Panic and shortness of breath and weakness of limbs are symptoms that everyone has had, and many patients feel anxious and worried. Occasional panic and shortness of breath and weakness may be due to lack of sleep, smoking, drinking too much tea and coffee, poor rest, etc., without treatment as long as more rest can be relieved; if it lasts for a long time, accompanied by breathing difficulties and other symptoms, you need to consider that it may be caused by organic heart disease, let’s take a look at it below. 1, panic and shortness of breath may also be one of the symptoms of coronary heart disease. Coronary heart disease is an organic heart disease, mainly ischemic heart disease caused by atherosclerosis of coronary arteries. Patients with coronary heart disease face the threat of myocardial ischemic necrosis at any time, the lighter the symptoms of panic and shortness of breath, weakness, the heavier the angina pectoris, myocardial infarction and even sudden death. 2, myocardial ischemia is one of the important causes of patients’ panic and shortness of breath and general weakness. The function of the heart is greatly affected, the beat is weak, feeling panic, the blood transfusion for the whole body is greatly reduced, and the limbs are weak. The coronary artery is the main artery for blood transfusion to the heart, and the narrowing or spasm of the coronary artery can easily cause myocardial ischemia. 3, patients with viral myocarditis will also have symptoms of panic and shortness of breath and general weakness. This is mostly related to ventricular hypertrophy and impaired cardiac function due to myocarditis. Especially in patients with cardiac insufficiency, the symptoms are especially obvious. In this case, it can be relieved by activating blood circulation, strengthening myocardial nutrition and controlling blood pressure. When episodic symptoms of shortness of breath occur, it is possible that the symptoms are just bad sleep or related to smoking and tea, and generally disappear after supplemental rest. In normal life, we should keep our mood relaxed, happy and optimistic, strengthen physical exercise, and be calm to help our health. Of course, if the panic, shortness of breath lasts for a long time, and accompanied by rapid heartbeat, dizziness, limb weakness, it is necessary to go to the hospital in time to do the relevant examination, do not delay, early prevention before it is done.
