Time‐ Versus Frequency‐Domain Analysis in Predicting Cycle Length of Inducible Ventricular Tachycardia After Myocardial Infarction
Why the study?
Do time- and frequency-domain analyses of signal-averaged ECGs differ in their ability to predict the cycle length of inducible ventricular tachycardia after myocardial infarction?
Population
60 consecutive patients with myocardial infarction and 30 healthy control subjects
Design

Implication
Supports time-domain SAECG for post-MI VT insights; leaves open prospective validation before clinical adoption.
Structured PICO
Do time- and frequency-domain analyses of signal-averaged ECGs differ in their ability to predict the cycle length of inducible ventricular tachycardia after myocardial infarction?
P
Population
60 consecutive patients with myocardial infarction and 30 healthy control subjects
I
Intervention
Time-domain and frequency-domain analysis of signal-averaged ECG recordings
O
Outcome
Cycle length of inducible sustained ventricular tachycardia (VT) during programmed ventricular stimulationsurrogate
Time-domain analysis of signal-averaged ECGs, but not frequency-domain analysis, correlates with the cycle length of inducible sustained ventricular tachycardia in patients with prior myocardial infarction.
