Diagnostic Monitoring
Typical Use
Continuous ambulatory ECG recording for 2472 hours.
Description
A portable, battery powered electrocardiographic recorder worn by patients to capture continuous cardiac rhythm data over extended periods, typically 24 to 72 hours, to detect intermittent arrhythmias, correlate symptoms with rhythm disturbances, and evaluate rate variability. The device records multiple leads or a single lead tracing and stores data for later download and analysis by clinicians or automated software; patient symptom diaries and activity logs improve correlation between events and tracings. Holter monitoring is noninvasive and widely used for syncope, palpitations, and post?procedural surveillance, and interpretation requires artifact recognition, correlation with clinical context, and sometimes extended monitoring or event recorders when arrhythmias are infrequent.
