Bifocal pacing in the right ventricle: an alternative to resynchronization when left ventricular access is not possible in end-stage heart failure patients.

Background: It has been reported that bifocal pacing (BiF) in the right ventricle might be an alternative to unsuccessful left ventricular lead implantation. This case report presents an assessment of the clinical and hemodynamic parameters during a three month follow-up in patients implanted with right ventricular BiF.

Methods: Eight patients who underwent unsuccessful left ventricular lead implantation were implanted with a bifocal system in the right ventricular.
