Method and apparatus for enhancing cardiac pacing
First Claim
1. A method of enhancing cardiac pacing, the method comprising:
- measuring at least one characteristic of a heart using one or more parameter measuring devices disposed in the heart,calculating at least one cardiac performance parameter using the at least one measured characteristic;
accepting at least one command from a user, said command assigning a relative weight to said at least one cardiac performance parameter, andautomatically adjusting at least one functional parameter of a cardiac pacing device, wherein said adjusting comprises determining said adjustment to be made to the at least one functional parameter based on the at least one cardiac performance parameter and said assigned relative weight of said at least one cardiac performance parameter.

Abstract
Methods, apparatus and systems for enhancing cardiac pacing generally provide for measuring at least one cardiac characteristic, calculating at least one cardiac performance parameter based on the measured characteristic(s), and adjusting at least one functional parameter of a cardiac pacing device. Devices may include at least one catheter (such as a multiplexed catheter with one or more sensors and/or actuators), at least one implant (such as a sensor implantable in a heart wall), or a combination of both. Various cardiac performance parameters and/or pacing device performance parameters may be weighted, and the parameters and their respective weights may be used to determine one or more adjustments to be made to the pacing device. In some instances, the adjustments are made automatically.
