Welcome to HealthcareMagic.
Your blood pressure as of this reading is high.But it does not mean you have Hypertension
.As other reading are in normal range , its unlikely you are hypertensive.
Blood pressure when measured correctly 1 week apart , shows elevation , is considered a finding for hypertension.Even if you are tensed up while testing for BP , it can show high levels .
I advise you to get a checkup done a week later and if that value is normal you can just neglect it.
