DEFINITION

Classification: 607/17

Parameter control in response to sensed physiological load on heart:

Subject matter under 9 for controlling the pacing parameter, usually pulse rate, by sensing changes in the physiological load on the heart as evidenced by changes in a body condition, due to the changes in the person's activity, state of health.

(1) Note. Conditions such as blood pressure, body temperature, and blood chemistry are detected conditions monitored.
