Figure 3From: Left atrial longitudinal strain by speckle tracking echocardiography correlates well with left ventricular filling pressures in patients with heart failure Correlation between global peak atrial longitudinal strain (PALS) and mean E/Em ratio. R = 0.1487; p = ns. (PALS, peak atrial longitudinal strain; E, early transmitral flow velocity; Em, early diastolic mitral annular velocity).Back to article page
