resting heart rate:

newborn infants; 100 to 160 beats per minute
children 1 to 10 years; 70 to 120 beats per minute
children over 10 and adults; 60 to 100 beats per minute
well-trained athletes; 40 to 60 beats per minute

Typical values for a resting, healthy adult human are approximately 120 mmHg systolic and 80 mmHg diastolic (written as 120/80 mmHg).

High blood pressure (or hypertension) is defined in an adult as a blood pressure greater than or equal to 140 mm Hg systolic pressure or greater than or equal to 90 mm Hg diastolic pressure.
