Figure 1. Representative left atrial strain images.

Figure 1

Y-axis = longitudinal strain (%). X-axis = time (ms). Note: each graph has different range for the Y-axis. LA booster strain is not present in the setting of AF. LA conduit strain = LA reservoir strain – LA booster strain. In AF, LA reservoir strain = LA conduit strain.

LA = left atrial; HFpEF = heart failure with preserved ejection fraction; NSR = normal sinus rhythm; AF = atrial fibrillation.
