Alerts implanters to potential His injury during fixation; leaves open intra-Hisian block mechanisms.
Permanent His bundle pacing (HBP) is a physiological alternative to right ventricular pacing. Acute injury to the His bundle can occur during permanent HBP in the form of transient or permanent bundle branch blocks. Observations of mechanical injury to the His bundle during HBP lead fixation and electrophysiological response to HBP provides additional mechanistic insights into the pathology of bundle branch block and intra-Hisian atrioventricular block.
