Abstract
A medical device includes multiple electrodes and a processor. The multiple electrodes are coupled to a substrate attached externally to a patient and are configured to sense multiple respective electrical signals from an organ of the patient. The processor is configured to estimate two or more noise levels associated with the electrical signals sensed by two or more respective pairs of the electrodes, to select the electrical signals having a smallest noise level from among the two or more noise levels, and to provide only the selected electrical signals for analysis.
Claims22
A medical device, comprising:
- a patch having multiple electrodes coupled to a substrate attached externally to a patient, the multiple electrodes being configured to sense multiple respective electrical signals from an organ of the patient, the multiple electrodes including a plurality of pairs of electrodes, each pair of electrodes lying on an axis of the patch in the plane of the substrate different from the axis of every other pair of electrodes;
- and
- a processor, which is configured to:
- estimate noise levels associated with the electrical signals sensed by the plurality of pairs of electrodes;
- select a pair of electrodes of the plurality of pairs of electrodes having two electrical signals with a smallest noise level from among the estimated noise levels;
- and
- provide only the two electrical signals from the selected pair of electrodes for analysis.
