Abstract
The intraventricular conduction time was measured during rest, exercise, and recovery in five patients who developed acute left anterior hemiblock during exercise-induced myocardial ischemia. The AQRS shifted from 58 ± 17° at rest to -66 ± 11° during exercise (p<0.001). The intraventricular conduction time at rest was 86 ± 4 ms and increased to only 90 ± 4 ms during left anterior hemiblock. Our observations suggest that the intraventricular conduction time is not always prolonged during left anterior hemiblock, particularly if this conduction abnormality is acute.
