[The end portion of the ECG ventricular complex and intracardiac hemodynamics during exercise in patients with ischemic heart disease and hypertension].
Comparison of exercise-induced variations in the end portion of electrocardiographic ventricular complex and the echocardiographic pattern showed that amplitude changes and T-wave inversion in response to exercise developed where hemodynamic support was less economical in patients with stage-IIA essential hypertension. In essential hypertension, the spread of myocardial ischemic area, as determined by the number of ECG leads showing post-exercise ST displacement, was related to the type of hemodynamic response. The number of ECG leads with displaced ST is a factor to be considered in the assessment of exercise test results.
