Biventricular Epicardial Pacing Post Cardiac Surgery in Patients With Left Ventricular Ejection Fractions Less Than 45%

Patients with reduced left ventricular function are at an increased perioperative risk and often need prolonged postoperative treatment on intensive care units. A significant portion of these patients require postoperative pacing. Right ventricular pacing has been shown to be hemodynamically deleterious The aim of this study is to determine which biventricular pacing after cardiac surgery, in patients with reduced left ventricular function (EF≤ 45%), is hemodynamically favourable.
