This case report highlights an unusual electrocardiogram finding following dual-chamber pacemaker implantation in an elderly patient with infrahisian atrioventricular block.
A hypertensive old man in his 80s with no other known comorbidities presented with exertional fatigue for 3 months and an episode of presyncope 2 days prior to presentation. Bradycardia (heart rate of 45/min) was detected during blood pressure measurement, and a 12-lead ECG revealed 2:1 atrioventricular block with complete right bundle branch block (RBBB) and normal PR interval on conducted beats (figure 1A). Echocardiography demonstrated a structurally normal heart. In view of probable infrahisian atrioventricular block and symptomatic status, he underwent dual-chamber permanent pacemaker implantation. Postpacemaker implantation ECG is shown in figure 1B. …

Naik et al. (2021) conducted a case report in 2:1 atrioventricular block with complete right bundle branch block (n=1). Dual-chamber permanent pacemaker implantation was evaluated on Postpacemaker implantation ECG findings. A hypertensive man in his 80s with 2:1 atrioventricular block and complete right bundle branch block underwent dual-chamber permanent pacemaker implantation, followed by an unusual electrocardiogram.
