  • Method of signal enhancement for ECG devices
    Patent number: 9486150
    Abstract: An embodiment of the invention comprises a method of monitoring cardiac electrical activity with two or more ECG devices and computing an enhanced cardiac electrical signal from the cardiac electrical signals obtained from the two or more ECG devices. Electrodes of the two or more ECG devices are positioned in a manner to provide an electrical potential difference that is large enough to give useful information about a given ECG signal. The method further includes recommending addition of a supplemental ECG device when it is determined that the one or more of the existing ECG devices are inadequate for providing cardiac electrical data that identifies a specific cardiac event.
    Type: Grant
