Patent ID: 8897861

Claim:
A modified electrocardiograph configured to record electrical activity of specific myocardial structures of a patient, the electrocardiograph comprising: a Common Positive Electrode that is adapted to be placed on an extremity of a patient, wherein the Common Positive Electrode is connected to a Common Positive Terminal; a plurality of amplifiers ( 1 , 2 , to n), n=15-100, wherein a positive terminal of each of the plurality of amplifiers is connected to the Common Positive Terminal and wherein a negative terminal of each of the plurality of amplifiers is connected to a corresponding Exploring Negative Electrode ( 1 , 2 , to n) that is adapted to be placed on a torso of the patient; a plurality of A/D converters ( 1 , 2 , to n), n=15-100, each connected to a respective one of said plurality of amplifiers, wherein said plurality of A/D convertors are connected to a microprocessor of the modified electrocardiograph, said microprocessor comprising: a first stage configured to receive signals from each of said Exploring Negative Electrodes and said Common Positive Electrode and is further configured to filter the received signals, thereby creating n-filtered digital data sets; a second stage comprising a programmed analyzer configured to select and pair minimum and maximal values of the n-filtered digital data sets at specific instants of an electrocardiographic trace and a calculator configured to subtract the minimum value from the maximal value of each pair of minimum and maximal values for each specific instant of the electrocardiographic trace to create a digital data set of differences; a third stage comprising a programmed analyzer configured to compare the n-filtered digital data sets from the first stage with the digital data set of differences from the second stage to create a digital data set of approximate values; and a fourth stage comprising a programmed calculator and data analyzer configured to add the digital data set of approximate values generated by the third stage to the n-filtered digital data sets from the first stage.
