It means you need to go see a doctor, that is way too high. As a reference, stage II hypertension starts at 160/100 and you are well above that. If you are feeling lightheaded, dizzy or have a headache, go to an ER and get checked out.

It was an accurate reading. Dr today put me on blood pressure medication and cholesterol meds. also ordered tests for my heart he thinks i have heart disease
