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.
Systolic blood pressure is a measurement of the pressure on blood vessels as the heart is contracting. It is higher than that of the diastolic blood pressure, which is the measurement of the pressure on vessels as the heart relaxes and refills.
Systolic pressure is the highest pressure in the arteries after ventricular contraction. A normal value for that would be about 120 mmHg.
Diastolic pressure is the lowest pressure in the arteries just before the next contraction of the left ventricle. A normal value for that would be about 80 mmHg.
Diastolic, the bottom number in a blood pressure reading, is the pressure in the arteries between heartbeats. Systolic, the top number in a blood pressure reading, is the pressure in the arteries when the heart beats.
Systolic is the force with which blood is pushing against arterial walls during ventricular contraction whereas diastolic represents the force exerted by the blood remaining in arteries during ventricular relaxation.
What does the BP numbers mean?
The number on the top is the systolic blood pressure and the number on the bottom is the diastolic blood pressure. The systolic BP is the pressure in the arteries right when the blood is pumped out of the heart, therefore the pressure is bigger. The diastolic BP is the pressure in the arteries after the blood has been pumped out and before the next heart contraction. At this moment, the heart is relaxed and the pressure is much lower.
The systolic pressure is the blood pressure in the arteries during contraction of the ventricles.
Diastolic pressure is the blood pressure that remains between heart contractions. :)
it is systolic I remember it by Lub-Dub like clapping your hands.
systolic
The systolic number is always higher than the diastolic number. 120 or lower for systolic number and 80 or lower for diastolic is in normal range. If diastolic is high, say 95 after running - is ita high? and if what should one do?
Diastolic
Blood pressure has both diastolic and systolic readings on a meter. The expected readings of a healthy individual are below 120 for systolic and under 80 for diastolic. Diastolic measures the resting moments between beats while the systolic measures the beat. On the meter, systolic is the upper number and diastolic is the lower one.
You have long diastolic time as compared to systolic time. So diastolic time is more compromised than systolic time.
Rapid potassium infusion causes diastolic and not systolic cardiac arrest.
Having a high systolic bp is more dangerous than high diastolic bp.
The systolic and diastolic pressures are the pressure exerted against the artery walls. This will vary from person to person. There is no one answer to your question.
Your heart is about to explode and you die
The first number would be your systolic, meaning the pressure in the vessels as the heart contracts, then the next number would be t he diastolic, when the heart is at rest. The average blood pressure is around 120 over 90.
