Abstract: A system and method for pacing rate control in a cardiac rhythm management (CRM) system. The method includes acquiring a pressure signal representative of coronary venous pressure (CVP) from a pressure sensor implanted within a coronary vein of the patient and generating a CVP waveform from the pressure signal. A pacing stimulus is applied to the patient's heart, and the pacing rate is increased in response to increases in patient's metabolic demand. The CVP index is monitored during the pacing rate increase, and the CRM system detects a reduction in the patient's hemodymanic performance based on the CVP index and establishes a maximum rate setting based on the pacing rate corresponding to the reduction in the patient's hemodynamic performance.
Abstract translation: 用于心律管理（CRM）系统中起搏速率控制的系统和方法。 该方法包括从植入患者冠状静脉内的压力传感器获取代表冠状静脉压（CVP）的压力信号，并从压力信号产生CVP波形。 对患者的心脏施加起搏刺激，并且响应于患者代谢需求的增加而起搏速率增加。 在起搏速率增加期间监测CVP指数，并且CRM系统基于CVP指数检测患者血液动力学性能的降低，并且基于与患者血液动力学性能的降低相对应的起搏速率来建立最大速率设定。
