缩窄性心包炎时常见心包叩击音(pericardialknock),有假设认为:缩窄性心包炎时,不能膨胀的,增厚、纤维化或钙化的心包使心室扩张到一定限度,当达到这个限度时,舒张期心室充盈突然减慢,心包叩击音与此有关.为证实这种假设,作者对7例经血液动力学和病理学证实的缩窄性心包炎患者和7名正常人进行了左室造影、心音图和颈外静脉搏动图的观察.7名正常人在舒张期的初始10%中,舒张期充盈呈现快速斜率,而在其余的90%舒张期内是较缓慢 Common constrictive pericarditis pericardial noise (pericardialknock), there is the assumption that: constrictive pericarditis, not expansion, thickened, fibrotic or calcified pericardium to expand the ventricle to a certain limit, when this limit is reached , The diastolic ventricular filling suddenly slowed down and the pericardial percussion tone was associated with this.To validate this hypothesis, the authors performed a series of seven patients with constrictive pericarditis confirmed by hemodynamics and pathology and seven normal individuals Left ventricular angiography, phonocardiogram and jugular venous pulsation.7,7 normal subjects showed a fast slope in diastolic filling in the first 10% of diastolic and a slower rate in the remaining 90% diastolic
