Left Atrium by Echocardiography in Clinical Practice: From Conventional Methods to New Echocardiographic Techniques
Figure 5
Left atrial strain (a) and strain rate (b) curves by Doppler. Left atrial reservoir function is studied by peak systolic value (ball), left atrial conduit function by peak early diastolic value (square), and left atrial pump function by peak late diastolic value (triangle).
