What does atrial escape rhythm mean?

Atrial escape rhythm refers to an ectopic beat caused by passive impulse from other potential pacemaker points in the atrium when the sinus node or atrium is excited delayed or there is outflow block. Three or more such activities occur continuously, forming an atrial escape rhythm. Escape and escape rhythm are physiological protective mechanisms. The most common is atrioventricular junction escape, followed by ventricular escape, and atrial escape is relatively rare. Escape beats are mostly temporary, mainly secondary to sinoatrial block, sinus arrest, significant and slow sinus bradycardia and atrioventricular block, which are their own protective mechanisms.
