AF, atrial fibrillation; BiV = biventricular; BIVAT-90 = time for 90% biventricular activation; BiVDI = biventricular dyssynchrony index; CHB, complete heart block; LBBB, left bundle branch block; LVAT95 = time for 95% left ventricular activation; LVDI = left ventricular dyssynchrony index; RVAT90 = time for 90% right ventricular activation; SR, sinus rhythm.
