Electrocardiographic method and apparatus based on bipolar, non-vectorial, truncal leads or real unipolar leads

A modified electrocardiograph configured to record electrical activity of specific myocardial structures of a patient, the electrocardiograph comprising:

• a Constant Value Reference Electrode 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;
• an amplifier F, wherein a positive terminal of amplifier F is electrically connected to said Constant Value Reference Electrode;
• and a negative terminal of amplifier F is connected to a negative Exploring Electrode that is adapted to be placed on an extremity of a 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 and an A/D converter F connected to amplifier F, wherein said plurality of A/D convertors and A/D converter F are connected to a microprocessor of the modified electrocardiograph, said microprocessor comprising:
• a first stage configured to receive and filter signals from each of said Exploring Negative Electrodes adapted to be placed on a torso of the patient and said Constant Value Reference Electrode obtained with the plurality of amplifiers (1, 2, to n), n=15-100 to create n-filtered digital data sets and is further configured to receive and filter signals from the Exploring Negative Electrode adapted to be placed on an extremity of the patient and said Constant Value Reference Electrode obtained with amplifier F to create an F filtered digital data set;
• a second stage comprising a programmed analyzer configured to subtract the F digital data set from the n-filtered digital data sets to create a digital data set of bipolar values;
• to select and pair minimum and maximal values of the digital data set of bipolar values 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 digital data set of bipolar values from the second 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 digital data set of bipolar values from the second stage.
