First, keep the original readings from different dates and times of day, and note the measurement posture, rest status, recent sleep, mood, activity, and whether medications were taken on schedule. Do not pick only the highest or lowest single reading, and do not adjust medications on your own. You can first contact your primary care provider, cardiology, or the original care team, and let a professional determine whether repeat measurements, device verification, or further tests are needed.
