REGELSCHALTUNG ZUR ANPASSUNG DER STIMULATIONSFREQUENZ EINES HERZSCHRITTMACHERS AN DIE BELASTUNG EINES PATIENTEN.

摘要

The control circuit produces a control variable equal to the ratio of the difference between a present measurement and a further measurement divided by the max. change in the measurement.. This variable is used to control the frequency so that the frequency change is such that the direction of the change depends on the sign of the control variable and the magntiude of the control variable. The difference is the difference between the present measurement and the min. value of that parameter or its max. The frequency is set directly as a function of the control variable.
