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.
Claims20
An apparatus configured for implantation within a body of a patient, the apparatus comprising:
- a housing including circuitry configured to sense an electrocardiogram (ECG) signal from a cardiac electrical field;
- at least three antennas extending from the housing, including a first antenna, a second antenna, and a third antenna, the first, second, and third antennas being flexible such that the first, second, and third antennas conform to the body of the patient;
- and
- at least three electrodes including at least a first electrode, a second electrode, and a third electrode, wherein at least the first electrode is disposed on the first antenna and at least the second electrode is disposed on the second antenna, wherein at least the first, second, and third electrodes are disposed in a non-linear configuration and provide at least three vectors of the cardiac electrical field, the at least three vectors being configured to sense the ECG signal, wherein the first, second, and third antennas correspond to first, second, and third axes, respectively, of a surrogate coordinate system, wherein the apparatus is configured to determine and map, with respect to the surrogate coordinate system, one or more of the at least three vectors of the cardiac electrical field.
