1. A method of treating a heart, comprising:
- providing an electrode and sensor assembly including one or more electrodes, a pressure sensor and a pressure transmission catheter; and
positioning the electrode and sensor assembly proximate an outside surface of the heart such that the one or more electrodes reside on or in a wall of the heart, and the pressure transmission catheter is exposed to a heart chamber to provide fluid communication between the heart chamber and the pressure sensor.

Abstract
Devices and methods for left ventricular or biventricular pacing plus left ventricular pressure measurement. For example, a pacing lead having a combined electrode and pressure sensor assembly may be used for left ventricular (LV) pacing and pressure measurement. The assembly may include one or more electrodes, a pressure sensor, and a pressure transmission catheter. Such a pacing lead is particularly suitable for biventricular pacing and may be incorporated into a cardiac resynchronization therapy (CRT) system, for example.
