INFLUENCE OF RESTORED CORONARY BLOOD-FLOW ON THE NATURE AND FREQUENCYOF CARDIAC-ARRHYTHMIAS IN PATIENTS WITH CORONARY HEART-DISEASE DURINGANGINAL EPISODES
Sv. Shalayev et al., INFLUENCE OF RESTORED CORONARY BLOOD-FLOW ON THE NATURE AND FREQUENCYOF CARDIAC-ARRHYTHMIAS IN PATIENTS WITH CORONARY HEART-DISEASE DURINGANGINAL EPISODES, Kardiologia, 32(4), 1992, pp. 10-12
The nature and frequency of cardiac arrhythmias were studied in 23 pat
ients 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 dis
placement to its maximum; (2) that from the first period to the return
of ST segment to the baseline position. The predictive poor ventricul
ar arrhythmias were more frequently recorded in the second period of S
T-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 per
iod of ST-segment displacement.
