Implication

Supports continuous ECG for elusive events in select cases; hypothesis-generating and should not yet change practice.

Structured PICO

Does continuous cardiac telemetry improve the detection of angina pectoris or paroxysmal arrhythmias compared to conventional electrocardiography in ambulatory subjects?

P
Population
Ambulatory subjects (several cases)
I
Intervention
Continuous electrocardiograms over a ten-hour period using a dynamic electrocardiographic system
C
Comparator
Conventional electrocardiography
O
Outcome
Detection of angina pectoris or paroxysmal arrhythmiassurrogate

Continuous ambulatory ECG monitoring is effective for detecting transient arrhythmias and ischemic changes missed by standard resting ECG.
