Effects of age and gender upon Doppler stress measurements at rest and during exercise in normal su females. Heart rate and loading conditions have also been documented to be related to cardiac chamber dimensions . The purpose of this chapter is to assess in normal subjects the relationships, during both rest and exercise, between Doppler systolic flow velocity measurements and age, gender, and body surface area.

Exercise Doppler in coronary artery disease: Correlation with thallium-201 perfusion scintigraphy,ternal Doppler aortic blood flow measurements during treadmill exercise testing in a large population of normal patients and compare stress Doppler results to thallium-201 scintigraphy in a cohort of patients referred for evaluation of suspected or known coronary artery disease.

Assessment of the effect of coronary artery bypass grafting on left ventricular function by stress 7, 8] or no improvement or even deterioration . Some of the factors which have led to such mixed reports are the techniques used in the evaluation, the timing of te postoperative assessment and finally whether the assessment was carried out at rest or during exercise.

Evaluation of exercise performance in mitral stenosis using Doppler echocardiography,patients for surgery and predicting prognosis. Since the stress of muscular exercise closely resembles the life situation in which the patient with heart disease may become symptomatic, exercise is commonly used in the evaluation of patients with heart disease.

Left ventricular ejection force and impulse: Noninvasive assessment using Doppler ultrasound,n is closely related to the maximum force exerted by the left ventricle in early systole and directed towards overcoming inertia. The force is a well established physical term defined as the product of mass and acceleration according to Newton’s second law of motion: Force = mass × acceleration

The left ventricular impulse,s have converted cardiology from a highly subjective clinical discipline into a more comprehensive and quantitative analysis of the human circulation as a hydraulic system. The significance of this profound change is more readily appreciated by comparing current concepts with the generally accepted tenets of the recent past.

Effect of preload, afterload, and inotropic state on Doppler ejection dynamics,ly related to left ventricular function to be effected in a characteristic fashion by myocardial ischemia and infarction and by interventions such as the administration of catecholamines and propranolol .

Theoretical analysis of the left ventricular ejection pulse,d noninvasive reference standards of ventricular performance; dP/dt, ejection fraction, Vcf, and power of left ventricular ejection. Ischemic mass, extent of coronary disease, exercise tolerance, and thallium perfusion defects have also been referenced. No prior study has addressed the genesis of the flow pulse in the ascending aorta.
