring blood pressure both with and without pharmacologic intervention. Given the relatively recent change in practice of considering ECT for patients with intracranial vascular masses and the few number of cases thus far reported, we present a review of the existing literature and two additional cases of ECT performed with good result and no adverse events. With the cases we have presented, the literature now contains eight cases of ECT performed in patients with intracranial vascular masses, none of which had adverse outcomes. While such numbers do not establish unequivocal safety in this population, and the individual ECT practitioner must continue to make a risk/benefit analysis on a case-by-case basis, this report adds to the growing literature on the safety and efficacy of ECT for such patients.

Abstract
Electroconvulsive therapy (ECT) is a commonly used treatment modality for patients with major affective disorders that are unresponsive to pharmacological therapy. While ECT has been shown to be a very safe treatment, it is associated with transient hemodynamic alterations, including hypertension, which are associated with an increased risk of rupture of an intracranial aneurysm. We describe our use of the ultrashort acting beta-blocker, esmolol, for blood-pressure control in a woman with known cerebral aneurysmal disease who required ECT for treatment of recurrent major depression.

Abstract
OBJECTIVE An evaluation of the safety and efficacy of electroconvulsive therapy (ECT), for the treatment of patients with severe medical and neurological illness, was undertaken. METHOD The English-language literature reporting the use of ECT in patients with neurological and somatic disease was reviewed. This review included reports describing ECT used for the treatment of affective disturbances and catatonia in patients with concurrent neurological or somatic disease, as well as reports dealing with the efficacy of ECT for the treatment of certain neurological conditions for which it has been reported to have some benefit independent of its psychiatric effect. CONCLUSIONS ECT is safe and effective for the treatment of affective and catatonic disorders in patients with most neurological and medical diseases, including elderly and debilitated patients with multiple illnesses, if the specific medical risks are carefully evaluated in each case, and appropriate modifications of technique are used to reduce the risk of potential complications. Apart from its use in psychiatry, ECT has been reported to have therapeutic effects in Parkinson's disease, neuroleptic malignant syndrome, aggressive behavioral disorders following brain injury, certain forms of epilepsy, and some forms of delirium due to toxic or metabolic encephalopathies. The potential for ECT to play an active role in the clinical management of patients with these disorders, many of whom are presently refractory to maximal medical treatment, should be evaluated by systematic studies.

Abstract
Electroconvulsive therapy is usually accompanied by activation of the autonomic nervous system, which may be harmful in patients with cerebrovascular or ischaemic heart disease. We have compared this haemodynamic response in a series of 82 electroconvulsive treatments randomly assigned to receive either nitroglycerin 3 micrograms.kg-1, esmolol 2 mg.kg-1 or placebo. These drugs were given shortly after the suxamethonium and 2 min before the electroconvulsive therapy in all cases. Heart rate was significantly lower with esmolol 1 min after therapy as was blood pressure (systolic and diastolic). The pulse rate was higher following nitroglycerin than placebo, which in turn was higher than esmolol. The three groups did not differ with regard to seizure duration. The results demonstrate that esmolol is more effective than nitroglycerin in controlling the haemodynamic response to electroconvulsive therapy. With recent emphasis on stabilisation of heart rate in preference to blood pressure in at-risk cardiac patients, our study suggests that, in the doses selected, esmolol is preferred to nitroglycerin to control the heart rate response to electroconvulsive therapy.

Abstract
Twelve ASA physical status I-III patients were enrolled in a double-blind, prospective, randomized, three-way, within-patient crossover study designed to determine the effect of two standard esmolol bolus doses (100 and 200 mg) on the haemodynamic response and seizure duration during electro-convulsive therapy (ECT). Esmolol or placebo was administered one minute prior to induction of anaesthesia and exactly two minutes before ECT. Both the 100 and 200 mg bolus doses significantly blunted the maximum increase in heart rate (HR) and mean arterial pressure (MAP) following ECT in comparison with placebo. Compared with placebo, esmolol 100 mg decreased maximum HR by 23 +/- 3%, maximum MAP by 17 +/- 7% and maximum rate-pressure product (RPP) by 40 +/- 9%. Esmolol 200 mg decreased maximum HR by 25 +/- 3%, maximum MAP by 19 +/- 3% and maximum RPP by 42 +/- 5%. No significant difference was found between the two esmolol doses at corresponding measurement points before and after ECT. Treatment with esmolol 200 mg resulted in a significantly shorter mean seizure duration than with placebo. As the 200 mg dose caused a shorter seizure duration and the haemodynamic effects of 100 mg and 200 mg doses were similar, it was concluded that the 100 mg esmolol bolus dose was the better dose for ECT.

Abstract
To determine whether a standardized dose of esmolol can effectively attenuate the cardiovascular response to electroconvulsive therapy (ECT), 17 ASA physical status I-II patients were studied in a randomized within-patient, crossover design. Each patient received "no esmolol" during one ECT and three to five days later crossed over to the alternative treatment receiving an esmolol 80 mg bolus followed by 24 mg.min-1 infusion two minutes prior to induction of anaesthesia and continued for five minutes after induction. Esmolol blunted the maximum increases in heart rate (HR) by 26 per cent, mean arterial pressure (MAP) by 14 per cent, and rate pressure product by 37 per cent with significant differences (P less than 0.05) noted at one, two, three and four minutes after ECT (minutes five, six, seven, and eight of the esmolol infusion). There was no significant difference in seizure duration between the two groups and no adverse reactions occurred.

Abstract
Five patients known to be previously hypertensive but not currently receiving anti-hypertensive medications were studied for a total of twenty-six administrations of electroconvulsive therapy. Patients randomly received sublingual nifedipine 10 mg, 20 minutes prior to half of their treatments, and for the remaining treatments acted as their own controls. The use of nifedipine resulted in significant attenuation of the blood pressure response to therapy. Systolic pressure increase was 24 mmHg (SD 14) versus 62 mmHg (SD 24) (P less than 0.01). There was no difference in heart rate between the two groups. It is concluded that nifedipine reduces the pressor response to electroconvulsive therapy in individuals with a history of hypertension.
