Example of a left atrial strain (LAS) curve (yellow line). The x axis is time, and the y axis represents strain as a percentage. The ECG recording is shown in green for reference. The zero-strain reference is set at end-diastole. Dashed white lines represent strain values at end-diastole (0), end-systole, and the beginning of atrial contraction. Red arrows demonstrate the left atrial strain components. LASr, left atrial reservoir phase; LAScd, left atrial conduit phase; LASct, left atrial contraction phase
