Fused ventricular extrasystoles
WebApr 5, 2024 · Extrasystole is often a benign alteration of the heart rhythm. This is an early-onset pulsating contraction of the heart, which the affected individual can perceive to be an abnormal contraction, an extra or irregular heartbeat in comparison to the normal heartbeat, but which are detected and typified accurately only by instrumental examinations.

WebAn electrocardiogram taken from a 29-year-old man with old myocardial infarction is presented as an exemplary case of ventricular extrasystoles with fixed coupling. To explain the mechanism of ventricular extrasystoles with fixed coupling, a theoretical model is derived from the concept of longitudinal dissociation in the reentrant pathway. WebJan 1, 2004 · Right ventricular extrasystoles (RVES) with a left bundle branch block pattern and a vertical electrical axis are often seen in routine 12-lead ECGs. Patients with RVES are either asymptomatic or are referred for further evaluation to a specialized unit because of palpitations, vertigo, presyncope or syncope.

Premature ventricular contractions (PVCs) are extra heartbeats that begin in one of the heart's two lower pumping chambers (ventricles). These extra beats disrupt the regular heart rhythm, sometimes causing a sensation of a fluttering or a skipped beat in the chest.
