System and method for modulating the pacing rate based on patient activity and position
First Claim
Patent Images
1. In an implantable cardiac stimulation device, a method of determining a pacing rate, the method comprising:
- monitoring an indicator of patient activity and generating corresponding signals;
processing the signals to determine a patient'"'"'s activity level;
monitoring the patient'"'"'s activity level for a predetermined change in the activity level; and
pacing at an orthostatic compensation pacing rate if the predetermined change in the activity level is sensed.

Abstract
A system and method are provided for compensating for the drop in blood pressure upon standing. Upon transition from prolonged sitting, lying down, or standing position, the pacemaker abruptly increasing its pacing rate upon postural transition. This pacing rate is triggered when a patient stands after a prolonged reclined or supine/prone position.
