Surgical treatment of tachyarrhythmias.

As a treatment for tachyarrhythmia, we have experienced 3 cases of Kent bundle division for WPW syndrome and 7 cases for implantation of atrial pacemaker. In two cases of Kent bundle division for A type and B type WPW syndrome, reappearance of premature supraventricular tachycardia was noticed but with less frequency and in number. A case of B type was cured surgically. Seven cases (including a case with elapse of 6 years) implanted with R-F atrial pacemaker termination of tachyarrhythmia resulted by rapid atrial pacing for 10 seconds.
