Dependence of disoder of contractility of the left ventricle of patients with total blockade of the left peduncle of the bundle of his on age factor

48 patients from 100 with total blockade of the left peduncle of the bundle of His and with sinus rhythm had a normal fraction ejection (FE) and 52 patients didn't have it. 94,2% of patients in the group with reduced FE and 85,5% of patients in the group with normal FE of the left ventricle were patients of the second period of mature age and the elderly age.
