[Use of an additionally intensified ECG in diagnosing ischemic heart disease].
The article deals with the use of the additionally intensified ECG while conducting the bicycle ergometric test in 92 patients with coronary heart disease. It has been shown that when additionally intensified ECG is combined with bicycle ergometry the use of such parameters as the value of ST segment depression and the average rate of ST integral increases the resolving capacity of the technique. In patients with a positive result of the test according to the criterion of ST segment depression (0.1 mV or more), the ischemic changes on the additionally intensified ECG are determined one grade earlier than the threshold exercise and precede the anginal attack. In patients with an anginal attack without diagnostically significant changes on the ECG during 1 mV = 10 mm intensification, the employment of additionally intensified ECG makes it possible to identify the ischemic changes and confirm the pain attack by objective findings.
