This article describes four essential components (hemodynamic, bioelectrical, hormonal and metabolic) of atrial function. And then discusses the traditional and more recent echocardiographic measures that have been employed to evaluate atrial function. Conventional parameters include the study of the various phases of atrial activity using atrial volume measurements, the peak A wave velocity, its velocity time integral (VTI), fraction of atrial contribution and atrial ejection force. Newer parameters for atrial function assessment include Doppler tissue imaging (DTI) including segmental atrial contractility using color Doppler tissue imaging (CDTI) and estimates of atrial strain and strain rate. Furthermore, the authors relate various particular types of atrial function in physiological and in selected pathological conditions.
