Implantable extravascular electrical stimulation lead having improved sensing and pacing capability
First Claim
1. A method comprising:
- detecting a tachyarrhythmia;
in response to detecting the tachyarrhythmia, delivering an antitachyarrhythmia shock via an implantable medical electrical lead comprising a defibrillation electrode that includes a first electrode segment and a second electrode segment spaced proximal to the first electrode segment by a distance, wherein delivering the tachyarrhythmia shock comprises selectively delivering the tachyarrhythmia shock via one of;
the first electrode segment and not the second electrode segment;
the second electrode segment and not the first electrode segment;
orboth the first electrode segment and the second electrode segment simultaneously; and
at least one of delivering cardiac pacing or sensing cardiac signals via at least one pace/sense electrode of the implantable medical electrical lead, the at least one pace/sense electrode located between the first segment and the second segment of the defibrillation electrode.

Abstract
Implantable medical electrical leads having electrodes arranged such that a defibrillation coil electrode and a pace/sense electrode(s) are concurrently positioned substantially over the ventricle when implanted as described. The leads include an elongated lead body having a distal portion and a proximal end, a connector at the proximal end of the lead body, a defibrillation electrode located along the distal portion of the lead body, wherein the defibrillation electrode includes a first electrode segment and a second electrode segment proximal to the first electrode segment by a distance. The leads may include at least one pace/sense electrode, which in some instances, is located between the first defibrillation electrode segment and the second defibrillation electrode segment.
