Cardiac rhythm management devices and electroconvulsive therapy: a critical review apropos of a depressed patient with a pacemaker

Electroconvulsive Therapy in Patients With Cardiac Implantable Electronic Devices: A Case Report and Systematic Review of Published Cases

OBJECTIVE

The aims of the study were to report the case of a 54-year-old man with recurrent depressive disorder with multiple medical comorbidities having a dual-chamber pacemaker, treated successfully with 11 sessions of electroconvulsive therapy, and to conduct a systematic review of published cases documenting the use of electroconvulsive therapy (ECT) in patients with cardiac implantable electronic devices (CIEDs) for treating major psychiatric disorders.

METHODS

We searched electronic databases (MEDLINE, PubMed, Google Scholar, Embase, Cochrane Library, PsycINFO, and Crossref) and included studies reporting on the use of electroconvulsive therapy in patients with CIEDs.

RESULTS

Thirty-five publications across 53 years (1967-2021) reported on 76 patients (including current report) who received a pooled total of 979 modified ECT sessions. The most common adverse events were premature ventricular contraction and hypertension. There have been no reports of serious adverse effects that necessitated the cessation of ECT.

CONCLUSIONS

Electroconvulsive therapy is a safe and efficacious treatment for major psychiatric disorders, and the presence of CIEDs should not delay or deter the use of ECT in these patients.

Electroconvulsive therapy for depression in a patient with an Inspire hypoglossal nerve stimulator device for obstructive sleep apnea: A case report

OUTCOME OBJECTIVES

METHODS: This is a case report of a patient who underwent placement and initiation of a hypoglossal nerve stimulator device in the context of receiving electroconvulsive therapy for bipolar depression between February and September 2016. To our knowledge, this has not yet been reported in the literature. Outcome measurements included successful device activation and successful device use throughout electroconvulsive therapy.

RESULTS

The patient underwent successful device implantation, activation, and use without disruption throughout electroconvulsive therapy sessions. No special device deactivation was required during electroconvulsive therapy sessions.

CONCLUSION

Obstructive sleep apnea is a common disorder that causes significant reduction in quality of life and is an independent risk factor for multiple comorbidities. Electroconvulsive therapy is an established treatment for medication-refractory depression with minimal risk in most patient populations. This is the first report in the literature of a patient undergoing ECT for bipolar depression with recent activation of Inspire hypoglossal nerve stimulator who had no disruption in the function of his implanted device.

Perioperative management of cardiac rhythm assist devices in ambulatory surgery and nonoperating room anesthesia

PURPOSE OF REVIEW

Patients with cardiac implantable electronic devices (CIEDs) frequently undergo various surgical procedures and in the past perioperative management involved only placing magnet over the device. New programming features, development of implantable cardiac defibrillator (ICD), cardiac resynchronization therapy, and increasing complexity of the operating room equipment have led to new sources of electromagnetic interference (EMI). A comprehensive understanding of the CIED is necessary to provide a timely and optimal care to the patients.

RECENT FINDINGS

Technological advancements and direct implantation of the transvenous implantable cardiac defibrillators into the heart have led to less clear lines between the pacemakers and the ICD. Subcutaneous ICD as well as the leadless transcatheter deployed intracardiac pacemaker development has complicated the issue further.

SUMMARY

Rapidly developing technologies and increasing number of patients with these devices coming for noncardiac surgeries necessitate continuous education of the anesthesia team regarding perioperative management of such devices.

Electroconvulsive therapy in 77-year-old patient with pacemaker: a case report

The treatment of a 77-year-old patient suffering from severe psychotic depression with a cardiac pacemaker is described. Because of treatment-resistant depression, electroconvulsive therapy (ECT) was introduced. In the course of ECT, there was a great improvement in his mental state without any cardiac complications. This case may be evidence for the safety and effectiveness of ECT in the elderly, even with cardiac comorbidities. Some recommendations for ECT in patients with pacemakers are discussed.

Effects of external electrical and magnetic fields on pacemakers and defibrillators: from engineering principles to clinical practice

The overall risk of clinically significant adverse events related to EMI in recipients of CIEDs is very low. Therefore, no special precautions are needed when household appliances are used. Environmental and industrial sources of EMI are relatively safe when the exposure time is limited and distance from the CIEDs is maximized. The risk of EMI-induced events is highest within the hospital environment. Physician awareness of the possible interactions and methods to minimize them is warranted.

Electromagnetic interference and implanted cardiac devices: the medical environment (part II)

Electromagnetic interference produced by medical equipment can interact with implanted cardiac devices such as pacemakers and implantable cardioverter-defibrillators. The most commonly observed interaction is in the operating room with electrosurgery. The risk of interactions can often be mitigated by close communication between the cardiac-device specialist and the anesthesiology/surgical team to develop a patient-specific strategy that accounts for factors such as type of device, type of surgery, and whether the patient is pacemaker dependent. Although magnetic resonance imaging should generally not be used in patients with implanted cardiac devices, several published guidelines provide strategies and recommendations for managing risks if magnetic resonance imaging is required with no suitable diagnostic alternatives. Other common sources of electromagnetic interference in the medical environment are ionizing radiation and left ventricular assist devices.
