WHAT IS THE DIFFERENCE BETWEEN SYSTOLE AND DIASTOLE?
Comparison chart
Diastolic | Systolic | |
---|---|---|
Definition: | It is the pressure that is exerted on the walls of the various arteries around the body in between heart beats when the heart is relaxed. | It measures the amount of pressure that blood exerts on arteries and vessels while the heart is beating. |
Normal range: | 60 – 80 mmHg (adults); 65 mmHg (infants); 65 mmHg (6 to 9 years) | 90 – 120 mmHg (adults); 95 mmHg (infants); 100 mmHg (6 to 9 years) |
Importance with age: | Diastolic readings are particularly important in the monitoring blood pressure in younger individuals. | As a person's age increases, so too does the importance of their systolic blood pressure measurement. |
Blood Pressure: | Diastolic represents the minimum pressure in the arteries. | Systolic represents the maximum pressure exerted on the arteries. |
Blood Pressure reading: | The lower number is diastolic pressure. | The higher number is the systolic pressure. |
Ventricles of the heart: | Fill with blood | Left ventricles contract |
