Abstract:

This disclosure describes implantable medical leads and medical device systems utilizing the leads. In some examples, an implantable medical lead comprises a first defibrillation electrode and a second defibrillation electrode, the first and second defibrillation electrodes configured to deliver anti-tachyarrhythmia shocks, and a pace electrode disposed between the first defibrillation electrode and the second defibrillation electrode, the pace electrode configured to deliver a pacing pulse that generates an electric field proximate to the pace electrode. The implantable medical lead further comprises a shield disposed between the first defibrillation electrode and the second defibrillation electrode and over a portion of an outer surface of the pace electrode, wherein the shield is configured to impede the electric field in a direction from the pace electrode away from a heart.
