Title
(JA) 信号通過時間を用いた心血管症状の監視
Abstract
(JA)

心血管症状、すなわち、高拍出性循環、血管拡張、血管収縮、または中枢から末梢の動脈圧分断状態を監視する方法が記載される。これらの方法は、被験者の心臓活動と比例する、または被験者の心臓活動の関数である中枢信号、および中枢信号に関連する信号と比例する、または中枢信号に関連する信号の関数である末梢信号を測定することを伴う。次いで、同一の心臓事象を表す中枢および末梢信号における特徴の間の時間差を算出する。心血管症状は、時間差が閾値よりも大きい場合もしくは小さい場合、特定された期間にわたって時間差が閾値よりも大きい場合もしくは小さい場合、または特定された期間にわたって時間の有意な統計的変化がある場合に示される。これらの方法は、被験者が心血管症状を体験していることをユーザに警告することができ、それは臨床医が被検者に治療を適切に提供することを可能にすることができる。
