It is among hundreds of artifacts linked to the doomed ship to be sold at auction later this month. 'Unthinkable': This chilling hand-drawn building plan was used to describe how the 'unsinkable' RMS Titanic met its fate.
The bottom number, called the diastolic pressure, is the measurement as the heart relaxes between beats. Normal blood pressure is a systolic pressure of less than 120 millimeters of mercury (mm Hg) and a diastolic pressure of less than 80 mm Hg, or 120/80 mm Hg, according to the American Heart Association (AHA).Having a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension.A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.aving a blood pressure greater than 140/90 mm Hg is considered high blood pressure or hypertension. A blood pressure level between normal and hypertension, is called prehypertension, meaning it is higher than normal, but not high enough to be considered hypertension.
A blood pressure measurement includes two numbers: systolic pressure (the upper number) and diastolic pressure (the lower number). These numbers are measured in millimeters of mercury, or mmHg. Your systolic pressure is high: 140 mmHg or over is high. And your lower number is normal: normal diastolic pressure is below 80 mmHg. When your systolic blood pressure is high and your diastolic blood pressure is low, itâs called isolated systolic hypertension (ISH). People with ISH do benefit from treatment, as it lowers the risk of heart disease and stroke.
