目前已知有20多种病在心尖区可听到舒张期隆隆样杂音,所以并不是风湿性二尖瓣狭窄一病所仅有。由于病因、病理不同,各病的杂音特点也不尽相同。本文仅将这些疾病所产生舒张期杂音的机理、特点作一简要介绍: 一、风湿性二尖瓣狭窄:杂音是由于左心室舒张时,血液从左心房通过狭窄的左室流入道,流至较宽大的左心室发生旋涡所致。杂音特点:呈雷鸣样,于舒张中、末期加强——递增型,常伴有第一心音亢进及猫喘。如同时闻及开瓣音则可肯定是风湿性二尖瓣狭窄。杂音的 It is known that there are more than 20 kinds of diseases in the apex area can be heard diastolic rumbling noise, so not the only rheumatic mitral stenosis. Due to the etiology, pathology, the characteristics of the murmur of each disease are not the same. This article only the diastolic murmur caused by these diseases, the characteristics of a brief introduction: First, rheumatic mitral stenosis: noise is due to left ventricular diastolic, the blood flow from the left atrium through the narrow left ventricular flow, to Larger ventricular vortex caused. Moxibustion features: a thunder-like, in the diastolic, the end to strengthen - increasing type, often accompanied by first heart sound hyperthyroidism and cat asthma. As the same smell and open flap sound can certainly be rheumatic mitral stenosis. Noise
