心房总传导时间是心房颤动的独立危险因素，PA－TDI间期作为新的心房总传导时间评价指标，近来引起广泛的研究。其与金标准平均信号心电图高度相关，受到心房内传导速度和心房体积的影响，正常值范围有待进一步研究确认，临床上能一定程度预测心房颤动发生风险。

Total atrial conduction time ( TACT) is an independent risk factor for atrial fibrillation.Tissue Doppler imaging ( PA-TDI Interval) was a non-invasive test created to measure TACT and assist with an accurate diagnosis.The results of PA-TDI interval studies are highly correlated to those of the signal-averaged electrocardiogram, which has been considered the gold standard.The PT-TDI interval is in-fluenced by atrial size and conduction velocity, making a normal value uncertain.This review examines the current research being done on PT-TDI interval in relation to TACT and the creation of a normal range to aid in the prediction of atrial fibrillation.
