[Effects of restored coronary circulation on nature and character of arrhythmia during attacks of angina pectoris in patients with ischemic heart disease].
The nature and frequency of cardiac arrhythmias were studied in 23 patients with coronary heart disease during anginal episodes accompanied by ECG ST-segment depression and elevation. All the ischemic episodes were divided into 2 periods: (1) that from the onset of ST-segment displacement to its maximum; (2) that from the first period to the return of ST segment to the baseline position. The predictive poor ventricular arrhythmias were more frequently recorded in the second period of ST-segment displacement. The occurrence of arrhythmias was demonstrated to be related to the degree of ST-segment elevation (depression) and the duration of the first period of ischemic episode in the second period of ST-segment displacement.
