Heart pacemaker has regulator for load-dependent control of atrial stimulation frequency, derives stimulation frequency from physiological load on wearer for output to stimulation unit

摘要

The adaptive rate pacemaker has a stimulation unit (110) with an arrangement for stimulating the ventricle and/or atrium, a sensor unit for detecting the electrical activity of the ventricle and/or atrium, especially for measuring the time interval between an atrial event and a subsequent ventricle event and a computation unit for deriving the stimulation frequency from the physiological load on the wearer and outputting it to the stimulation unit. The computation unit has a regulating unit (103) that computes the frequency value with a recursive differential equation (104) using a value (4) measured by the sensor unit (100) as input parameter and a specific reference value for the heart pacemaker as control parameter.
