METHOD AND SYSTEM FOR GENERATING TWELVE-LEAD ELECTROCARDIOGRAM SIGNALS USING THREE DIFFERENTIAL VOLTAGES
First Claim
1. A method of generating twelve-lead electrocardiogram (ECG) signals to be implemented by a signal processor, said method comprising the steps of:
- a) receiving three differential voltages, each of which is defined as a potential difference between two corresponding myoelectric signals sensed respectively by two corresponding electrodes that cooperatively constitute a corresponding differential electrode pair that are disposed on a chest of a user'"'"'s body at predetermined specific locations; and
b) generating, based on the differential voltages, the twelve-lead ECG signals, which include twelve synthesized lead signals, using a pre-established dynamic system model that is associated with the specific locations of the electrodes constituting the differential electrode pairs on the chest of the user'"'"'s body and that is configured with temporal and spatial correlations among twelve leads of an ECG, which include eight independent leads and four non-independent leads.

Abstract
In a method and system for generating twelve-lead ECG signals based on three differential voltages, each of which is defined as a potential difference between two myoelectric signals sensed respectively by two corresponding electrodes that cooperatively constitute a corresponding differential electrode pair and that are disposed on a user'"'"'s chest at predetermined specific locations, a signal processor generates the twelve-lead ECG signals using a pre-established dynamic system model that is associated with the specific locations of the electrodes on the user'"'"'s chest and that is configured with temporal and spatial correlations among twelve leads of an ECG.
