研究组 & 干预措施
left ventricular epicardial pacing lead
Enrolled patients will have a temporary left ventricular epicardial pacing lead placed in addition to the standard right ventricular and right atrial temporary epicardial pacing leads after open cardiac chamber cardiac surgery.
干预措施: left ventricular epicardial pacing lead (Other)
结局指标
主要结局
Right ventricular function of the heart
时间窗: 24 hours after cardiac surgery completion
Right Ventricular function is evaluated through combined echocardiographic interventricular synchrony variables which include pulmonary artery catheter derived cardiac index, pulmonary artery (PA) pressure, central venous pressure (CVP), CVP versus PA diastolic pressure, and systolic blood pressure.
