Objectives To observe the variability of which variation of normal subjects short-axis of the left ventricular subendocardial and subepicardial layers myocardial circumferential strain during isovolumic end-diastolic in the exercise stress, and to analyse the differences of the different myocardial layers strain. Methods Echocardiography was performed in 43 healthy students at rest, maximal aerobic power and recovery after exercise. Store the dynamic images of the left ventricular basal, papillary muscle E296 Heart 2012;98(Suppl 2): E1-E319
