1 Clinical Trials for Various Conditions
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
