Every blood pressure reading gives you two numbers, and both matter. Understanding what they mean is one of the simplest ways to take an active role in your heart health.
The top number: systolic pressure
The systolic number measures the pressure in your arteries when your heart beats and pushes blood out. It's the larger of the two numbers and the one most often discussed.
The bottom number: diastolic pressure
The diastolic number measures the pressure in your arteries when your heart rests between beats. Lower is generally better here, within a normal range.
General categories
As a general guide: a normal reading is typically below 120/80. Elevated readings sit slightly above that. Higher and more sustained readings may indicate hypertension. These are general ranges only — your physician will interpret your numbers in the context of your full health picture.
One high reading isn't a diagnosis — blood pressure naturally varies throughout the day. Patterns over time are what matter most.
Why consistent monitoring matters
A single office reading only tells part of the story. That's why our 24-Hour Blood Pressure Monitor gives a fuller, more accurate picture — tracking your numbers automatically through a full day and night of normal activity.
When to talk to your doctor
If your readings are consistently elevated, or if you experience symptoms like headaches, dizziness, or chest discomfort, speak with your physician. They can determine whether further cardiac testing is appropriate.
