| 1. | Mitral valve prolapse
二尖瓣脱垂 |
| 2. | Some persons with atypical chest pain have physical signs or echocardiographic evidence of mitral valve prolapse
一些非典型胸痛患者可有二尖瓣脱垂的体征或超声心动图证据。 |
| 3. | Likewise , the stethoscope allows the examiner to detect mid systolic clicks in mitral valve prolapse and pericardial friction rubs
同样听诊器有利于检查者发现二尖瓣脱垂时收缩中期喀喇音和心包摩擦音。 |
| 4. | Whether the pain is related to the mitral valve prolapse or whether it is an epiphenomenon is controversial because it is common in the absence of evident prolapse
不过，疼痛是否与二尖瓣脱垂相关，抑或只是一种偶发现象，对此人们尚有争议，因为这种疼痛即便是在无明显脱垂时也很常见。 |
| 5. | Late systolic murmurs begin in midsystole and extend to or through s2 . they may be heard in mitral valve prolapse ( frequently accompanied by midsystolic clicks ) or coarctation of the aorta
收缩期晚期杂音始于收缩期中期，延至或贯穿s2 。可在二尖瓣脱垂（通常伴有收缩中期喀喇音）或主动脉瓣缩缝时听到。 |
| 6. | A thorough family history should be taken because many cardiac disorders ( eg , coronary artery disease [ cad ] , systemic hypertension , bicuspid aortic valve , hypertrophic cardiomyopathy , mitral valve prolapse ) have a heritable basis
很多心脏疾病(如冠状动脉疾病( cad ) 、全身性高血压、二叶主动脉瓣疾病、肥厚型心肌病、二尖瓣脱垂)都有遗传基础，因此应收集详尽的家族病史。 |
