Don't forget the memory: Contribution of the T wave vector in localizing the site of origin of a monomorphic idiopathic ventricular tachycardia

Antonio Sorgente et al. J Cardiol Cases. .

Abstract

We report a case of cardiac memory following recurrent episodes of monomorphic idiopathic ventricular tachycardia and explain how it could be helpful in localizing the site of origin of the arrhythmia.

Keywords: Monomorphic ventricular tachycardia; T wave memory.

Figure 3
(A) Induction of ventricular tachycardia with atrial bursts from the high right atrium (HRA). From the top to the bottom electrocardiogram (ECG) leads I, II, III, aVR, V1, and V6 are displayed with electrograms from proximal and distal HRA (HRAd and HRAp) and proximal and distal right ventricular apex (RVAd and RVAp). (B) Site of successful ablation. From the top to the bottom ECG leads I, II, III, aVR, V1, and V6 are displayed with electrograms from HRAd and HRAp, proximal and distal ablation catheter (ABLp and ABLd) and RVAd and RVAp.
