Normal diastolic blood pressure is between 60 mmHg and 90 mmHg. If it is lower than 60 mmHg, it can be called reduced diastolic blood pressure, also called low blood pressure. Low diastolic blood pressure can be caused by a variety of conditions in the elderly, including taking antihypertensive drugs, atherosclerosis, cardiac arrhythmia, and shock.
1. Due to atherosclerosis in elderly patients, the elastic reservoir function of large arteries decreases, resulting in increased systolic blood pressure, decreased diastolic blood pressure, and increased pulse pressure difference.
2. Due to excessive use of antihypertensive drugs, resulting in lower systolic and diastolic blood pressure.
3. Tachyarrhythmias, including rapid atrial fibrillation, atrial flutter, supraventricular tachycardia, ventricular tachycardia, and so on, can also cause a drop in blood pressure.
4. Postural hypotension, after changing body position, both systolic and diastolic blood pressure will drop, and symptoms such as dizziness, blurred vision, nausea and vomiting, and impaired consciousness may occur.
5. In addition, vasculitis, infectious shock, hemorrhagic shock can also cause a decrease in diastolic blood pressure.
If you experience a decrease in diastolic blood pressure, please seek medical attention to find the cause of the problem and treat it promptly.
