This article discusses the traditional and more recent echocardiographic measures that have been employed to evaluate atrial function. Conventional parameters commonly used and reported in the literature include the study of the various phases of atrial activity using atrial volume measurements, the peak A wave velocity, its velocity time integral (VTI) and the fraction of atrial contribution (all obtained from transmitral flow), as also the atrial ejection force. Newer parameters for atrial function assessment include Doppler tissue imaging (DTI) including segmental atrial contractility using colour Doppler tissue imaging (CDTI) and estimates of atrial strain and strain rate.
本文讨论了用于评估心房功能的传统及最新超声心动图测量方法。文献中常用和报道的传统参数包括：通过心房容积测量研究心房活动的各个阶段、A波峰值速度、其速度时间积分（VTI）以及心房贡献分数（均从二尖瓣血流中获取），还有心房射血力。评估心房功能的较新参数包括多普勒组织成像（DTI），其中包括使用彩色多普勒组织成像（CDTI）评估节段性心房收缩力以及心房应变和应变率的估计值。
