Atrial Escape Beat
Figure 1: ECG Strip
An atrial escape beat occurs after a long sinus pause resulting from sinus node exit block or sinus node arrest. Atrial escape beats can become a sustained atrial rhythm when three or more escape beats occur in a row at a rate above 60 bpm.
- Escape beats/rhythms provide protection against total cardiac standstill in the event of sinus node failure or complete heart block.
