Both Diastolic and Systolic are derived from the Greek word. Diastolic meaning drawing apart and Systolic meaning a drawing together.
Types of Blood Pressure
- Systolic Blood Pressure.
The normal range of systolic blood pressure should be 90 – 120 mm Hg.
- Diastolic Blood Pressure.
The normal range of diastolic blood pressure should be 60 – 80 mm Hg.
Differences Between Systolic and Diastolic Blood Pressure
|Systolic Blood Pressure||Diastolic Blood Pressure|
|When the blood pressure is highest or when the heart beats (heart muscles contract), the systolic pressure is generated.||When the blood pressure is minimum, it is called diastolic blood pressure. Diastolic pressure is produced between the beats or at the resting of heart muscles between the beats, this is the time of refilling the blood.|
|The systolic stage occurs when the left ventricle gets contracted.||The diastolic stage occurs when the left ventricle gets relaxed.|
|90-120 mm Hg in adults; 100 mm Hg(6-9 years); 95 mm Hg (infants).||60-80 mm Hg; 65 mm Hg (6-9 years); 65 mm Hg (infants).|
|Undergoes fluctuations prominently during great working, the force of the heart working.||Few fluctuations are observed, but when the diastolic pressure increases, it indicates heart failure.|
|The higher number is systolic readings, and monitoring is essential with the increasing age.||The lower number is the diastolic pressure, and monitoring is important at a younger age.|
The blood pressure reading is measured in millimeters of mercury (mmHg) and is written as systolic pressure, the force of the blood against the artery walls as your heart beats, over diastolic pressure, the blood pressure between heartbeats. For example, a blood pressure reading is written as 120/80 mmHg, or “120 over 80”. The systolic pressure is 120 and the diastolic pressure is 80.
