Abstract
Speckle tracking echocardiography (STE) is an imaging\ud technique applied to the analysis of left atrial function. STE\ud provides a non-Doppler, angle-independent and objective\ud quantification of left atrial myocardial deformation. Data\ud regarding feasibility, accuracy and clinical applications of\ud left atrial strain are rapidly gathering. This review describes\ud the fundamental concepts of left atrial STE, illustrates its\ud pathophysiological background and discusses its emerging\ud role in systemic arterial hypertension
