[Study of systolic times by external phonomechanocardiography in myocardial infarction. 2. Results of sensitizing tests: methoxamine, venous tourniquets, isomeric contration].
In an attempt to improve the quality of information provided by measuring the systolic times, the effect of three thpes of sensitising test was studied: the test with venous tourniquets on the lower limbs, the test with methoxamine, and the test under isometric exercise. In none of these tests was there found to be a statistically significant difference between the controls and the patients with myocardial infarction, with or without left ventricular failure. Taken as a whole, however, the sensitising tests studied tended to accentuate the abnormalities in the systolic times established under basal conditions in patients with myocardial infarction more grossly than in controls.
