escape (redirected from autoregulatory escape)

escape /es·cape/ (es-kap´) the act of becoming free.

---

atrioventricular junctional escape , nodal escape one or more escape beats in which the atrioventricular node is the cardiac pacemaker.

vagal escape  the exhaustion of or adaptation to neural chemical mediators in the regulation of systemic arterial pressure.

ventricular escape  the occurrence of one or more ectopic beats in which a ventricular pacemaker becomes effective before the sinoatrial pacemaker; it usually occurs with slow sinus rates and often, but not necessarily, with increased vagal tone.

n.

1. A gradual effusion from an enclosure; a leakage.

2. A cardiological situation in which one pacemaker defaults or an atrioventricular conduction fails, and another pacemaker sets the heart's pace for one or more beats.

autoregulatory escape

after prolonged tissue hypoxia of shock, sympathetic-mediated vasoconstriction gives way to vasodilation in all organs.

vagal escape

the exhaustion of or adaptation to neural chemical mediators in the regulation of systemic arterial pressure.

ventricular escape

extrasystole in which a ventricular pacemaker becomes effective before the sinoatrial pacemaker; it usually occurs with slow sinus rates and often, but not necessarily, with increased vagal tone.
