This ECG has ventricular pacing as seen by pacemaker spikes prior to each QRS complex, however has a more right bundle branch appearance.

Also note the pacing spikes on this ECG are quite large. Older devices that were unipolar appeared like this, however most current pacemakers have quite small pacemaker spikes on the ECG which can ...

Discussion The diagnosis is sinus tachycardia, right ventricular pacemaker, P-wave synchronous ventricular pacing (A-sensed V-paced), pseudo second-degree AV block due to failure of atrial sensing.

What is the mechanism for the progressive widening of QRS complexes and for the normal narrow QRS complexes observed in the ECG of a 52-yo male with recurrent syncope?

Researchers from the State University of New York at Binghamton investigated the use of a person's unique electrocardiograph (ECG) as a way to lock and unlock electronic health records.

An examination of the pacemaker confirmed that the lead impedance, pacing thresholds, and sensing values were again within normal ranges; however, a noticeable increase in RV lead impedance, with ...
