[Fulguration of the bundle of His. An explanation based on 128 consecutive personal cases].

Fulguration of the bundle of His consists is interrupting or markedly slow-down the atrio-ventricular conduction, in order to suppress or markedly decrease the symptoms related to refractory atrial arrhythmias. With a consecutive series of 128 cases, it is possible to specify the main indications and present a simplified technique, using Josephson's catheter. At 3 months, the results are as follows: 3rd degree atrio-ventricular block in 80 p. cent of the cases, 1st degree atrio-ventricular block in 10 p. cent, with failure in 10 p. cent of the cases. The immediate complications are rare and benign. Late complications are essentially related to the type of cardiac stimulation offered to the patient. The ventricular stimulation with dependent frequency (particularly on ventilation), enables most patients to return to a normal activity.
