The present invention consists of a modification and a new method of todays art 12 lead resting electrocardiogram The modifications include: Elimination of connecting means to record todays art Leads connecting means to connect a common positive electrode, placed on the left leg, to all the positive terminals of the electrocardiographic amplifiers connecting means to connect the negative electrodes, placed on the chest to the negative terminals of each individual electrocardiographic amplifier reporting the results of the electrocardiogram including all the digital data sets obtained and calculated by the electrocardiograph in a disk, and a remote safe Data Bank for easy retrieval. A method of reprograming the electrocardiograph calculator to calculate the second derivative of the maximal and minimal values of each structure of the myocardium at specific instants of the electrocardiographic trace calculate the value generated by the left leg and the values generated by each negative electrode.
