<p>The present invention provides a cardiac pacing system with a DDD lead 10 with pre-stressed curvilinear portions, the lead being able to adapt to heart movement and size so as to provide more stable positioning with respect to the atrium. The lead has at least three such pre-stressed curvilinear portions 34, 30, 26 positioned to adapt to the patient's heart and to absorb movement due to contractions so as to maintain atrial electrodes in a stable position with respect to the atrial wall. <IMAGE></p> |
