现在常用脉冲多普勒超声心动图描记二尖瓣血流速度,以此形式分析左心室舒张充盈情况及功能,但临床中的形式多种多样,还受到舒张早期充盈情况,如负荷条件、PQ或房室间期和二尖瓣返流等一系列因素的影响。弄清它们对早期舒张功能的影响对于利用二尖瓣血流速度形式分析左心室功能十分重要。本文旨在研究左心室功能和左心房压力在早期舒张充盈中的作用。
Now commonly used pulsed Doppler echocardiography mitral flow velocities, in this form of analysis of left ventricular diastolic filling situation and function, but the clinical form of a variety of, but also by early diastolic filling conditions, such as load conditions, PQ Or atrioventricular and mitral regurgitation and a series of other factors. Finding out their effect on early diastolic function is important for the analysis of left ventricular function using mitral flow velocities. This article aims to investigate the role of left ventricular function and left atrial pressure in early diastolic filling.
