Blood Pressure 124 over 40 - what do these values mean?
Yes, mostly. 124/40 is normal by international guidelines. US guidelines are stricter and already call it elevated, so it is worth keeping an eye on.
- International (ESH)Normal
- US guideline (ACC/AHA)Elevated
- Pulse pressure84 mmHg
- Mean arterial pressure68 mmHg
What to do now
- Small changes keep it from rising: less salt, more vegetables and fruit, daily activity.
- Re-check at least once a year.
The systolic (upper) number decides: on its own your diastolic value of 40 would be ideal (optimal). When the two numbers fall into different categories, the higher one counts.

International categories: European Society of Hypertension (ESH) 2023, office readings. Home readings use lower thresholds — hypertension from an average of 135/85.
Pulse pressure and mean arterial pressure
A pulse pressure of 84 mmHg is wide (above 60). In older adults it usually reflects stiffer arteries. Mean arterial pressure — the average pressure perfusing your organs — is about 68 mmHg (normal roughly 70–100).
Measure it right
- No caffeine, exercise or smoking for 30 minutes; empty your bladder.
- Sit with back supported, feet flat, for 5 minutes. Don't talk.
- Upper-arm cuff of the right size on bare skin, arm supported at heart level.
- Two readings a minute apart, morning and evening, for 7 days — use the average.
