S. Kinoshita et al., PAROXYSMAL SUPRAVENTRICULAR TACHYCARDIA INITIATED BY VENTRICULAR COUPLETS IN CONCEALED VENTRICULAR TRIGEMINY, Journal of electrocardiology, 28(1), 1995, pp. 69-72
A case report of a man with ventricular concealed trigeminy in whom ve
ntricular couplets initiating paroxysmal supraventricular tachycardia
were occasionally seen is reported. This is the first report on concea
led trigeminy with couplets. This strengthens the authors' previous su
ggestion that supernormal conduction may occur in the reentrant pathwa
y of extrasystoles, as a mechanism of ventricular couplets.
