Study Notes
- Continuous ECG monitoring is used to identify myocardial ischemia or injury by observing ST segments in health care settings.
- Two types of ECG monitoring techniques are used: hardwire cardiac monitoring and telemetry.
- Hardwire cardiac monitoring is used in critical care units and EDs, provides real-time ECG display, and can monitor hemodynamic and respiratory parameters.
- Telemetry is wireless and allows patients to ambulate while monitoring ECG, with batteries changed every 24 to 48 hours.
- ECG lead systems determine the number of leads and the type of monitoring. Five-lead systems provide the most options and monitor the anterior wall of the left ventricle.
- Proper lead and electrode placement and alarm customization are essential to reduce false alarms and alarm fatigue.
- Ambulatory electrocardiography is used for longer-term monitoring of intermittent arrhythmias, chest pain, myocardial ischemia, and treatment effectiveness.
- Holter monitors are small, portable devices that record ECG activity for 24 to 48 hours and require patient adherence for accurate results.
- Ambulatory electrocardiography can help diagnose arrhythmias, evaluate the functioning of ICDs and pacemakers, and detect myocardial ischemia.
- Different devices and methods for ambulatory electrocardiography include event monitors, mobile cardiac telemetry, and implantable loop recorders.
- Continuous monitors provide long-term ECG data but do not offer real-time analysis or immediate results for the patient or healthcare provider.
Learn about the basics of electrocardiography and how the electrical impulse that travels through the heart can be visualized using an electrocardiogram (ECG). Explore the specific waveforms that reflect each phase of the cardiac cycle and understand the graphic representation of the electrical current.
