The bottom number is the more important of the two. The bottom number of your BP (104) is a bit high. That's the pressure in your blood vessels after your heart has contracted and is now at momentary rest. Average is about 80. Your upper number (128) corresponds to the pressure in your vessels when your heart contracts.
Your blood pressure reading uses these two numbers. Usually the systolic number comes before or above the diastolic number. A reading of. 119/79 or lower is normal blood pressure. 140/90 or higher is high blood pressure. Between 120 and 139 for the top number, or between 80 and 89 for the bottom number is called prehypertension. Prehypertension means you may end up with high blood pressure, unless you take steps to prevent it.
