本研究评估了二尖瓣环速度在评估房颤患者左心室舒张功能中的临床效用。心房颤动是临床实践中最常见的持续性心律失常。由于左心房压力的改变和同步心房收缩的丧失，传统多普勒指数的临床用途在心房颤动中受到限制。仅在心导管实验室对 27 名非风湿性心房颤动患者的二尖瓣流入和二尖瓣环速度与 tau 蛋白同时进行测量。在二尖瓣流入减速时间、二尖瓣流入峰值速度 (E) 和舒张期二尖瓣环峰值速度 (E') 中，只有 E' 与 tau 相关 (r = 0.51，P = .007)。 E' 可以预测 tau 延长（大于或等于 50 ms）
This study assessed the clinical utility of mitral annulus velocity in the evaluation of left ventricular diastolic function Ln patients with atrial fibrillation. Atrial fibrillation is the most common sustained arrhythmia encountered in, clinical practice. The clinical usefulness of conventional Doppler indexes is limited in atrial fibrillation because of the altered left atrial pressure and loss of synchronized atrial contraction. Mitral inflow and mitral annulus velocities mere measured simultaneously with tau in 27 patients with nonrheumatic atrial fibrillation at the cardiac catheterization laboratory. Among deceleration time of mitral inflow, peak mitral inflow velocity (E), and peak diastolic mitral annulus velocity (E'), only E' correlated with tau (r = 0.51, P = .007). Prolonged tau (greater than or equal to 50 ms) could be predicted by E'
