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.
The systolic number is placed over the diastolic number and is always the higher of the two numbers. For example blood pressure of 110 (systolic) and 70 (diastolic) is read as 110/70mmHg. The measurement of blood pressure is expressed in millimetres of mercury (mmHg). High blood pressure at rest is an indicator that the cardiovascular system is in a less than ideal state of health.
