Fig. 2From: Epicardial adipose tissue thickness is related to early subclinical myocardial dysfunction, particularly in patients with type 2 diabetes mellitus: a case control studyStrain measurement. Tissue Doppler echocardiography, strain rate, and strain profiles of a normal subject obtained from an apical four chamber view. Time is on the X-axis. The waveform consists of a first positive wave (pre-ejection period), followed by the isovolumic relaxation waves. Longitudinal strain rate profile is obtained from the same region of interest during the same cardiac cycleBack to article page
