[Possible role of a cardiac factor in limiting the walking perimeter in the treadmill test in the arteritis patient].

Electrocardiographic modifications appearing during a treadmill test undergone by 145 patients with arterio-sclerosis obliterans at stage II without coronary antecedents and with normal resting electrocardiograms were studied. Twenty per cent of the patients had to discontinue the test (slope 12%, 3,8 km/h). A repolarization anomaly of ischemia type appeared in 13% of the cases (19 patients) and a rhythm disorder in 1%. Hence systematic monitoring of the electrocardiogram during walking test can enable subjects with high coronary risk to be singled out.
