Abstract
A patient with acute myocardial infarction developed a loud systolic sound and apical thrill. Doppler ultrasound excluded interventricular septal rupture and significant mitral or tricuspid regurgitation. Auscultatory abnormalities disappeared after removal of a temporary pacing electrode, suggesting that the friction it created with intracardiac structures was responsible for these findings.
摘要
一名急性心肌梗死患者出现响亮的收缩期声音和心尖部震颤。多普勒超声排除了室间隔破裂以及明显的二尖瓣或三尖瓣反流。在移除临时起搏电极后，听诊异常消失，提示其与心内结构产生的摩擦是导致这些表现的原因。
