Use of Correlation Waveform Analysis in Discrimination Between Anterograde and Retrograde Atrial Electrograms During Ventricular Tachycardia

Correlation Waveform Analysis. Introduction: Discriminating between ventricular tachycardia (VT) with 1:1 ventriculoatrial association and sinus tachycardia can be difficult, even when assisted by intracardiac tracings. In this study, we used a new computer algorithm to perform correlation waveform analyses on intracardiac atrial electrograms to help distinguish between VT and sinus tachycardia.
