– Systolic and diastolic blood pressure are both very important. There was a period many
years ago where doctors felt the diastolic blood pressure
was the more important of the parameters, but we treat both. The systolic blood pressure
is the pressure that is felt when the heart is beating. And they diastolic blood
pressure is the pressure that is felt when the heart
is at rest between beats. The systolic is the top number, and the diastolic is the lower number.
