why should you ststolic number be under 140?
"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.
Until recently, it has been 140/90. 140 is the systolic, 90 is the diastolic. Now the standards are stricter, and 130-140 and 80-90 are considered "pre-hypertension".
This is considered a high reading as your systolic should be at least under 140 and ideally under 120 mmHg. Blood pressure readings do vary a lot and also the relationship between the higher and lower numbers can change. Therefore when you measure your BP again the readings may both be normal, or they could both be raised or it might be similar to now. Taking a number of measurements over time will give you a better picture as to whether this is a one-off or not. If it persists as it is, with only the systolic number raised, you still have hypertension (though to be terminologically precise you have Isolated Systolic Hypertension). It still needs to be controlled and you should follow the usual advice - that is to try lifestyle changes first.
120/80 is normal 140/90 is high blood pressure Around age 50 the top number (systolic) can begin to rise without the bottom number (diastolic) rising, and this is called Isolated Systolic Hypertension.
That means you have high blood pressure systolic should be around 90-140 diastolic should be around 60-90
140 and above on top number (systolic), 90 and above on bottom number (diastolic). There is a relatively new term called pre-hypertension that classifies systolic pressures between 120 - 139 and diastolic between 80 - 89 in an at risk for developing hypertension category.
Systolic pressure (The top number) represents the pressure created during contraction of the left ventricle. Diastolic pressure (The bottom number) represents the pressure within the vascular system while the heart is at rest. Typical blood pressure range for an adult is: 110 to 140 (systolic) over 60 to 80 (diastolic)
blood pressure of >140 mm Hg systolic and/or >90 diastolic
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).
A good blood pressure reading for the average person is Less than 120 for the systolic (top) number and less than 80 for the diastolic (bottom) number). Blood pressures between 140-150 systolic and 90-99 diastolic are considered to be Stage 1 high blood pressure. A systolic reading of 160 or higher and a diastolic of 100 or higher is considered to be Stage 2 High Blood Pressure. Higher numbers than those are considered to be a crisis and can be life threatening.
High blood pressure is defined as consistentently elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.YOur systolic is somewhat elevated,but not high enough to be overly concerned about.
