Why is there fat around the heart?
It provides protection against trauma but also lubricates the organ for its systolic (pumped) cardiac movement and for its diastolic cardiac relaxation.
Identify the phase of the cardiac cycle to each of the following systolic pressure and diastolic pressure?
Systolic Pressure occurs during ventricular ejection.Diastolic Pressure occurs during ventricular relaxation.
What part of blood pressure denotes the force exerted on the arterial walls during cardiac contraction?
The force exerted on the arterial walls during cardiac contraction is systolic blood pressure. In contrast, diastolic blood pressure is the force exerted during cardiac relaxation.
Given an end diastolic volume of 150 ml an end systolic volume of 50ml and a heart rate of 60bpm the cardiac output is what?
600 ml/min
Is the mean arterial pressure equal to the average of systolic pressure and diastolic pressure?
Mean Arterial Pressure (MAP) is the mean of pressure you would obtain if you took measurements in several intervals during the cardiac cycle. Ex. systolic pressure + 2x Diastolic pressure/3 120/80= 120 + 2(80)/3= 93mmHG ( approximately)
How do you calculate mean arterial pressure?
MAP = [ (2 x diastolic) + systolic ] divided by 3.how you calculate
Increased heart rate causes systolic pressure to increase or decrease mean arterial pressure?
Mean arterial pressure can be thought of as 1/3 systolic + 2/3 diastolic since the heart spends slightly more time is diastole (rest) that it does in systole (contracting). MAP = 1/3 systolic + 2/3 diastolic. Therefore, an increase in either systolic or diastolic will increase the MAP. Additionally, under physiological conditions, an increase in heart rate will increase blood pressure. Increased HR leads to increased cardiac output, among other things, which increase blood pressure.
True or false stroke volume equals cardiac output X heart rate?
False. Stroke Volume (SV) = EDV - ESV (EDV) Ending Diastolic Volume (ESV) Ending Systolic Volume
Is there a pulse rate chart online?
This is a common practice if you are following up on any type of cardiac intervention. Generally speaking, simply writing down your pulse, systolic and diastolic pressure readings will be sufficient when presented to your physician.
Why is my diastolic Blood pressure higher than my systolic Blood pressure?
Systolic pressure increases during exercise because the heart activity is greater (heart is beating faster). Since heart rate is increased (as well as respiration (breathing) probably too), pressure increases with it to help increase oxygen flow both to the hear and the break and the body so it takes longer for lactic acid to build up. Diastolic pressure should either remain the same or even decrease due to vasodilatation (width increase in veins) in the exercising muscles.
Phase of the cardiac cycle that shortens most in response to tachycardia?
diastolic
What is the difference between stroke volume and ejection fraction?
STROKE VOLUME(SV) is the volume of blood pumped by ventricle during each contracion/cardiac cycle SV=END DIASTOLIC VOLUME - END SYSTOLIC VOLUME EJECTION FRACTION(EF) is the fraction of end diastolic blood pumped by ventriclea during each contraction EF=SV/EDV
