Then pick the appropriate analysis techniques to answer those questions. If you can share those questions on this thread maybe we can be of more assistance.</P><P>&nbsp;</P> Fri, 13 Dec 2024 17:26:45 GMT https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822656#M100236 P_Bartell 2024-12-13T17:26:45Z https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822673#M100238 <P>First, welcome to the community. &nbsp;Echoing what Pete suggested, what questions do you have about heart rate? &nbsp;For example do you want to compare heart rates for individuals at different ages or sexes or with different underlying conditions? &nbsp;Do you want to determine if heart rate is stable for a particular individual? &nbsp;Do you want to understand what factors mat contribute to the variation in heart rate? Do you want to assess the measurement system? &nbsp;etc.</P> Fri, 13 Dec 2024 18:22:04 GMT https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822673#M100238 statman 2024-12-13T18:22:04Z https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822765#M100257 <P>私は現在エコーで脳血流や腸管血流を測定し、様々な臨床所見との関連を調べています。自律神経がこれらの血流に関連しているのではないかと指摘を受け、自律神経の評価を考えています。</P><P>血流測定時の10分間、心電図のデータを記録しています。そのデータからRR間隔の差分を計算しました。</P><P>今後はフーリエ変換でパワースペクトル密度の計算をしたいのですが、どのように行えば良いのか分かりません。</P><P>教えていただければありがたいです。</P> Sat, 14 Dec 2024 12:09:19 GMT https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822765#M100257 CoverPuppy232 2024-12-14T12:09:19Z https://community.jmp.com/t5/Discussions/JMP%E3%81%A7%E5%BF%83%E6%8B%8D%E5%A4%89%E5%8B%95%E3%81%AE%E8%A7%A3%E6%9E%90%E3%82%92%E8%A1%8C%E3%81%86%E6%96%B9%E6%B3%95%E3%81%AB%E3%81%A4%E3%81%84%E3%81%A6/m-p/822767#M100259 <P>Thanks for the additional information.
