Blood pressure is the pressure of the blood pushing against the walls of your blood vessels. The top number (systolic) is the pressure during a heartbeat. The bottom number (diastolic) is the presurre between heatbeats or at rest --R Jackson LPN
I take it you mean on your blood pressure readings? The bottom number is the pressure the blood is returning to the heart.
A blood pressure reading consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). The systolic pressure measures the pressure in the arteries when the heart beats, while the diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. The third number, if present, is the pulse pressure, calculated by subtracting the diastolic pressure from the systolic pressure. This number gives an indication of the force the heart generates with each contraction.
Systole is the top number of a blood pressure reading. It is the heart contracting forcing blood out. Indicated by the first heart sound. Diastole is the bottom number of a blood pressure reading. It is the heart relaxing bringing blood back in.
That reading would indicate a high blood pressure, 120 over 80 would normal.
Just on the High blood pressure reading. Click on "Blood pressure" under "Related links" below.
A blood pressure reading of 122/66 mmHg indicates a systolic pressure of 122 mmHg (pressure in the arteries when the heart beats) and a diastolic pressure of 66 mmHg (pressure in the arteries when the heart is at rest between beats). This reading falls within the normal range for blood pressure.
Hypertensive stands for "high blood pressure" A reading of this sort could be anything above 175 systolic (blood being pumped from the heart around the body)
The blood pressure when the heart is contracting. It is specifically the maximum arterial pressure during contraction of the left ventricle of the heart. The time at which ventricular contraction occurs is called systole. In a blood pressure reading, the systolic pressure is typically the first number recorded. For example, with a blood pressure of 120/80 ("120 over 80"), the systolic pressure is 120. By "120" is meant 120 mm Hg (millimeters of mercury).
"Diastolic" refers to the phase of the heartbeat when the heart muscle relaxes and fills with blood. It is the lower number in a blood pressure reading and represents the pressure in the arteries when the heart is at rest between contractions.
The Diastolic Pressure, is the lowest pressure in an artery in the moments between beats when the heart is resting. http://www.netdoctor.co.uk/health_advice/examinations/measuringbloodpressure.htm
BP 80P typically refers to a specific type of blood pressure measurement, indicating a reading of 80 mmHg for diastolic pressure, which is the pressure in the arteries when the heart rests between beats. The "BP" stands for blood pressure, while "80P" signifies the diastolic value. In a complete blood pressure reading, it would usually be accompanied by a systolic value, such as "120/80 mmHg," where 120 represents the systolic pressure.
The Systolic number is the force of the blood on the artery walls as the heart contracts. The Diastolic is the pressure when the heart is resting in between beats. The mmhg is how the pressure is measured, which is in millimeters of mercury.
