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 ...

The rhythm is regular at a rate of 120 beats/min. A pacemaker stimulus occurs before each QRS complex (→). This is ventricular pacing. Because the pacing rate is 120 beats/min, the mode of pacing must ...

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 ...

In the second season of the TV show "Homeland," terrorists assassinated the vice president of the United States (played by Jamey Sheridan) by hacking into his Wi-Fi-enabled pacemaker, and inducing a ...

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 ...

The nitric oxide-independent soluble guanylate cyclase activator ataciguat continued to show promise for slowing the progression of fibrocalcific aortic valve stenosis in phase I and II studies.

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 ...

If someone’s experiencing ongoing chest pain or other symptoms such as shortness of breath, an electrocardiogram will likely be a test your doctor orders. The electrocardiogram, also called an EKG or ...
