Examples

1. Two escape beats are shown between 5-8 seconds.
2. He distributed hand-held " beats were designated " fire escape beats ".

5. The pause ends with a P wave, instead of a junctional escape beat the way a sinus arrest would.
6. Ventricular escape beats differ from ventricular extrasystoles ( or premature ventricular contractions ), which are spontaneous electrical discharges of the ventricles.
7. If the rate from both the SA and AV node fall below the discharge rate of ventricular pacemaker cells, a ventricular escape beat ensues.
8. This is followed by a period of delayed sinus activity which initiates a takeover response by the ventricular pacemaker cells resulting in a ventricular escape beat.
9. When the sinus rate falls below the discharge rate of the AV node, this becomes the dominant pacemaker, and the result is called a junctional escape beat.
10. It indicates a failure of the electrical conduction system of the heart to stimulate the ventricles ( which would lead to the absence of heartbeats, unless ventricular escape beats occur ).
