Physiologic rate response

Twin trace is designed to physiologically modulate the heart rhythm by combining Accelerometer and Minute Ventilation sensors.

Combined sensors for physiologic response to suit patient activity.

  1. Accelerometer sensor: Fast response at the beginning and end of exercise.
  2. Minute Ventilation sensor: Physiologically-based sensor detects increased metabolic need and adapts pacing rate in proportion to exercise.
  3. Sensor cross-checking: The two sensors continually cross-check each other, preventing unnecessary rate increases due to artifacts.

 

 

How does it work

  1. The Accelerometer sensor is the first to detect an activity phase: Twin trace immediately adapts pacing rate to this “acceleration” information.
  2. As the Minute Ventilation sensor detects the activity phase: Twin trace then adapts the pacing rate to the “minute ventilation” information.
  3. The Accelerometer sensor is the first to detect the end of activity: Twin trace then initiates the recovery phase to the basic rate.
