This analysis can be applied to heat engines and pumps, including the heart. A considerable amount of information on cardiac performance can be determined from the ''pressure vs. volume'' plot (pressure-volume diagram). A number of methods have been determined for measuring PV-loop values experimentally. == Cardiac pressure-volume loops== Real-time left ventricular (LV) pressure-volume loops provide a framework for understanding cardiac mechanics in experimental animals and humans. Such loops can be generated by real-time measurement of pressure and volume within the left ventricle. Several physiologically relevant hemodynamic parameters such as stroke volume, cardiac output, ejection fraction, myocardial contractility, etc. can be determined from these loops. To generate a PV loop for the left ventricle, the LV pressure is plotted against LV volume at multiple time points during a single cardiac cycle. 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「Pressure-volume loop analysis in cardiology」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.
