[Change in the circadian rhythms of the ECG T-wave value in ischemic heart disease].
Rhythmological study of the T wave on the ECG was conducted for 24 hours in 25 healthy individuals and 141 patients with ischemic heart disease. A daily rhythm of changes in the blood supply to the myocardium was revealed. Its maximum values were recorded during the day in healthy individuals and during the night and in the morning in sick individuals, i.e. the rhythm in patients was distorted and desynchronized. Consequently, atherosclerosis of the coronary arteries as an organic disease has an effect on the natural daily rhythm of the blood supply to the myocardium.
