[Comparative evaluation of the structural characteristics of the circadian cardiovascular rhythms of healthy persons and in ischemic heart disease].
Certain indices of haemodynamics and ECG have been recorded in a biorhythmological study in 141 patients with ischaemic heart disease and in 26 practically healthy individuals. It was established that both the healthy individuals and the patients with ischaemic heart disease have diurnal rhythms of pulse rate, systolic and diastolic pressure, minute heart volume, R--R QRST, TQ intervals and R and T waves on ECG. The acrophases of diurnal rhythms of these indices in the healthy people are in mutual concordance with maximum figures during the daily and early evening hours. In the healthy the acrophase of T wave is seen during the day, in patient with ischaemic heart disease at night and early in the morning. This points to disorders of the bioelectric processes in the myocardium due to its nutritional changes over the 24 hours.
