[Conduction disorders during cardiac sarcoidosis (author's transl)].
The authors report 2 observations of auriculoventricular blockage developed during a mediastino-pulmonary sarcoidosis, requiring a heart pacer in the first case and corticosteroid treatment in the second. The frequency of the disorders of intracardiac conduction was evaluated by a retrospective study of 412 cases of mediastino-pulmonary sarcoidosis. Seventy two ECG were considered abnormal, a frequency of 17.2%. The disorders of auriculo-ventricular and intra-ventricular conduction represented a third of cases. What is known on the risk of lethal evolution of cardiac sarcoidosis in which those abnormalities are significant, justifies an electrophysiological investigation. The indications for a definitive cardiac stimulation and corticosteroid treatment are debated. On this final point, it seemed necessary to plan a prospective study to confirm the merits of the treatment and to define its modalities.
