If symptoms such as chest tightness, panic, palpitations (rapid heartbeat, often accompanied by panic), anxiety, and high blood pressure are present, diseases that can be considered include hypertension, arrhythmia, hypoglycemia, and anxiety. 1. Hypertension: Hypertensive patients with poorly controlled blood pressure may experience symptoms in the affected organs in addition to blood pressure exceeding normal values. When the heart is involved, symptoms of chest tightness, palpitations and shortness of breath will occur; when the brain is involved, symptoms of dizziness, headache and anxiety will occur. In more serious cases, there will be blurred vision and nosebleed. 2. Arrhythmia: Hypertension patients are prone to arrhythmia, high blood pressure, chest tightness, palpitations, dizziness and other manifestations. At this time, increased blood pressure can easily lead to blood stagnation, which in turn leads to lumen narrowing and coronary artery atherosclerosis, thrombosis is easy to form, coupled with insufficient blood supply to the heart muscle for a long period of time, the likelihood of the occurrence of atrial fibrillation increased. 3. Hypoglycemia: when the blood sugar level is low, due to sympathetic nerve excitation, it will cause the secretion of adrenocorticotropic hormone, epinephrine, norepinephrine, at this time, it can make the blood pressure appear to be elevated. At the same time can affect the heart energy supply, chest tightness, panic, palpitations and even anxiety performance. 4. Anxiety disorders: Anxiety disorders can be caused by long-term stress, mental tension and other factors, the body localized functional discomfort, such as panic, chest tightness, dizziness, fatigue and other symptoms. At the same time, the anxiety patient’s spirit is in a state of tension, when the sympathetic nerve excitation can cause the blood pressure to increase. If the above symptoms are not relieved, or accompanied by other symptoms, you should go to the hospital in a timely manner, with the help of the doctor to identify the cause and give targeted treatment.
