[Transitory left deviation in the electrical axis of QRS during an exercise test as a manifestation of a severe proximal lesion of the descending anterior artery].
The case of a patient in whom transient left axis deviation occurred during a treadmill exercise test is reported. Coronary angiography showed a 90% obstruction of the proximal left anterior descending artery. After a successful coronary angioplasty and stent implantation, a control exercise test was performed without a recurrence of angina or transient intraventricular conduction disturbance, reflecting the ischaemic nature of this abnormality.
