ABSTRACT:
The present invention provides a pacing system with a lead having a fixation element for providing stable fixation relative to the patient's SVC, preferably providing for positioning of the atrial electrodes near the sinus node. In a first embodiment, an adjustable loop is provided for engaging the inside wall of the SVC so as to obtain fixation of the lead just above the sinus node. Other embodiments utilize tine arrangements for providing the fixation relative to the SVC.
