Study Notes
-
Continuous ECG monitoring is used in healthcare settings to identify myocardial ischemia or injury by monitoring ST segments.
-
Two types of ECG monitoring techniques are used: hardwire cardiac monitoring and telemetry.
-
Hardwire cardiac monitoring uses real-time ECG displays at the bedside and central monitoring station, with additional components for hemodynamic and respiratory parameters.
-
Telemetry is wireless and allows patients to ambulate while being monitored, using battery-operated transmitters with electrodes and a lead cable.
-
The number of electrodes and leads used depends on the lead system. Three-, four-, and five-lead systems are available, with five-lead providing the most options for monitoring different aspects of the heart.
-
Proper lead and electrode placement and customized alarm settings are important for accurate monitoring and reducing false alarms.
-
Ambulatory electrocardiography is used for longer-term monitoring at home, especially for intermittent arrhythmias, and data are transmitted to a central monitoring station via telephone or wireless technology.
-
Holter monitors are a type of ambulatory ECG monitor, worn for 24-48 hours with a digital memory device, requiring patient adherence and diary keeping for symptom correlation.
-
Continuous ECG monitoring can help detect arrhythmias, myocardial ischemia, and evaluate the effectiveness of treatment, among other uses.
