What are the types of bradyarrhythmias?

A bradyarrhythmia is a slow heart rhythm that is usually caused by disease in the heart’s conduction system. Types of bradyarrhythmias include:

• Sinus node dysfunction: Slow heart rhythms due to an abnormal SA node.
• Heart block: A delay or complete block of the electrical impulse as it travels from the sinus node to the ventricles. The level of the block or delay may occur in the AV node or HIS-Purkinje system. The heartbeat may be irregular and slow.
