Overview

Junctional tachycardia may oocur either as a result of enhanced automaticity of the AV node when the SA node is bradycardic or discharges at a slower rate than the AV node (e.g. myocardial infarction, digitalis toxicity) or when an ectopic focus with an abnormal automaticity develops within or adjacent to the AV junction. Other causes include: hypoxia, electrolyte imbalance, and infections such as rheumatic fever, Lyme disease.

Causes

Life Threatening Causes

Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.
