Continuous ST-Segment Monitoring

Proper skin preparation and electrode placement decreases alarms on a telemetry unit

BACKGROUND

An estimated 85% to 99% of electrocardiographic (ECG) alarms are false, leading to alarm fatigue, which is associated with increased risk of death among hospitalized patients.

OBJECTIVE

The aim of this study was to examine the effect of proper skin preparation and electrode placement on frequency of ECG alarms on a telemetry unit.

METHOD

A prospective descriptive design was used to test the effect of proper skin preparation and ECG electrode placement. Purposive sampling of patients (n = 15) admitted to a telemetry hospital in a suburban Veterans Affairs Medical Center was used. Alarms were counted for 24 hours after admission, electrodes were replaced using proper technique, and alarms were counted for 24 hours after electrode change. Bootstrapping was used to double the sample size for analysis.

RESULTS

Electrocardiographic alarms decreased significantly (P < .05) after proper skin preparation and electrode placement (95% confidence interval, 1.273-82.327).

DISCUSSION

Proper skin preparation and ECG electrode placement reduced alarms. Reducing alarm frequency is vital to decreasing alarm fatigue and increasing patient safety.

Applying evidence at the bedside: a journey to excellence in bedside cardiac monitoring

Bedside cardiac monitoring is a nursing domain, and lead selection is determined by the monitoring needs of the patient. Understanding the rationale behind the evidence empowers the bedside critical-care nurse to make monitoring decisions that best meet the monitoring needs of the patient. This article discusses a journey to move beyond the sacred cows of monitoring and utilize the available literature to make monitoring choices that best meet the needs of each individual patient.

Continuous ST-segment monitoring: raising the bar

ST-segment monitoring is recommended by clinical experts to assist in the early detection of transient myocardial ischemia; however, a gap exists between the recommendations and clinical practice. This article provides a review of research to support the use of ST-segment monitoring in a variety of clinical situations. Patient selection for monitoring, techniques, and strategies to facilitate successful implementation of ST monitoring are included. Nurses are encouraged to advocate for patients by raising the bar of electrocardiogram monitoring practice to aid in optimizing patient outcomes.

Recommendations for the structure, organization, and operation of intensive cardiac care units

Two major changes in patient characteristics and management occurred recently that demand distinctive alterations in the function of the intensive cardiac care unit (ICCU). These changes include the introduction of an early invasive strategy for the treatment of acute coronary syndromes, enabling early recuperation and shorter need for intensive care on the one hand, while the number of older and sicker patients requiring prolonged and more complex intensive care is steadily increasing. A task force of the European Society of Cardiology Working Group on Acute Cardiac Care was set to give a modern updated comprehensive recommendations concerning the structure, organization, and function of the modern ICCUs and intermediate cardiac units. These include the statement that specially trained cardiologists and cardiac nurses who can manage patients with acute cardiac conditions should staff the ICCUs. The optimum number of physicians, nurses, and other personal working in the unit is included. The document indicates the desired architecture and structure of the units and the intermediate cardiac unit and their relations to the other facilities in the hospital. Specific recommendations are also included for the minimal number of beds, monitoring system, respirators, pacemaker/defibrillators, and necessary additional equipment. The desired function is discussed, namely, the patients to be admitted, the length of stay, and the relocation policy. A uniformed electronic chart for ICCUs is advised, anticipating a common European database.

Classification of acute coronary syndromes using the 12-lead electrocardiogram as a guide

The management of patients with acute coronary syndromes (ACS) is becoming more complicated. With the advent of new therapies and surgical techniques, the likelihood that patients will make a full recovery improves. Cardiovascular disease remains the leading cause of death for adults in the United States, and with continually increasing trends such as obesity and diabetes, will likely remain so in the future. With the introduction of improved therapies, the numbers of patients dying after their first myocardial infarction continues to decline. Electrocardiogram (ECG) technology has improved, and further research has improved its sensitivity and specificity allowing for earlier, more consistent diagnosis of ACS. As a result, guidelines have been developed to assist nurses and clinicians in the management of patients with ACS. Nurses are in a unique position to provide primary triage, recognize ACS based on the patient's presentation and initial 12-lead ECG, and initiate an appropriate response. Key elements of 12-lead ECG interpretation and their application to established guidelines are essential skills for nurses working in clinical arenas frequented by patients with ACS.
