We evaluated 39 patients >45 years old with paroxysmal supraventricular tac
hycardia (SVT), 21 of whom had ST-segment depression during SVT. Treadmill
exercise testing, including thallium stress scintigraphy, was performed in
all patients and coronary angiography in 21 patients with ST-segment depres
sion. Based on the presence of abnormal findings on exercise electrocardiog
ram and/or thallium in 7 of 21 patients (33%) with ST-segment depression, w
ith additional corroboration by angiographic data, we conclude that myocard
ial ischemia and coronary artery disease is one, but not the only, mechanis
m involved in the genesis of ST-segment depression during paroxysmal SVT.
