摘要: Pulmonary venous flow has two phases (systolic and diastolic) in normal subjects when studied by pulsed Doppler echocardiography. Only one phase of pulmonary (diastolic) was observed six patients without synchronous atrial contraction (four with fibrillation complete atrioventricular [AV] block). This pattern reversed to (biphasic) AV synchrony reestablished cardioversion sinus rhythm sequential pacing block. Thus, both ventricular relaxation are important determinants flow.
