Mechanism of bradycardia-dependent appearance of manifest extrasystoles in concealed ventricular trigeminy.
A man with ventricular extrasystoles is described. To our knowledge, this is the first report of bradycardia dependent appearance of manifest extrasystoles in concealed trigeminy. The mechanism was satisfactorily explained, using the concepts of longitudinal dissociation and concealed 3:2 Wenckebach periodicity in the reentrant pathway of extrasystoles.
