Abstract/OtherAbstract:
|
Twenty-four patients, mean age 42 years, with idiopathic dilated cardiomyopathy (DC) and no history of symptomatic ventricular arrhythmias underwent right ventricular programmed stimulation with up to 3 extrastimuli. Ventricular tachycardia (VT) was induced in 8 patients and ventricular fibrillation (VF) in 2. The VT was unimorphic in 2 and polymorphic in 6. No significant differences were noted between patients in whom arrhythmias were inducible and and those in whom they were not with regard to age, symptomatic class, arrhythmia severity or hemodynamic indexes. Over a mean follow-up of 12 months, 4 patients died, 3 suddenly and 1 with progressive heart failure. Only 1 of the 3 who died suddenly had inducible VT. One other patient with induced sustained unimorphic VT later presented with spontaneous sustained VT similar in rate and configuration to induced VT. In conclusion, VT or VF may be induced in approximately 40% of patients with DC and no history of symptomatic VT or VF. Inducibility of polymorphic VT or VF does not correlate with clinical or hemodynamic variables or with the risk of sudden death. However, induction of unimorphic VT may predict later occurrence of spontaneous unimorphic VT. |
