Abstract: The stimulation frequency of a heart pacemaker is controlled dependent on a signal representative of the blood oxygen content of the patient. The blood oxygen dependent signal is generated by a blood oxygen sensor. A temperature sensor generates a separate signal dependent on blood temperature. The blood oxygen and blood temperature signals are combined such that the blood oxygen signal is lowered, i.e., the value thereof is reduced, in ranges of higher physical load indicated by an increase in the temperature dependent signal. The combined signal is used to control the stimulation frequency of a heart pacemaker so that the stimulation frequency is increased, if blood oxygen saturation is decreasing and/or blood temperature is increasing.

Abstract: To determine the heat or cold sensation or pain threshold of a human being, thermode is applied to the skin of the subject under investigation, and the temperature is varied until the subject feels pain.
