При положительной разности отно-шений KI, KI. Кз знаки At| и Atj не мен етс . При отрицательной разности отношений знаки Ati и Atj мен йтс на противоположные , если они не мен лись в текущем цикле. Врем ti определ ют, напрнмер по R-зубцу ЭКГ, а врем ti - по RR-интервалу, осредненТюму за 1б циклов Йзмер ар Т рйальное Швление , выдел ют PC, Pg, Pa, KI , Kj, Кз и провод т автоматическую коррекцию t н t.In these cycles, the phase of correction is determined (siak At): the sign of the difference between K is determined by the sign of Ati, the sign of the difference between Kj is determined by Atj, and the sign of the difference between Ke is simultaneously the sign of Ati and Atj. 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.
