Question

Quizplus · Accepted Answer

A junctional escape rhythm occurs when the SA node fails to initiate the electrical activity and one of the backup pacemaker sites, typically the AV node, takes over to maintain a regular heartbeat. Heart block rhythm refers to disturbances in the electrical conduction system of the heart, which can result in a range of abnormalities in heart rhythm. Asystole refers to a complete absence of electrical activity and cardiac output, and is considered a medical emergency. Normal sinus rhythm refers to a regular heartbeat initiated by the SA node.
