The informative value of changes of electrocardiographic elements in dosed physical load in the diagnosis of ischemic heart disease


, : The informative value of changes of electrocardiographic elements in dosed physical load in the diagnosis of ischemic heart disease. Terapevticheskii Arkhiv 57(9): 25-29

The authors provide the data obtained on retrospective analysis of 30 ECG recorded in 30 men with coronary heart disease (CHD), confirmed by the clinical and coronarography data, during bicycle ergometry. The amplitude of the R wave in the V5 lead and the total amplitude of the R wave in the V3-V6 leads were analyzed. The area of the QRS complex was calculated as a sum of three triangles. While drawing up a triangle according to the S wave one of the sides went over from the S wave top across the J point till crossing the isoline. The amplitude and duration of the T wave were also take into consideration. It was established that evaluation of the area of the QRS complex, whose magnitude is an integrated index of changes in all the elements of the ventricular complex, is of the greatest value in the diagnosis of CHD during bicycle ergometry.
