What events in the cardiac cycle cause the first and second heart sounds?
The closing of the mitral and tricuspid valves create the "lubb" and the closing of the semilunar valves creates the "dubb"
What is the length of the cardiac cycle if the heart rate is 80 beats per minute?
To find your answer, your first step is to divide the time (in this case a minute...a minute equals sixty (60) seconds) by the heart rate (e.g. 80 beats). So---60 divided by 80 will give you 0.75 seconds. Your answer will justify the time/length of the cardiac cycle.
Should you disconnect the positive or negative battery terminal first?
Negative, that way if hit a ground while on pos bolt it wont short out.
How does myocardial infarction lead to heart failure?
Myocardial infarction (MI) can lead to heart failure in numerous ways. First of all, early on, the heart muscle does not contract well because it is not receiving enough oxygen and other necessary substrates, so stroke volume is decreased, which may lead to congestive heart failure. Later on, if the MI is aborted with thrombolytics or with a cardiac catheterization and thrombectomy, the myocardium may be stunned, or hibernating, because of the lack of oxygen, and may return to normal function over time. If the MI completes, the portion of cardiac muscle that was affected is dead. Depending on how significant a portion that is, losing the muscle alone may result in heart failure. The dead portion of the heart will later turn into a scar, which is noncontractile and also does not allow for the normal stretch, so it may affect preload and contractility in that way as well, decreasing cardiac output and possibly leading to congestive heart failure.
What is Another name of heart?
The word heart is a noun, a singular, common noun; a concrete noun as a word for an organ of the body; an abstract noun as a word for the central, most important part or the center of a person's thoughts and emotions.
Is the p wave part of the cardiac cycle?
Yes - On an ECG the P wave is the first wave of the cardiac cycle. It represents the Sinoatrial node which is the natural pacemaker of the heart firing and causing the atria to contract in order to fill the ventricles.
Cardiac cycle when do you hear the first heart sound snd second?
when the ventricles closes and between the atria and the ventricles.
What is occurring during the diastolic period?
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
When you start your period is it a normal cycle at first?
Usually not at first but sometimes it is irregular for quite some time
Is it normal for your period to be behind a few weeks if you startd for the first time the month before?
no, it is normal. when you start your period for the first time it takes a year or two to become a normal cycle.
The first sound of a cardiac cycle occurs when?
closure of the mitral and tricuspid valves.
You have bleeding after 32 days of your cycle but it is different and less. How can you tell whether you are pregnant?
If 32 days is your normal cycle you may be just having a light period. If your cycle is normally shorter then you may be pregnant and just having a bit of spotting. Buy a home pregnancy test from the pharmacy and do a home pregnancy test with the first urine you pass in the morning. If it is negative and you still haven't had a normal period in a week do another test. If you are worried go to the doctor.
What events in the cardiac cycle cause the first and second heart sounds?
The closing of the mitral and tricuspid valves create the "lubb" and the closing of the semilunar valves creates the "dubb"
If you spotted the first two days of your cycle and had a normal period after could you be pregnant?
you are not supposed to have a period if you are pregnant.
What is the length of the cardiac cycle if the heart rate is 80 beats per minute?
To find your answer, your first step is to divide the time (in this case a minute...a minute equals sixty (60) seconds) by the heart rate (e.g. 80 beats). So---60 divided by 80 will give you 0.75 seconds. Your answer will justify the time/length of the cardiac cycle.
What happen when you divide negative and positive number?
When you divide or multiply positive and negative numbers, you first do the division or multiplication as normal. The next step is to assess whether or not the answer will be negative or positive. If the two numbers of the question were the same (negative and negative or positive and positive) then the answer will be positive. If the two numbers in the question were different (one negative and one positive) then the answer will be negative. Thus, if you divide a negative number by a positive number, the result will be the same as normal division, but the answer will be negative.
Is it normal for your period to not come on the exact day it came the first time?
Yes, it is quiet normal, you may even miss a period. But but be alerted if you miss more than one or if the duration changes to a very short cycle or a very long cycle.
