Evaluation of exercise performance in mitral stenosis using Doppler echocardiography,ted by exertion, it is important that hemodynamic performance be assessed both at rest and during some form of stress, such as muscular exercise, pharmacologic intervention or artificially induced tachycardia. This kind of evaluation enables one to assess both the severity of hemodynamic impairment

Left ventricular ejection force and impulse: Noninvasive assessment using Doppler ultrasound, recently . In 1964, Rushmer concluded that the left ventricle acts as an impulse generator and that the ‘initial ventricular impulse’ represents a reliable index of myocardial performance. Based on this concept, Rushmer suggested the use of measurement of peak aortic blood velocity and acc

Theoretical analysis of the left ventricular ejection pulse,ak velocity, stroke integral, and the systolic time intervals all key upon features of the flow profile easily measured in hard copy records. Clinical evaluations have been restricted to correlative studies evaluating pulse timing, rate of rise, and peak deflection with commonly accepted invasive an

Practical considerations in Doppler stress testing,re not discussed. It is the purpose of this chapter to orient the beginner to equipment, stress testing protocols, details of patient study, discrimination of good and bad data, and data analysis. With these issues in mind, it should be possible for novices to confidently approach patients in the stress testing laboratory.
