强血压变化检测
摘要：
本发明涉及在血液透析期间病人的基于心脏行为的血压快速降低的预测。所述的报警装置(100)包括输入接口(110)、第一和第二分析单元(130；140)、和报警产生单元(150)，病人的心电图信号(HECG)通过该输入接口(110)被第一分析单元(130)接收，其响应于此产生一个心率变化信号(PHRV)。第二分析单元(140)根据该心电图信号(HECG)确定异常心跳的强度(pEBC)。报警产生单元(150)确定该异常心跳的强度(pEBC)是否相对较低或较高。在相对较低的情况下，如果该心率变化信号(PHRV)满足第一报警标准，该报警产生单元(150)触发一个报警信号(α)，以指示估计的快速血压降低。在强度相对较高的情况下，如果该异常心跳的强度(pEBC)满足第二报警标准，则该报警产生单元触发该报警信号(α)。
摘要（英）：

The invention relates to cardiac-activity based prediction of a rapid drop in a patient's blood pressure during hemodialysis. A proposed alarm apparatus (100) includes an input interface (110), primary and secondary analysis units (130; 140) and an alarm-generating unit (150). An electrocardiogram signal (HECG) of the patient is received via the input interface (110) by the primary analysis unit (130), which in response thereto produces a heart-rate-variability signal (PHRV)- The secondary analysis unit (140) determines an intensity of ectopic beats (PEBC) based on the electrocardiogram signal (HECG)- The alarm-generating unit (150) investigates whether the intensity of ectopic beats (PEBC) is relatively low or relatively high. In case of a relatively low intensity, the unit (150) triggers an alarm signal (alpha) indicative of an estimated rapid blood pressure decrease if the heart-rate-variability signal (PHRV) fulfills a first alarm criterion. In case of a relatively high intensity, however, the unit (150) triggers the alarm signal (alpha) if the intensity of the ectopic beats (PEBC) fulfils a second alarm criterion.
