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 ...

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 ...

The compensatory pause after the PVC is slightly longer than the junctional escape interval and allows the junctional rhythm to escape for 5 beats. During this period, the P waves from the sinus ...

This ECG has a narrow QRS complex, a fast heart rate, regular rhythm and no identifiable P wave activity. It is likely that the P wave is buried in the QRS complex and the rhythm is junctional in ...

There is a regular rhythm, although the fourth and ninth QRS complexes (*) are slightly early — ie, a shorter RR interval. The QRS complexes are narrow and have a normal morphology and axis. The rate ...

Tachycardia is when your heart beats faster than normal, even when you’re not doing anything. Junctional tachycardia is a form of supraventricular tachycardia, a type of racing pulse caused by a ...

Background A routine sports evaluation identified constant alternation between a junctional and idioventricular rhythm in a 9-year-old child. During exercise testing, electrography demonstrated that ...

Perioperative arrhythmias may be induced by an imbalance between sympathetic and parasympathetic activities owing to excessive mental and physical stress. To date, no studies have been conducted on ...
