Figure 1From: Left atrial longitudinal strain by speckle tracking echocardiography correlates well with left ventricular filling pressures in patients with heart failure Measurement of peak atrial longitudinal strain (PALS) from an apical two-chamber view. The dashed curve represents the average atrial longitudinal strain along the cardiac cycle. (PALS, peak atrial longitudinal strain; AVC, aortic valve closure).Back to article page
