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 correct diagnosis is sinus rhythm, nonconducted premature atrial complexes (PACs), and junctional escape complex (Figure 2). The rhythm is irregular, but the long intervals are all the same (↔) ...

There is a regular rhythm with a rate of 36 beats/min. The fifth QRS complex (*) is early, has a different QRS morphology from the first four, and has a shorter RR interval. The initial four QRS ...

This is an accelerated junctional rhythm and P wave activity can be seen at the end of the QRS complexes in lead I and lead III. The QT is quite prolonged. This ECG was from a patient with genetic ...

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 ...

Sometimes, an abnormal EKG reading is a normal variation in a person’s heart rhythm. In other cases, it may be due to an underlying heart condition or a reaction to medication. An electrocardiogram ...

An EKG measures the heart’s electrical activity and can detect various issues, including heart attacks, rhythm abnormalities, and electrolyte imbalances. Seek immediate medical help if you experience ...
