Summary

This study evaluates the usefulness of 3D echocardiography to guide pacemaker therapy in the operating room in cardiac surgical patients. Each patient will serve as his own control, following a paired design.

Conditions

  • Disorder of Pacing Function

Interventions

DEVICE

Right ventricular epicardial pacing

The patient's own heart rate at that moment will be the starting point for the study. Right ventricle pacing will be instituted by selecting a rate that is 5 beats above the patient's own heart rate. We will use a stepwise approach where we increase the pacermaker's rate with steps of 5 beats until we have 100% capture of the pacemaker beats. After waiting for at least one minute of pacing we will obtain a set of measurements.

PROCEDURE

cardiac surgery

Elective cardiac surgery, with use of cardiopulmonary bypass.

DEVICE

3D TEE

Intraoperatively, all patients will be monitored by means of TEE

DEVICE

Pacemaker lead

All patients will have a epicardial pacemaker lead in situ.
