The pathophysiology of Premature ventricular contraction (PVC) induced cardiomyopathy (PVC-CM) remains unclear. AV dissociation (AVD) during PVCs is known as atrial at the time PVC. AVD has been implicated a potential trigger and predictor PVC-CM, especially early since it results in an increase LA pressure due to mitral valve closure. goal this study was assess short- long-coupled PVCs, its co...

A comprehensive study on open chest anesthetized dogs was done to investigate the influence of intraventricular activation order on cardiac performance and to evaluate the degree to which entry into the conduction system might contribute to the synchrony of contraction in the ventricle opposite the stimulus site. Intraventricular pressures were measured during premature beats from several ventr...
