[Hyperlipemia and functional state of the myocardius according to the analysis of the polycardiograph under conditions of submaximal physical exercise].
An analysis of polycardiographic parameters prior to and following treadmill exercises was conducted in 124 males, aged 39-59 years; in 57 of them the blood lipids level was normal, in 67--elevated (cholesterol level 260 mg% and higher in those aged 39--49 and 280 mg% and higher for those aged 50-59, or triglycerids--300 mg% and higher for both age-groups). In persons with elevated levels of lipids in blood during early restitution (after 2 min.) following submaximal physical exercises polycardiogrammes demonstrated a phase syndrome of hypodynamia irrespective of the fact whether an ischaemic depression of the ST segment appeared on the ECG tracings in response to the exercises or not. The functional deficiency of the myocardium in patients with hyperlipidemia is most probably explained by the hampered oxygen transport from the erythrocytes via the hyperlipidemic plasma to the heart muscle.
