Systolic and diastolic pressures are vital components of blood pressure readings, each representing different phases of the heart's function during a cardiac cycle.
Systolic pressure is the higher number in a blood pressure reading and represents the pressure when the heart is contracting and pushing blood into the arteries. On the other hand, diastolic pressure is the lower number and reflects the pressure when the heart is at rest and refilling with blood.
The sound heard as the blood flows back into the artery, associated with the tapping beat, is indicative of the systolic pressure during blood pressure measurement using a sphygmomanometer and a stethoscope.
Understanding the concepts of systolic and diastolic pressures is crucial in interpreting blood pressure readings and assessing cardiovascular health.
