Low blood pressure, high heart rate and shortness of breath are generally related to increased sympathetic excitability, and can be improved by general treatment and medication. 1. General treatment: eat a light diet, avoid spicy and stimulating foods with high salt content. Adjust the lifestyle, regular work and rest, regular blood pressure and heart rate monitoring, avoid mental stimulation and overwork. 2. Medication: Take medication such as metoprolol, bisoprolol and bethanechol under doctor’s guidance, as well as angiotensin receptor antagonist drugs, such as enalapril tablets, which can reduce sympathetic excitability, help reduce diastolic blood pressure and heart rate, and improve related symptoms. If patients experience uncomfortable symptoms, they should consult a doctor in time. When using medication, they must follow the doctor’s instructions, apply the medication reasonably, and do not use the medication arbitrarily to avoid causing serious adverse reactions.
