[Which sports after 50 years of age?].

Between the ages of 30 and 80, the physiological abilities decrease: muscular, cardiovascular, respiratory, neurological, etc. The consequences on sports activities are obvious: limitation of the performance per se, quantitatively as well as qualitatively as well as the ability to recover. This is combined with a danger: coronary atherosclerosis responsible for 90 p.

[Is computed interpretation of electrocardiograms suitable for a general medicine department?].

Computed interpretation of electrocardiograms may be needed as French hospitals are divided into units in which physicians belonging to other specialities than cardiology may be in charge of internal medicine patients. We experimented two rival systems: SADE and CARDIONICS. Recordings were taken in the wards, on paper and magnetic tape.

[Severe hyperkalemia in cardiac patients].

Hyperkalaemia with severe myocardial consequence may complicate the treatment of heart failure. In five patients who developed kalaemia ranging from 6.5.

[Epicardial cartography and surgical treatment by simple ventriculotomy of certain resistant re-entry ventricular tachycardias].

Intraventricular reentry has been prooved by pre-operative electrophysiological studies in two patients without coronary artery disease and resistant ventricular tachycardia. A simple ventriculotomy oriented by epicardial mapping during tachycardia was successfull with a background of 9 and 14 months respectively. In addition, delayed epicardial potentials put into evidence an intraventricular reentry in human myocardium.
