Rate Adaptation
Cylos uses two completely separate principles for rate adaptation:
• Rate adaptation by an accelerometer
• Physiologic rate adaptation using Closed Loop Stimulation
The programmable rate-adaptive modes fall into the following
categories:
Rate Adaptation
Closed Loop
Stimulation
Accelerometer-based
physiological
rate adaptation
activity modes
atrial overdrive
pacing

Table 7: Overview of rate adaptation
Accelerometer-Based Rate Adaptation
Sensor-controlled rate adaptation allows an adjustment of the pacing
rate to changing metabolic needs at rest and during exertion. The
pacing rate increases at the onset of exercise to the sensor-determined
rate. It slowly returns to the basic rate when exercise is no longer
detected.
