A high pressure of 120 mmHg and a low pressure of 58 mmHg are generally abnormal. High pressure is also known as systolic pressure and low pressure is also known as diastolic pressure. Normal blood pressure is between 90 and 139 mm Hg systolic, and diastolic blood pressure is between 60 and 89 mm Hg. A patient with a diastolic blood pressure of 58 mm Hg has a low blood pressure. Blood pressure that is occasionally 120 mm Hg systolic and 58 mm Hg diastolic is generally of less consequence. If it is the norm, it is low pressure and is generally a symptom of hypotension. Patients with low blood pressure should pay attention to a reasonable diet and a healthy lifestyle. Medications such as ephedrine hydrochloride tablets, midodrine hydrochloride tablets, or shengqin drink can be used for treatment under the guidance of a doctor to alleviate the condition. If any discomfort occurs, consult a doctor in time and use the medication under the guidance of a professional doctor.
