A comprehensive two-dimensional echocardiographic examination provides useful information that is superior to MT-mode regarding left ventricular chamber sizes and systolic performance, including ejection fraction. Although we rely on visual estimates, quantitative measurements can be particularly valuable in patients with mild or moderate left ventricular systolic dysfunction. Measurements of left ventricular mass by two-dimensional echocardiography is supenror to Ml-mode to detect left ventricular hypertrophy. Two-dimensional echocardiography combined with pulsed Doppler echocardiography can be used to accurately measure stroke volume and to assess changes during medical therapy or after interventions. Future work is needed to assess the significance of continuous-wave Doppler-derived rate of pressure change in patients with mitral regurgitation.

Key Words: two-dimensional echocardiography • pulsed and continuous-wave Doppler • left ventricular systolic function
