S. Kinoshita et al., MECHANISM OF BRADYCARDIA-DEPENDENT APPEARANCE OF MANIFEST EXTRASYSTOLES IN CONCEALED VENTRICULAR TRIGEMINY, Chest, 106(1), 1994, pp. 289-291
A man with ventricular extrasystoles is described. To our knowledge, t
his is the first report of bradycardia dependent appearance of manifes
t extrasystoles in concealed trigeminy. The mechanism was satisfactori
ly explained, using the concepts of longitudinal dissociation and conc
ealed 3:2 Wenckebach periodicity in the reentrant pathway of extrasyst
oles.
