Upon auscultation, this sign is an extra heart sound of to-and-fro character, typically with three components, one systolic and two diastolic. It resembles the sound of squeaky leather and often is described as grating, scratching, or rasping. The sound seems very close to the ear and may seem louder than or may even mask the other heart sounds. The sound usually is best heard between the apex and sternum but may be widespread. ==Cause== The pericardium is a double-walled sac around the heart. The inner and outer (visceral and parietal, respectively) layers are normally lubricated by a small amount of pericardial fluid, but the inflammation of pericardium causes the walls to rub against each other with audible friction. In children, rheumatic fever is often the cause of pericardial friction rub. 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「Pericardial friction rub」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.
