Speaker: The chief physician of Cardiovascular Center of Xiyuan Hospital, Shi Dazhuo Academy of Chinese Medicine slapped the inside of elbow hard after a sudden myocardial infarction? Is the first aid method reliable? Not reliable. It can even be said that this is a misleading practice! If the patient has acute myocardial infarction, use? Tap the inside of the elbow? This method will not dredge blood vessels, but will miss the best treatment time, delay the rescue opportunity, adversely affect the prognosis of patients, and even lead to death. We must remember that time is life in acute myocardial infarction. How to give correct first aid to sudden myocardial infarction? When the patient has acute chest pain, squeezing feeling, dying feeling, sweating, blood pressure drop, etc. He should use first-aid drugs such as nitroglycerin or take other first-aid Chinese medicines under his tongue. If it doesn't relieve after 3-5 minutes, you can use it again. If it is still not relieved, you should call the emergency number and send it to the hospital for professional treatment.
