Two-dimensional speckle-tracking echocardiographic assessment of atrial function. Measurement of left atrial (A) and right atrial (B) reservoir, conduit and contractile function by strain and strain rate curves. LA left atrial, RA right atrial, Sr strain during the reservoir phase, Scd strain during the conduit phase, Sct strain during the contractile phase, pSRr peak strain rate during the reservoir phase, pSRcd peak strain rate during the conduit phase, pSRct peak strain rate during the contractile phase
