The world's smallest CRT pacemaker.1 Synchrony in a small size

Reply CRT-P is designed to improve patient comfort with with no compromise on longevity.



Sleep Apnea Monitoring measures respiration pauses and reduction in respiration.


Dual Sensor

Designed to physiologically modulate heart rhythm by combining accelerometer and minute ventilation sensors.

The smallest CRT-P in the world at 11.3 cc1

Designed to improve implant experience and patient comfort:

  • Physiologic shape with gentle curves
  • Allows for a smaller incision and reduced pocket size
  • Better fit for replacements and upgrades

Built on proven technology

Reply CRT-P is built on the heritage of Sorin pacemaker technology, proven in practice5–7 and is powered by intelligent algorithms6, 7 with no compromise on longevity.8

Sleep Apnea Monitoring

  • Early detection, lifetime monitoring.
  • SAM allows you to screen patients for severe sleep apnea as well as monitor the evolution of the disease.

Dual Sensor

  • Need for accurate Rate Response in CRT.
  • Exercise is proven to have positive effects on mortality, morbidity and quality of life for CRT patients.2–4
