Exercise Doppler cardiography,gh Bousfield was the first to detect ECG changes during stress in 1918 [1], Master and Jaffe [2] introduced this idea as a diagnostic tool in 1941. Since then this technique has been in increasing use, with modifications, in order to increase its value for the diagnosis of coronary artery disease. I

Quantitative evaluation of aortic and mitral stenosis by continuous wave Doppler echocardiography,ese techniques, the clinician can reliably identify the presence of abnormal valvular structure and indirectly demonstrate its hemodynamic significance through chamber enlargement or hypertrophy. However, neither technique can measure actual pressure gradients across stenotic valves and because of t

A new approach to noninvasive estimation of stenotic orifice area in semilunar valve stenosis by Dovalve [1–9]. Although the pressure gradient is a practically useful parameter to evaluate the severity of stenotic valve lesions, it essentially depends on flow rate. For a given stenotic orifice, it may vary with the changes in the hemodynamic state of the heart, and not be simply regarded as an ab

Orchiectomy

Evaluation of left ventricular diastolic filling by a pulse Doppler flowmeter in patients with coroe of changes in LV volume is used for the assessment of LV diastolic filling. However, in CAD, the calculation of LV volume is sometimes difficult because of the regional abnormalities of LV wall motion. The transmitral blood flow during diastole is equal to the rate of changes in LV volume in the a
