Sc. Krishnan et al., REPRODUCIBLE INDUCTION OF ATYPICAL TORSADES-DE-POINTES BY PROGRAMMED ELECTRICAL-STIMULATION - A NOVEL FORM OF SOTALOL-INDUCED PROARRHYTHMIA, Journal of cardiovascular electrophysiology, 8(9), 1997, pp. 1055-1061
We present a patient with sotalol-induced polymorphic ventricular tach
ycardia that was seen only with programmed ventricular stimulation. El
ectrophysiologic studies performed prior to initiation of sotalol ther
apy revealed inducible monomorphic ventricular tachycardia. Possible u
nderlying electrophysiologic mechanisms are discussed.
