''Journal of Critical Care'', Volume 14, Issue 4, Pages 177–185〕 It can be used as an indicator of diastolic dysfunction. It can be measured by simultaneous Doppler echocardiography and M-mode sonography, or better still, by simultaneous phonocardiogram and transmitral Doppler.〔(anaesthetist.com >Diastolic dysfunction ) Lara Hopley and Jo van Schalkwyk. Date of last update: 2009-06-05〕 Prolonged IVRT indicates poor myocardial relaxation. A normal IVRT is about 70 ± 12 ms, and approximately 10 ms longer in people over forty years.〔 In abnormal relaxation, IVRT is usually in excess of 110 ms.〔 With restrictive ventricular filling, it is usually under 60 ms.〔 ==See also== *Isovolumetric contraction 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Isovolumic relaxation time」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
