Development of “false” atrioventricular block in a patient after heart transplantation: case report
https://doi.org/10.35336/VA-2023-1-10
Abstract
A clinical case of the development of bradycardia after heart transplantation is described. Electrocardiography data corresponded to atrioventricular (AV) block against the background of sinus bradycardia, which was the reason for the implantation of a pacemaker. Using intraprocedural electrophysiological study, the absence of data for AV dysfunction was revealed. The concept of AV block arose since the contracting part of the recipient’s atria was electrically isolated from the donor’s atria, there was no atrial activity in the donor heart, and the ventricles contracted due to AV node rhythm, which created the possibility for the presence of two dissociated rhythms.
