Title
(ZH) 使用信号渡越时间来监控心血管状况
Abstract
(ZH)

本发明描述了一种用于监控心血管状况的方法,该心血管状况即高动力性循环、血管舒张、血管收缩或中心到外周的动脉压去耦情况。这些方法涉及测量与对象心脏活动成比例的或作为对象心脏活动的函数的中心信号,以及与该中心信号成比例的或作为与该中心信号相关的信号的函数的外周信号。然后计算表示相同心脏事件的中心和外周信号中的特征之间的时间差。若时间差高于或低于阈值,或者若在特定时间段内时间差高于或低于阈值,或者在特定时间段内的时间存在重大统计学变化,则指明了心血管状况。这些方法可以警告用户对象正在经受心血管状况,其使临床医生能够适当地为对象提供治疗。
