A blood pressure value of 103/63 mmHg is within the normal range, and a healthy adult’s blood pressure should fluctuate between 90-140 mmHg systolic and 60-90 mmHg diastolic. If the blood pressure is 103/63 mmHg and there are no symptoms of hypotension, such as peripheral weakness, dizziness, palpitations, blackness in front of the eyes, or blurred vision, then the condition is completely normal. In middle-aged and elderly patients with ischemic cerebrovascular disease, because of the presence of definite intracranial stenosis and stenosis due to atherosclerotic plaque in the carotid artery, this blood pressure value may lead to the exacerbation of symptoms of ischemic cerebrovascular disease and the development of transient hemiplegia, blurred vision, and aphasia, so patients should not control their blood pressure too low.
