Abstract :
This study presents evidence that bipolar electrograms acquired during ventricular tachycardia at sites affected by infarct had most of their power concentrated at frequencies below 30 Hz. By comparison, electrograms recorded from normal tissue had most of the power concentrated within 30-100 Hz. The results of this frequency domain analysis correlated well with results of common time domain techniques
