Demonstration of LA and RV strain analysis using 2-dimensional speckle-tracking echocardiography (A). LA strain and illustration of the 3 phases of LA function with an R-R gating analysis. RV longitudinal strain calculated as the average of the six-segment model (B). ECG, electrocardiography; LA, left atrium; PACS, peak atrial contraction strain; PALS, peak atrial longitudinal strain; RV, right ventricular
