Normal sinus rhythm left bundle branch block

WebVentricular activation times and their standard deviation (two parameters of electrical dyssynchrony) were computed for sinus rhythm (the gold-standard for optimal synchronization), right ventricular electrical pacing (simulating left-bundle branch-block and dyssynchrony) and multi-site optogenetics pacing (Fig. 38.7 J and K). WebLeft bundle branch block is a problem with the heart’s electrical wiring (conduction) system. Your heart has 4 chambers. The 2 upper chambers are called atria, and the 2 lower chambers are called ventricles. In a healthy heart, the signal to start your heartbeat begins in the upper right chamber of the heart (right atrium).
