Having an accelerated junctional rhythm occurs when the atrioventricular node in your heart beats too quickly. It happens as a result of damage to your heart’s primary natural pacemaker. There’s no ...

Junctional rhythm is an irregular heart rhythm that stems from a natural pacemaker in the heart known as the atrioventricular junction. The heart has several built-in pacemakers that help control its ...

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 ...

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 ...

The heart may be small, but its rhythm powers life. When something throws that rhythm off—especially after surgery—it can become a race against time to restore balance. For decades, doctors have ...

A junctional escape rhythm is when the heartbeat starts in a different part of the heart than it should. This type of arrhythmia may not need treatment, but a doctor does need to investigate the ...
