Implantable sensors play an important role in physiological cardiac pacing. Sensors can be classified according to the technical methods in which sensing is achieved: the sensing of the evoked ventricular response, intrathoracic impedance and body acceleration forces, and the incorporation of special sensors on pacing electrodes. These sensors differ in their relative merits in terms of speed, proportionality, sensitivity, and specificity of rate response. The efficacy of a sensor can be significantly modified by the algorithm used in relating sensor signal to a pacing rate change. The currently available types of sensors and algorithms are summarized and compared in this review article. The relative merits of these sensors and algorithms form the basis for designing a multisensor pacing system.
植入式传感器在生理性心脏起搏中发挥着重要作用。传感器可根据实现传感的技术方法进行分类:诱发心室反应的传感、胸内阻抗和身体加速力的传感,以及在起搏电极上集成特殊传感器。这些传感器在速率反应的速度、比例性、敏感性和特异性方面各有优劣。传感器的效能会因将传感器信号与起搏速率变化相关联所使用的算法而显著改变。本文综述总结并比较了当前可用的传感器类型和算法。这些传感器和算法的相对优点构成了设计多传感器起搏系统的基础。
