With a positive difference in the ratio of KI, KI. Kz signs At | and Atj does not change. With a negative difference in the relationship, the signs of Ati and Atj change to the opposite, if they have not changed in the current cycle. The time ti is determined, for example, by the ECG R-wave, and the time ti - by the RR interval, averaged over 1b cycles. n t.
