本文应用三尖瓣多普勒频谱方法,研究各种右室负荷状态的先心病右室舒张功能的变化。观察到右室压力负荷过重患者舒张早期与晚期右室充盈指标均有显著改变,右室容量负荷过重者以舒张晚期功能异常为主,而右室尚未出现负荷过重的先心病也存在右室舒张功能异常现象。
In this paper, tricuspid valve Doppler spectrum method to study a variety of right ventricular load conditions of right ventricular diastolic function changes. The patients with right ventricular pressure overload were observed in patients with early and late diastolic early filling index significantly changed, right ventricular volume overload over late diastolic dysfunction, while the right ventricle has not yet overloaded congenital heart disease also exist Right ventricular diastolic dysfunction.
