By diagnosis!
Systolic blood pressure (the top number) tells you how strong the pressure is when your heart beats. A higher top number is usually more cause for concern that the lower number.
Diastolic blood pressure (the bottom number) tells you how strong the pressure is when the heart is not beating. What this generally tells you is how elastic and resilient your system of vessels are. With age, this number gets lower- particularly after middle age.

There are a number of factors that can cause a high diastolic reading. These include, but are not limited to, stress, poor diet, obesity, sedentary lifestyle, age, smoking, and alcohol. A high diastolic reading with a normal systolic reading is known as isolated diastolic hypertension. If the diastolic reading is not brought down soon, higher systolic readings can follow. It is important to discuss any abnormal blood pressure readings with your doctor.
Diastolic will be higher in people with lots of cholesterol or plaque buildup. It measures the pressure resistance between heartbeats rather than at the peak of each beat, so when the system is full of cholesterol or plaque it causes resistance to the pressure of the heart's pumping. Exercise 3 times a week for 30 minutes can bring down this number. Cutting out red meats, bacon, mayo and other sources of fat and eating oatmeal and other fiber-rich foods can also help bring it down. Alternative health supplements make many claims, but there is some indication out there that replacing those fats you eliminated with fish oil, flax, hemp oil, pumpkinseed oil, olive oil, etc can help. Some people take Red Yeast Rice which has a natural form of something like statins, but they don't work much at all unless you are exercising and changing your diet. Exercise and water are "the first medicine", vegetables the second, and everything else third.
Resting blood pressure for a male (optimum) is 120/70. It will be elevated after exercise or a stressful event.
"Normal" blood pressure is somewhere between 90/60 and 140/90. Systolic - the top number Diastolic - the bottom number Systolic pressure is when the heart is contracted and squeezing blood out of the heart. Diastolic pressure is when the heart is relaxed and letting blood flow into the heart.
When a person is evaluated for high blood pressure), 2 values are recorded: systolic and diastolic blood pressures. Systolic (the higher number) is the pressure in the arteries when the heart contracts; diastolic (the lower number) is the pressure when the heart rests between contractions. A blood pressure reading is recorded as systolic /diastolic pressure, or "systolic over diastolic." Both systolic and diastolic blood pressures are measured in millimeters of mercury (mmHg). An example of how to read a blood pressure measurement is "120 mmHg/80 mmHg" or "120 over 80." High blood pressure in adults is defined as having either a systolic pressure of 140 mmHg or more, or having a diastolic pressure of 90 mmHg or more. In some people with high blood pressure, both systolic and diastolic pressures are high. However, older people often have a higher systolic pressure with a normal. This condition is called isolated systolic hypertension, which is still considered high blood pressure. In older adults because the arteries reduce in elasticity, they do not expand as easily causing an increase in the systolic blood pressure (Imagine the same quantity of blood flowing through a vessel that doesn't expand. It gets really crammed in there causing systolic blood pressure to increase). But because diastolic pressure is the minimum pressure exerted on the arteries during diastole, there isn't much distension and contraction of the arteries. Thus, reduced elasticity does not effect diastolic pressure causing a normal blood pressure reading.
Your systole and diastole (or systolic and diastolic pressure). Systolic pressure is the pressure your blood exerts on blood vessels when your heart pumps out blood while diastolic pressure is the pressure your blood exerts on blood vessels when your heart is at rest(in between pumps). Blood pressure is stated as systolic pressure/diastolic pressure. The normal BP is 120/80 mmHg.
Systolic under 120, Diastolic below 80
Normal systolic from 121-147 Normal diastolic from 83-91
The systolic pressure is always stated first and the diastolic pressure second. For example: 122/76 (122 over 76); systolic = 122, diastolic = 76. Blood pressure of less than 140 over 90 is considered a normal reading for adults. A systolic pressure of 130 to 139 or a diastolic pressure of 85 to 89 needs to be watched carefully. A blood pressure reading equal to or greater than 140 (systolic) over 90 (diastolic) is considered elevated (high).
Normal blood pressure levels are around 120 systolic and 70 diastolic. But the safe zone starts at 90 (low normal) up to 140 (high normal) on the systolic and 60 (low normal) up to 90 (borderline) with the diastolic. Much of it also depends on the individual and their height and weight as well.

I found this on http://healthfullife.umdnj.edu - Optimum blood pressure - less than 120 millimeters of mercury systolic and less than 80 millimeters of mercury diastolic - Normal blood pressure - 120 to 129 millimeters of mercury systolic, 80 to 84 millimeters of mercury diastolic - High normal - 130 to 139 millimeters of mercury systolic, 85 to 89 millimeters of mercury diastolic
yes but maybe a little low in the systolic pressure
The systolic number is always higher than the diastolic number. 120 or lower for systolic number and 80 or lower for diastolic is in normal range. If diastolic is high, say 95 after running - is ita high? and if what should one do?
