Systolic and diastolic pressures approaching each other is a sign of pericardial tamponade which is when fluid begins to fill the sac around the heart (pericardium). This will cause pressure to increase on the heart which will decrease the pumping power of the heart. The heart will not be able to circulate the blood effectively so the body will begin to go into shock (diaphoretic extremities, increased pulse, increased respirations). As the pressure on the heart increases, the heart is working so hard that it begins to tire and could go into arrest. Cardiac arrest, if not defibrillated, will lead to death.
- Ben, NREMT-B student
it is systolic I remember it by Lub-Dub like clapping your hands.
systolic
This is impossible. Systolic pressure is the pressure in the artery during the heart contractions. Diastolic pressure is during heart relaxation. Picture this, and you'd see that it's impossible to have diastolic pressure equal or greater than systolic pressure.
stroke volume
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.
The systolic pressure is always stated first and the diastolic pressure second. For example: 122/76 (122 over 76); systolic = 122, diastolic = 76. Blood pressure of less than 140 over 90 is considered a normal reading for adults. A systolic pressure of 130 to 139 or a diastolic pressure of 85 to 89 needs to be watched carefully. A blood pressure reading equal to or greater than 140 (systolic) over 90 (diastolic) is considered elevated (high).
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.
