Multi-electrode panel system for sensing electrical activity of the heart
First Claim
1. An sensing system for use diagnosing and/or treating a heart of a patient, the patient having a torso surface, the sensing system comprising:
- an array of sensors for sensing heart cycle signals;
four sensor support panels having inner panel surfaces adapted for engaging the torso surface, the four panels supporting a majority of the sensors of the array in operative association with the torso surface when the panels engage the torso surface.

Abstract
Improved systems, devices, and methods sense heart signals through a torso surface of a patient. These improved systems facilitate mounting of an array of sensors upon the patient'"'"'s torso by supporting the sensor arrays on one or more panels. Four separate panels can be adapted for engaging the torso surface, with the four panels supporting most and/or all of the sensors necessary for localizing an arrhythmia within a chamber of a heart of a patient. The panels may have integrated components for use with other electrophysiology lab equipment such as cardiac imagers, defibrillation power sources, therapeutic probes, standard 12-lead electrocardiogram (ECG) systems, and the like. An exemplary arrhythmia sensing system is adapted for use in the high-noise environment of an electrophysiology lab includes a series of powered circuits distributed among the electrodes of the array. A separate low-noise environment sensing system may initially record an abnormal irregular or regular heartbeat outside the electrophysiology lab.
