[Hemodynamic changes in ischemic heart disease with disordered intraventricular conduction]

Cardiac output, blood volume and velocity of blood flow were studied in 30 patients with ischemic heart disease with intraventricular conductivity. Thirty patients with ischemic heart disease without disturbances of conductivity and 30 healthy subjects were used as a control group. Decreased heart stroke volume and blood flow velocity in pulmonary circulation were found in the patients with left bundle block. In the patients with right bundle block--changes in blood volume, heart rate and velocity of blood flow in systemic circulation were established. The type of conductivity disturbances in patients with ischemic heart disease was concluded to be dependent on stage and type of hemodynamic disturbances.
