Doppler echocardiography enables convenient, noninvasive evaluation of global, systolic
performance at rest and during exercise. Early studies suggested that Doppler parameters of …

Exercise testing is commonly used in both the diagnosis of coronary artery disease and in
assessment of its physiological significance. Stress electrocardiography has a diagnostic …

Doppler echocardiography in the 1980's has become one of the cornerstones of
noninvasive testing in the evaluation of valvular heart disease. Because more of the …

Doppler echocardiography is a useful noninvasive determination of left ventricular function
during dynamic exercise. Scarce data are available for the use of this technique during …

To evaluate the clinical usefulness of Doppler-derived cardiac output and the effect of
altered left ventricular function during maximal treadmill exercise, this study was performed …

Systolic and especially diastolic Doppler time intervals may be early markers of myocardial
ischemia inducible by dobutamine-atropine stress echocardiography (DASE). We postulated …

Recent advances in Doppler echocardiography have made possible noninvasive
determination of stroke volume, cardiac output and peak ejection velocity at rest. To …

It has been over a decade since the initial studies confirming that transcutaneous Doppler
ultrasound could be used to accurately assess ascending aortic blood flow velocities [1–3] …

Perhaps the most serious intervention a cardiologist can recommend to patients under his
care is cardiac surgery. Doppler ultrasound has proven merit in identifying patients with …

Background Pulsed-wave Doppler assessment of myocardial velocity (MDV) may permit a
more quantitative interpretation of stress echocardiography. This technique has been used …
