ABSTRACT:
A single-pass A-V lead for cardiac pacing comprises a lead body having an atrial electrode and a right ventricular outflow tract (RVOT) electrode. Preformed bends in the lead body are configured such that the atrial and RVOT electrodes are biased against walls of the right atrium and the RVOT respectively. Biasing forces generated by the preformed bends help to maintain the atrial and RVOT electrodes in their respective positions following implantation. The lead advantageously permits ventricular stimulation in the RVOT, resulting in an improved sequence of ventricular activation and a corresponding increase in cardiac output. Branched and unbranched embodiments of the lead are disclosed.
