EXERCISE-INDUCED QRS DURATION CHANGES IN PATIENTS WITH CORONARY-ARTERY
DISEASE-APPEARING WALKTHROUGH ANGINA

Περίληψη:
Two patients with coronary artery disease appearing as ‘’walkthrough”
angina underwent a treadmill exercise test. During the exercise, the
patients appeared to have anginal pain associated with ST-segment
depression and increased QRS duration. As the patients continued
walking, anginal pain disappeared and a concomitant lessening in
ST-segment depression and QRS prolongation was observed. Thus, the fact
that the onset of angina was associated with ST-segment depression and
prolonged QRS duration, while the disappearance of angina was associated
with a decrease in ST-segment depression and QRS prolongation, is
indicative of the effect of exercise-induced myocardial ischemia on QRS
duration.
