The fusion band in V1: a simple ECG guide to optimal resynchronization?
In this heart failure patient with left bundle branch block, tailoring of the atrioventricular interval resynchronized myocardial contraction with left ventricular pacing alone, utilizing a sensed right atrial activity and the surface electrocardiographic pattern.
Our data suggest that, among patients with the clinical phenotype of cicatricial pemphigoid, AECP may be more frequent than previously assumed.
