Figure 1

a . Echocardiographic image showing the apical four-chamber view in a subject of the control group. The image shows the myocardial velocity profile obtained in the basal segment of the left ventricular lateral wall. The time intervals identified by figures indicate: 1 = Electromechanical delay time (EMDT); 2 = Isovolumic contraction time (IVCT); 3 = Electro hemodynamic delay time (EHDT); 4 = Ejection time (ET); 5 = Isovolumic relaxation time (IVRT). A' = Late diastolic (A-wave) velocity); E' = Early (E-wave) diastolic velocity; PSV = Peak systolic velocity. b, represent the same image in a patient with isolated LBBB; c in a patient with dilated cardiomyopathy and LBBB; d in a patient with ischemic cardiomyopathy and LBBB.
