Apparatus and method for electrocardiographic monitoring
First Claim
1. An apparatus configured for implantation within a body of a patient, the apparatus comprising:
- a housing;
at least two antennas extending from the housing, including a first antenna and a second antenna, the first and second antennas being flexible such that the first and second antennas conform to the body of the patient;
at least three electrodes, wherein at least a first electrode is disposed on the first antenna, at least a second electrode is disposed on the housing, and at least a third electrode is disposed on the second antenna, wherein the first, second, and third electrodes are disposed in a non-linear configuration and provide at least three vectors along which to sense an electrocardiogram (ECG) signal; and
circuitry configured to use the at least three vectors to gain or subtract a first portion of the ECG signal and amplify a remaining second portion of the ECG signal.

Abstract
In various examples, an apparatus includes an apparatus configured for implantation within a body of a patient. The apparatus, in some examples, includes a housing. At least one antenna extends from the housing, the antenna being flexible such that the antenna conforms to the body of the patient. In some examples, the apparatus includes at least three electrodes, wherein at least a first electrode is disposed on the antenna and at least a second electrode is disposed on the housing. The at least three electrodes are disposed in a non-linear configuration, allowing for differential processing of signals recorded by the at least three electrodes.
