Comparative Effectiveness of Exercise Testing and Continuous Monitoring for Detecting Arrhythmias in Patients with Previous Myocardial Infarction
Why the study?
Does continuous ECG monitoring improve the detection of significant arrhythmias compared to submaximal treadmill exercise testing in patients with previous myocardial infarction?
Population
60 patients with previous myocardial infarction
Comparison
10 hours of continuous ECG monitoring during… vs Submaximal treadmill exercise testing

Implication
May detect more serious arrhythmias than treadmill testing post-MI; hypothesis-generating and should not yet change practice.
Structured PICO
Does continuous ECG monitoring improve the detection of significant arrhythmias compared to submaximal treadmill exercise testing in patients with previous myocardial infarction?
P
Population
60 patients with previous myocardial infarction
I
Intervention
10 hours of continuous ECG monitoring (Holter technique) during normal activity
C
Comparator
Submaximal treadmill exercise testing
O
Outcome
Detection of significant arrhythmiassurrogate
Continuous ECG monitoring is more effective than submaximal treadmill exercise testing for detecting serious arrhythmias in patients with previous myocardial infarction.
