Key result
Ambulatory ECG improves arrhythmia detection over resting ECG by capturing over 100,000 daily cardiac cycles.
Why the study?
The standard 12-lead resting ECG's brief duration limits detection of life-threatening arrhythmias and assessment of antiarrhythmic therapy effectiveness.
Comparison

Supports ambulatory ECG for intermittent arrhythmia detection; leaves open optimal protocols pending prospective validation.
Ambulatory ECG monitoring offers significant advantages over standard resting ECG for detecting intermittent arrhythmias and evaluating antiarrhythmic therapy.
J. S. Schroeder (1976) conducted a review in Cardiac arrhythmias. Ambulatory electrocardiographic monitoring vs. Standard 12-lead resting electrocardiogram was evaluated. Ambulatory electrocardiographic monitoring records over 100,000 cardiac cycles in a 24-hour day, providing a better estimate of arrhythmias than the 50 to 100 cycles of a standard resting ECG.
