Patent ID: 8649852

Claim:
A method of monitoring cardiac electrical activity, comprising: requesting a first cardiac electrical signal from a first ECG device, the first ECG device comprising a first pair of electrodes positioned on longitudinally opposing ends of said first ECG device, wherein a first electrode of the first pair of electrodes is positioned at a location of maximum electrical potential for a first predetermined ECG signal; and a second electrode of the first pair of electrodes is positioned along a first equipotential line extending from the location of maximum electrical potential for the first predetermined ECG signal; receiving the first cardiac electrical signal; requesting a second cardiac electrical signal from a second ECG device, the second ECG device comprising a second pair of electrodes positioned on longitudinally opposing ends of said second ECG device, wherein a first electrode of the second pair of electrodes is positioned at a location of minimum electrical potential for the first predetermined ECG signal; and a second electrode of the second pair of electrodes is positioned along a second equipotential line extending from the location of minimum electrical potential for the first predetermined ECG signal; receiving the second cardiac electrical signal; and computing an enhanced cardiac electrical signal based on the first and second cardiac signals, the enhanced cardiac electrical signal representing a larger electrical potential difference than either the electrical potential difference between the first pair of electrodes or the electrical potential difference between the second pair of electrodes.
