beat

 [bēt]
a throb or pulsation, as of the heart or of an artery.
apex beat the beat felt over the apex of the heart in the point of maximal impulse.
atrial beat an ectopic beat originating in an atrium.
capture beat
1. a heartbeat resulting from the production of a ventricular complex by a supraventricular source following a period of atrioventricular dissociation.
2. in cardiac pacing terminology, the successful pacing of the heart by a pulse generator.
dropped beat absence of one ventricular contraction.
echo beat reciprocal beat.
ectopic beat a heartbeat originating at some point other than the sinus node.
escape beat (escaped beat) heartbeats that follow an abnormally long pause.
forced beat an extrasystole produced by artificial stimulation of the heart.
fusion beat in electrocardiography, a P or QRS complex that results from the concurrent activation of the atria or the ventricles by two stimuli in the same chambers. An atrial fusion beat results when the sinus beat coincides with an atrial ectopic beat, when two atrial ectopic beats coincide, or when an atrial or sinus beat coincides with retrograde conduction from a junctional focus. A ventricular fusion beat results when a ventricular beat coincides with a sinus beat, a ventricular ectopic beat, or a junctional beat.
junctional beat an ectopic beat originating at the atrioventricular junction; see also junctional rhythm.
premature beat a cardiac event resulting from discharge by an atrial, junctional, or ventricular focus before the next expected sinus beat and at an interval from the last sinus beat that is shorter than its own intrinsic rhythm.
reciprocal beat a heartbeat resulting from an atrial or ventricular complex caused by a return of an impulse to its chamber of origin; called also echo beat.
sinus beat a heartbeat with sinus rhythm.
ventricular beat an ectopic beat originating in a ventricle.

ec·top·ic beat

a cardiac beat originating elsewhere than at the sinuatrial node.

ectopic beat

Spontaneous ectopic depolarization

ec·top·ic beat

(ek-top'ik bēt)
A cardiac beat originating elsewhere than at the sinuatrial node.

In order to filter the ectopic beats we used the method proposed in [17], using RR records.
Out of the 35(32.7%) patients with syncope, 13(37%) had positive Holter findings including monomorphic PVC's 6(17%), wandering pacemaker 4(11.4 %), atrial ectopic beats 1(2.8%), sustained run of SVT 1(2.8%) and ectopic SA node 1(2.8%).
As shown in table 3 and 4, we found a significant difference in terms of the mean numbers of total extra systoles and isolated ectopic beats between pure lidocaine with lidocaine + epinephrine and prilocaine with octapressin were significant in the second hour following the injection.
Multiple ectopic beats may lead to a rapid uncoordinated heartbeat (ventricular fibrillation) that can cause death.
Previous studies showed that ectopic beats originating from the PV propagated to the LA with characteristically long conduction time, often with conduction delay or block within the PV or at the PV-LA junction (3).
Ectopic beats are very common and don't damage your heart..
Pelationships between ventricular ectopic beats and ABP: Significant positive correlations were found between the number of ventricular ectopic beats and both 24-hour systolic BP variability (r = 0.54, p < 0.01) and 24-hour diastolic BP variability (r = 0.59, p < 0.01).
On admission, the patient showed a prolonged QT interval, ventricular ectopic beats, and runs of torsades de pointes tachycardia.
Recent clinical studies show that pulmonary veins (PVs) are an important source of ectopic beats, which could initiate paroxysmal tachyarrhythmias and AF, especially in the presence of certain cardioactive agents.
EXTRA heartbeats, known as ectopic beats, are quite common if you are tired or have drunk too much.
"People who live in soft-water areas, who use diuretics, or who are predisposed to magnesium loss or ectopic beats may require more dietary magnesium than would others."
