heartbeat,beat,pulse,pulsation- the rhythmic contraction and expansion of the arteries with each beat of the heart; "he could feel the beat of her heart" extrasystole- a premature systole resulting in a momentary cardiac arrhythmia Based on WordNet 3.0, Farlex clipart collection. © 2003-201...
As the name implies, an extrasystole occurs outside the regular sequence of heartbeats and is therefore an arrhythmia. PVC is a synonymous term. An extrasystole can arise supraventricularly and propagate through the heart's specialized conduction system, activating the ventricles in the normal ...
arrhythmia; a ventricular rate of 160–250 beats/min; irregularRR intervals; and a cycling of the QRS axis through 180 degrees every 5–20 beats. TdP is typically short-lived and terminates spontaneously. However, most patients experience multiple episodes of the arrhythmia, and episodes...

and frequent atrial ectopic beats (more than 1000 beats per day) on any available ECG and ambulatory Holter monitors. We planned Holter monitoring whenever any supraventricular arrhythmia was detected or suspected with multiple rest and exercise ECGs as well as patient's complaints. In this study,...
It was encountered more frequently in younger subjects; the only patient over 45 developed the arrhythmia as a complication of therapy. This incessant mechanism may explain some cases in which antiarrhythmic treatment does not control reciprocating tachycardia in the WPW syndrome, but such a mechanism...
An extra beat arising in the lower chambers of the heart is commonly referred to as a ventricular premature complex (VPC). It is a common arrhythmia and is often benign. However, it can cause unnerving symptoms such as palpitations, chest-thumping, strong or hard beats, and skipped beats. ...
