[Epicardial mapping in the syndrome of premature ventricular excitation. 2].

Epicardial mapping was carried out in 20 patients suffering from Wolff-Parkinson-White's syndrome with supraventricular tachycardias resistant to drug therapy. The automated mapping system elaborated at the A.N.

[Epicardiac mapping in premature ventricular excitation syndrome. I. Method and technic of epicardiac mapping].

Using specially designed electrodes, an automated system for arrhythmia diagnosis and an all-purpose programmed electrocardiostimulator, the authors succeeded in obtaining a precise real-time chart of the electrical excitation distribution on the heart surface. The system was tested during open heart surgery in patients with congenital heart disease.
