Acute myocardial infarction, which may be signs

Patients with acute myocardial infarction according to the severity of their different physical examination can be completely normal, but signs can be found as follows: (1) General: Patients with acute myocardial infarction in more anxiety and suffering state, want exogenous shock to supine and looking pale, your lips cyanosis, cold sweat, heart failure who were semi - supine. (2) heart rate and blood pressure: additional fast heart rate, the minority can also slow down. 1 / 3 to 1 / 2 the patient early onset of sinus tachycardia, mainly with pain, anxiety, heart failure and other relevant. In addition to blood pressure may increase the incidence of early, almost all patients have lower blood pressure. The past hypertension patients, a considerable number of patients unused part of antihypertensive drugs blood pressure fell to normal, but 2 / 3 of patients in the infarct after 3 to 6 months of blood pressure increased again. Generally speaking, more than half of inferior myocardial infarction due to vagal excitatory higher performance associated with hypotension and / or bradycardia, and approximately one half of the anterior wall myocardial infarction patients due to over-excitement can be sympathetic with mild hypertension and / or tachycardia. (3) cardiac signs: ① more than half of heart patients with mild to moderate voiced sector expansion. ② apical first heart sound (S - 1) reduced, there will be the fourth heart sounds or S-3 Law (Room of law). ③ there will be varying degrees of heart murmur and pericardial friction sound. ④ can have all kinds of arrhythmia. (4) the chest examination can be heard the sound Luo moist lung, a serious left ventricular failure can be heard Wheezing and diffuse the sound. When we can see right ventricular infarct jugular and accompanied by abnormal pulse.
