This study describes a method for estimation of the ratio of pulmonary to systemic pressures by pulsed-wave Doppler echocardiography. Sixty-eight patients ages 1 day to 68 years who underwent cardiac catheterization had Doppler studies of the right and left ventricular outflows. Preejection period (...
