LBBAP: Left bundle branch area pacing, LBBP: Left bundle branch pacing,
LV: left ventricular, RV: right ventricular, IVS: interventricular
septum, LBB: Left bundle branch, RBB: Right bundle branch, MI:
myocardial infarction
Example 1: Twelve-lead electrocardiogram (ECG) at baseline and
following BVP, HBP and apical RV pacing. The baseline ECG demonstrates a
QRS duration of 86 ms. During BVP and HBP the QRS duration remains
narrow, 100ms and 92ms, respectively, in contrast to its significant
widening during apical RV pacing, where it reaches 196ms. BVP;
