Ee. Esteban et al., EXERCISE-INDUCED LEFT AXIS SHIFT AS A MAR KER OF PROXIMAL LEFT ANTERIOR DESCENDING CORONARY-ARTERY DISEASE, Revista espanola de cardiologia, 50(7), 1997, pp. 535-538
The case of a patient in whom transient left axis deviation occurred d
uring a treadmill exercise test is reported. Coronary angiography show
ed a 90% obstruction of the proximal left anterior descending artery.
After a successful coronary angioplasty and stent implantation, a cont
rol exercise test was performed without a recurrence of angina or tran
sient intraventricular conduction disturbance, reflecting the ischaemi
c nature of this abnormality.
