Why the study?
Does adjusting diagnostic criteria for FFT analysis of signal-averaged ECGs improve diagnostic accuracy in detecting patients with non-ischemic ventricular tachycardia?
Does adjusting diagnostic criteria for FFT analysis of signal-averaged ECGs improve diagnostic accuracy in detecting patients with non-ischemic ventricular tachycardia?
Adjusting diagnostic criteria values based on healthy cohorts can improve the diagnostic accuracy of FFT analysis of signal-averaged ECGs for detecting non-ischemic ventricular tachycardia.
May improve non-ischemic VT detection on signal-averaged ECG; leaves open prospective validation before clinical use.
