A junctional rhythm occurs when the electrical activation of the heart originates near or within the atrioventricular node, rather than from the sinoatrial node. Because the normal ventricular ...

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 ...

There is a regular rhythm at a rate of 48 beats/min. The QRS complex duration is normal (0.08 sec), with a normal morphology and axis between 0° and 90° (positive QRS complex in leads I and aVF). The ...

In Atrial Arrhythmias the cause of the arrhythmia is in the upper chambers of the two atria. Supraventricular Tachycardia (SVT) is rapid heartbeats originating anywhere above the ventricles. It ...

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 ...

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 ...

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 ...
