第七节心脏损伤（Seventh heart injuries） Heart injury (cardiac injury) can be divided into blunt heart injury and penetrating heart injury. Blunt injuries are mostly caused by the chest The heart is subjected to blunt violence during the isometric systole, such as impingement, deceleration, extrusion, falling down, and shock The worst consequences. Penetrating injuries are mostly caused by sharp instruments, blades or firearms. (1) blunt heart injury (blunt cardiac iniurv) is associated with blunt trauma and blunt violence The second debate in Naoko Shou Jue to arsenic The impact velocity, quality, duration, cardiac and cardiac stress area shrink. The light group is asymptomatic myocardial contusion Injuries can cause heart rupture even in people with severe injuries. The vast majority of patients with blunt heart rupture died at the scene of the accident, and very few were possible Successfully delivered to the hospital through effective field first aid. Clinically, myocardial contusion is the most common, but light causes epicardial myocardium only To the endocardial bleeding, a small amount of myocardial fiber rupture; severe myocardial contusion may occur, large myocardial hemorrhage is bad Death and even intracardiac structures such as valves, leg cords, and ventricular septal injuries. The repair after myocardial contusion may leave paralysis mark, very much To the day after the occurrence of ventricular aneurysm. The main causes of severe myocardial contusion are severe arrhythmia or heart failure. The clinical manifestation and diagnosis of mild myocardial contusion may have no obvious symptoms. The middle and severe contusion may show chest pain and heart I, angina symptoms such as shortness of breath, even. Patients may suffer from soft tissue injuries and sternal fractures of the chest wall. Myocardial contusion The diagnosis of (myocardial, contusion) relies mainly on clinician vigilance and assisted examination. Common auxiliary examinations For the electrocardi
