We present the case of a 50-year-old man who had a dual-chamber pacemaker that was implanted because of symptomatic bradycardia. The pacemaker was programmed in a DDD mode, with a lower rate of 70 beats/min; upper rate, 120 beats/min; paced atrioventricular (AV) delay, 180 ms; sensed AV delay, 150 ms; and V-blanking period, 200 ms.
The Focus on ECGs section, published in the Texas Heart Institute Journal, presents a challenging ECG, a quiz, and a short comment on the interpretation of the ECG. This blog provides a collaborative opportunity to discuss each case in an effort to share the knowledge and the art of interpreting ECGs. Each discussion will close 2 weeks after publication.
