The image depicts 2D speckle-tracking echocardiography of the right atrium in the modified apical 4-chamber view. A strain curves, B strain rate curves. pRASRcd, peak right atrial longitudinal strain rate during the conduit phase; pRASRct peak right atrial longitudinal strain rate during the contraction phase, pRASRr peak right atrial longitudinal strain rate during the reservoir phase, RAScd right atrial longitudinal strain during the conduit phase, RASct right atrial longitudinal strain during the contraction phase, RASr right atrial longitudinal strain during the reservoir phase
