F. Vollmer et al., POLYMORPHOUS VENTRICULAR TACHYCARDIAS OCC URRING 3 MONTHS AFTER RADIOFREQUENCY HIS-BUNDLE RESECTION, Annales de cardiologie et d'angeiologie, 47(2), 1998, pp. 109-112
The authors report the case of a 73-year-old patient presenting with p
olymorphous ventricular tachycardias one to 3 months after radiofreque
ncy His bundle resection, as soon as the pacing frequency was reduced
to 70 bpm. The clinical history revealed the existence of a possible c
linical predisposition, as this patient had experienced an episode of
torsade de pointe induced by hydroquinidine, one year previously, This
case illustrates the importance of selecting a sufficiently high mini
mal stimulation frequency after His bundle resection.
