Hemodynamic sensors.
Present adaptive-rate pacemakers use a range of sensors for implementation in open-loop and closed-loop control systems. Hemodynamic sensors that detect the mechanical action of the heart and blood flow offer additional features to implement physiologic rate adaption in rate-controlling systems and rate-limiting systems. Examples of 2 such sensors are presented.
