[Survival after His bundle ablation for supraventricular arrhythmia. A 10-years experience in 317 consecutive patients].

Survival after His bundle ablation for supraventricular arrhythmias was analysed over 10 years (May 1982 to December 1992) in 312 consecutive patients (5 were lost to follow-up): 54 died (17.3%), 13 of sudden death (24%). The survival rates were 94.5% at 1 year (n = 256), 80.1% at 5 years (n = 88), 72.8% at 8 years (n = 20) and 51% at 10 years (n = 4); patients without apparent heart disease had a better prognosis. This series serves as a reference for other techniques of His bundle ablation.
