A 70-year-old man with a personal history of hypertension, stroke, and single-vessel ischemic heart disease involving the right coronary artery treated with percutaneous placement of a drug-eluting stent, was admitted for syncope, hypotension, and severe bradycardia. A definitive DDD pacemaker was implanted with atrioventricular sensing set to 90ms and atrioventricular pacing set to 140ms.

An electrocardiogram was recorded during a follow-up visit (Figure), when the patient was asymptomatic.

(0.22MB).
