If a patient develops sudden heart pumping pain, for patients with a previous history of coronary artery disease, it is highly suspected to cardiogenic diseases, such as unstable angina, malignant arrhythmia, all of which have pain caused by sudden coronary artery supply deficiency to the heart. In addition, for myocarditis, pericarditis, valvular heart disease, hypertrophic obstructive cardiomyopathy, and rheumatic heart disease, patients can also suffer from sudden ischemia, spasm, and stenosis of the coronary arteries, causing twitching-like pain. If the patient has previous endocrine metabolic disorders, it is easy to lead to plant nerve dysfunction, and sudden precordial twitching pain can also occur when cardiac neurosis occurs. For diseases of the digestive system, such as reflux esophagitis and gastroduodenal ulcer pain, there may also be sudden precordial throbbing pain as described above. Finally, for respiratory system diseases, such as pneumothorax and massive lung infection, the above symptoms may also occur.
