The format is binary and consists of four sections: 1  The lead, which identifies the file as an RPM file and contains some obsolete headers. 2  The signature, which can be used to ensure integrity and/or authenticity. 3  The header, which contains metadata including package name, version, architecture, file list, etc.
When your heart beats, it contracts and pushes blood through the arteries to the rest of the body. This force creates pressure on the arteries. This is called systolic blood pressure. A normal systolic blood pressure is below 120.A systolic blood pressure of 120 to 139 means you have prehypertension, or borderline high blood pressure.Even people with prehypertension are at a higher risk of developing heart disease.his is called systolic blood pressure. A normal systolic blood pressure is below 120. A systolic blood pressure of 120 to 139 means you have prehypertension, or borderline high blood pressure. Even people with prehypertension are at a higher risk of developing heart disease.
Doing so can decrease the likelihood of developing heart disease or having a stroke. Systolic blood pressure is considered high when it's 140 or above. When the lower blood pressure number is less than 90, treatment is generally considered only when systolic blood pressure tops 160. Among older patients, the evidence isn't yet clear that the pros outweigh the cons of treating it in the 140-160 range.
