About

The purpose of this study is to:

1. assess the existence of inter-ventricular and intra-ventricular asynchrony in cardiac surgery patients before (PRE) and after cardiopulmonary bypass surgery (POST)
2. investigate whether a modification of usual pacing practices (RA-LV pacing) can achieve inter- and intra-ventricular synchrony and improve heart function, as evaluated by hemodynamic and echocardiographic indexes, when compared with the patient's native rhythm (normal sinus rhythm (SR), or conventional pacing modes

Enrollment: 20 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• scheduled for cardiac surgery, in normal sinus rhythm

Exclusion criteria

• atrial fibrillation, abnormal hearth rhythms
