Exercise echocardiography: detection of wall motion abnormalities during ischemia.
To assess the feasibility of detecting wall motion abnormalities with echocardiography during exercise-induced ischemia, we performed echocardiograms on 13 patients with angiographically documented coronary artery disease at rest and during supine bicycle exercise at increasing work loads until angina or ischemic electrocardiographic changes appeared. We analyzed echocardiographic indices of re...
متن کاملDynamic exercise echocardiography.
To evaluate left ventricular (LV) reserve, we developed a method of dynamic exercise echocardiography (DEE). Forty-six healthy persons and 47 cardiac patients performed bicycle ergometer exercise in the supine position. A special table was used on which the subjects could be firmly attached at shoulder level to prevent bodily movements which might disturb the recordings. In 83% of the subjects ...

متن کاملLeft ventricular torsion during exercise in patients with and without ischemic response to exercise echocardiography.
INTRODUCTION AND OBJECTIVES Left ventricular torsion decreases during transmural myocardial ischemia, but the effect of exercise on left ventricular torsion has not been widely studied. We hypothesized that exercise-induced ischemia may impair left ventricular torsion. Therefore, our aim was to study the effects of exercise on left ventricular torsion in patients with an ischemic response to ex...
متن کاملClinical applications of exercise stress echocardiography in the treadmill with upright evaluation during and after exercise
Exercise stress echocardiography is the most frequently used stress test in our laboratory. Exercise echocardiography is used mainly in the study of patients with coronary artery disease. However, the technique is increasingly being used to study other diseases. In our centre, we use an original methodology, published by us in 2000, in which we evaluate heart function during exercise in the tre...
