The ecg in cardiac resynchronization therapy: influence of left and right ventricular preactivation and relation to acute response
Journal of Cardiovascular Electrophysiology, 07/10/2012
Bogaard MD et al. – ECG signs of biventricular electrical resynchronization are present over a wide range of LV preactivated VV delays but to a lesser extent during RV preactivation. The presence of complete left bundle branch block (LBBB) and longer Q–LVsense at baseline and signs of biventricular electrical resynchronization during CRT predict higher acute hemodynamic response.
