Recently, 120 Beijing Emergency Center received a middle-aged male patient  with chest tightness and chest pain. He has taken oral nitroglycerin but the  pain was not relieved. Based on years of clinical experience, it was diagnosed  as myocardial infarction. The emergency doctor immediately told the patient that  it is strictly forbidden to go to the hospital by himself. He should sit or lie  down and wait for the ambulance. The preliminary examination showed that the  patient had an acute inferior myocardial infarction. The doctor immediately gave  emergency measures and contacted the 120 dispatching command center to establish  a green channel to send the patient to a nearby hospital for further  treatment.

　　Doctors always tell patients with acute myocardial infarction not to move.  It is because when a myocardial infarction occurs, the heart and blood vessels  are blocked and the myocardium is dying. Any behavior that aggravates the  heartbeat will increase the speed of myocardial necrosis. Pain or bleeding will  be worsens when you move. The heart is more fragile than the arms and legs.  Moving will increase the burden on the heart, which may cause heart rupture and  sudden arrest at any time. The second reason is that when myocardial infarction  will stop the blood supply and cause abnormal electrical activity of the heart,  and malignant arrhythmias such as ventricular fibrillation may occur at any  time. If the chest pain persists and does not relieve, it is necessary to call  120 as soon as possible and the patient should lie down and wait. This is also  the reason why patients are not allowed to move when there is an acute  myocardial infarction.
