Rapid heartbeat, panic, chest tightness, and chest discomfort may be early reactions to hypoglycemia caused by prolonged absence of food. In addition, these symptoms are commonly seen in clinical heart diseases, such as cardiac insufficiency and heart failure, and may also be caused by lung diseases, such as pleural effusion, hyperthyroidism, anemia or psychosomatic diseases. If a fast heartbeat, panic, chest tightness and chest discomfort occur in menopausal women, the possibility of menopausal syndrome cannot be ruled out.1. Heart disease: When rapid arrhythmia occurs or when suffering from cardiac insufficiency or even heart failure, it can cause symptoms such as fast heartbeat, panic and chest tightness. In this case, you need to consult a doctor as soon as possible, improve the electrocardiogram and other related examinations to clarify the cause and then treat the cause and symptoms. 2. Lung diseases: If you suffer from lung diseases, such as infection or tumor causing pleural effusion, you will also experience chest discomfort such as fast heartbeat, chest tightness and panic. If the chest discomfort is caused by pleural effusion, often accompanied by pleural friction sounds, the diagnosis can be clarified by chest X-ray and other examinations; 3. Other diseases: clinical symptoms such as fast heartbeat, panic and chest tightness may also be caused by hyperthyroidism and anemia, which need to be judged and treated according to whether the patient has other accompanying symptoms or signs, combined with laboratory tests. In addition, if the patient still feels uncomfortable after excluding cardiopulmonary and other diseases, it should be considered whether it is caused by mental stress, or even whether it is a psychosomatic disease, such as anxiety disorder or depression. If the patient is a woman around 50 years old and no organic disease is found after examination, it may be caused by menopause syndrome and can be relieved by taking prozac and glutamate.
