Adherent Cardiac Monitor with Advanced Sensing Capabilities
First Claim
1. A method of monitoring a patient, the method comprising:
- adhering an adherent device to a skin of the patient, the adherent device comprising an accelerometer and at least two measurement electrodes, the at least two measurement electrodes separated by a distance to define an electrode measurement axis;
measuring an accelerometer signal when the device is adhered to the patient; and
determining an orientation of the electrode measurement axis on the patient in response to the accelerometer signal.

Abstract
An adherent device comprises an adhesive patch with at least two electrodes and an accelerometer. The accelerometer can be used to determine an orientation of the at least two measurement electrodes on a patient. By determining the orientation of the electrodes of the patch on the patient, physiologic measurements with the at least two electrodes can be adjusted and/or corrected in response to the orientation of the patch on the patient. The adherent patch and/or electrodes can be replaced with a second adherent patch and/or electrodes, and the orientation of the second adherent patch and/or electrodes can be determined with the accelerometer or a second accelerometer. The determined orientation of the second patch and/or electrodes on the patient can be used to correct measurements made with the second adherent patch and/or electrodes.
