1. An implantable defibrillation lead, comprising:
- a lead body including a distal portion terminated by a distal tip, the distal tip including a fixation element coupled thereto, the fixation element adapted to couple the lead to an endocardial surface of a right ventricle;
a defibrillation electrode coupled to the distal portion of the lead body and positioned along the distal portion of the lead body such that a portion of the electrode being located in proximity to a right ventricular apex when the fixation element couples the lead to the endocardial surface; and
a physiological sensor adapted to function in a high flow region of a circulatory system coupled to the distal portion of the lead body for sensing signals other than cardiac electrical signals, the sensor positioned along the distal portion of the lead body such that the sensor being located in a high flow region of the right ventricle and spaced apart from the endocardial surface when the fixation element couples the lead to the endocardial surface.

Abstract
An implantable lead includes a defibrillation electrode and a sensor coupled thereto. The electrode and sensor are positioned along a body of the lead such that, when a fixation element couples the lead to an endocardial surface of a right ventricle, the sensor is located in a high flow region and a portion of the defibrillation electrode is located in proximity to a right ventricular apex.
