A comparison of electrocardiographic changes observed during the “anoxemia test” on normal persons and on patients with coronary sclerosis

摘要: Abstract 1. In 157 cases of coronary sclerosis, the anoxemia test was electrocardiographically positive in 49 per cent, and furnished presumptive evidence insufficiency, by occurrence pain, another 20 cent. It thus helpful recognition a diminished reserve 69 2. The RS-T deviation each individual lead, as well total four leads which were employed, greater patients with sclerosis than 136 normal persons. 3. amount usually increased linear fashion relation to duration period anoxemia. Occasionally degree rose peak level then decreased, suggesting that compensatory mechanisms operated bring about favorable adjustment blood flow. 4. Comparison results on different showed no direct relationship between deviation; who breathed lowoxygen mixture for twenty minutes did not tend show those whose tests terminated earlier because pain. 5. incidence significant T-wave change deviation. 6. combination partial reversal 1 mm. or more Lead IVF, sole criterion test, observed less 2 cent found equal frequency Its use sign reaction has, therefore, been discontinued.
