Frequently asked questions
What do the two numbers mean?
In 120/80 mmHg, 120 is the systolic pressure (the top number), when the heart contracts, and 80 is the diastolic pressure (the bottom number), when it relaxes.
Does one high reading mean hypertension?
No. A diagnosis depends on several readings, on different days, taken the right way (seated, at rest, with no coffee or smoking beforehand). Only a doctor can confirm it.
When should I seek care?
A reading of 180/110 or higher, or any high reading with chest pain, shortness of breath, a severe headache, confusion, or changes in vision or speech, is a reason to go to emergency services.
