The basis of determination of distorted parts of the SD by the deflection voltage
are the principles of compliance with the required voltage levels on the ES buses and in control nodes of the PSS voltage as well as load of the individual elements of EN and EE consumers not exceeding permissible or maximum permissible values for them.
The range of net QRS amplitudes (net amplitude = positive minus negative deflection voltages
of QRS complex) and QRS durations were -6.6 to 5.8 mV and 0.03-0.17 seconds in all leads.
Values for the net QRS amplitude, which demonstrates the positive minus negative deflection voltages
of the QRS complexes are included in Table 2.
