Overview

Pathologic bradycardias are caused by disorders of impulse generation (impaired automaticity at SA node), impulse conduction (heart block) or escape pacemakers and rhythms. Bradycardia can be underlain by several causes, which are best divided into cardiac and non-cardiac causes or based on the location of the abnormality.

Causes

  • Drugs:

Life Threatening Causes

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


Common Causes

Causes Based on Pathophysiologic Origin of Impulse

From the Atria

Respiratory Sinus Arrhythmia

Sinus bradycardia

Sinoatrial block

Sinus arrest

Sick sinus syndrome


First degree AV block

Second degree AV block

Complete or third-degree AV block

Short PR interval

From the AV junction

Junctional bradycardia

From the Ventricles

Isorhythmic A-V dissociation

Idioventricular rhythm

Ventricular escape beat

Combined List of Causes in Alphabetical Order
