This ECG shows ventricular pacing. Note the pacer spike prior to each QRS complex, most apparent in leads V5 and V6. The P waves appear sinus in origin and have no association with the QRS complexes ...

A 76-year-old woman with known ischemic cardiomyopathy, a left ventricular ejection fraction of 25%, and a previously inserted pacemaker presents to her cardiologist concerned that there is a problem ...

The rhythm is regular at a rate of 78 beats/min. Before each QRS complex, there are two pacing stimuli (+,v) with a very short interval (0.06 sec) between them. They are both ventricular pacing ...

If the ventricular pacing is originating in the right ventricle like a normal pacemaker, a left bundle branch morphology will be present. This occurs since the right ventricle is activated first and ...

The cardiac pacemaker harmlessly dissolves over the course of 35 days. (Courtesy: Northwestern University) Temporary cardiac pacemakers provide essential pacing for patients with short-term heart ...

HEART RHYTHM CASE REPORTS PUBLISHES NOTABLE CASE DETAILING FIRST USE OF AI-GUIDED ECG MAPPING FOR LEFT BUNDLE BRANCH AREA PACING Case Report Demonstrates How vMap ...

Outcomes against which the relative effectiveness of dual‑chamber and single‑chamber pacing were assessed included the incidence of pacemaker syndrome, exercise capacity, functional status, quality of ...
