Yes, an apical pulse is heard with a stethoscope placed over the apex of the heart, and is an accepted pulse measurement. It differs from an arterial pulse and is not considered as one of the accepted arterial pulse points in that it does not measure pulse being palpated where an artery passes over a bone, but rather is listened for directly over the heart.

I am manufacturing a product for college and need some type of pulsing circular lights. If anyone knows offhand it’d be a real help. thanks!

I’m 15 weeks pregnant. In the last week I’ve been having heart palpitiations, pretty frequently, certainly every hour. I spent last Thursday in the emergency room, they did an EKG when I walked in, it looked good. Drew blood, started me on fluids as I was dehydrated from morning sickness and took a urine specimin. After the fluids finished up they put me on a heart moniter (rythmn and pulse) blood pressure check every 15 minutes and blood oxygen/breath rate. Things had settled down, nothing really showed on the moniter save for a few odd beats, nothing serious. The blood/urine tests were ok. They did CBC and electrolyte panel. The only thing that showed up was some mild ketosis from not being able to keep anything down. I’ve also had episodes of after eating my pulse will speed up to 95-100 bpm and my blood pressure will be around 105/60. Low for me. At physical therapy the other day after mild excersice my bp was 112/65 (again lower than my normal.)
ER doctor wasn’t worried, didn’t feel it was life threatening. It has continued but somewhat less. Anyone have any ideas what may be causing this? I’m a 35 year old woman, 4th pregnancy within 5 years.

Ok, I know its difficult to maintain proper hydration with morning sickness. Ask your doctor for an anitemetic (scopolamine, phenergen) for days when the vomitting is really bad. Your irregular heartbeats probably came as a result of dehydration as decreased blood volume is a bit of shock to your system.
What concerns me is the increased heart rate when you eat. I have heard of this in conjunction with an ailing gallbladder.
As far as your blood pressure is concerned, pregnancy just messes with it. Generally hypertensive patients will suddenly become hypotensive and vice-versa.
Do what you can to maintain proper fluids, take your vitamins, exercise as much as you can tolerate, keep all of your prenatal appointments, eat well and dont be afraid to call the doctor or go to the ER if something isnt right. Good Luck

I need to do an experiment on pulse rate and exercise for a gcse assignment. Then need to write up a report. Any ideas on how to go about it please?
Thanks

You need to decide on your independent variable — probably the intensity of exercise in some way, or perhaps the length of time since the exercise, to see how quickly people recover. Then you will need to think about measuring your dependent variable — pulse rate. You could take a resting pulse before people start.

What form of exercise will you use, and how large will your sample group be? When you decide on the form of exercise, think about safety considerations. Will they be in a safe environment, do they have suitable footwear/clothing, are there any health considerations. What about warming up? Would you take a resting pulse before or after that? Will people have to run a certain distance, or for a certain amount of time? Or do something like star jumps, or skipping? The exercise you choose probably doesn’t matter that much, as long as you explain why you have chosen it.

In your write-up, you will want an introduction to your experiment, setting out the hypothesis you are trying to test. Then you need a methods/results section, explaining the details of your experiment, so anyone else could recreate it, and giving the results you obtained, nicely tabulated with averages and any other statistical analysis (I can’t remember what kind of statistics are commonly used at GCSE level, so be guided by your teacher.) The most important part in many ways is the discussion, in which you explain what your results mean, whether anything went wrong or could have been done better, (were there other factors influencing pulse you didn’t take into consideration?) and whether there are any further experiments that would be useful. Use other experiments you have done in class as a template.

It’s your experiment, so think about these questions, and discuss them with your teacher. Hopefully this has given you some pointers!

What is the threshold for radial/apical pulse deficit being a problem. Please include a reference to where I can find your answer in publication (preferably on the web)

A pulse deficit is the difference between the apical vs. radial pulse. A pulse deficit greater than 4 might indicate some physiological problem.

Power is the rate of energy emitted. The average is 0.2 J in 5*10^-9 s

0.2/5*10^-9 = 4.0*10^7 W = 40 MegaWatt

what could it be, I do have axiety disorder but I dont have anxiety at these times and my family has a history of heart disease, should I see a specialist or ignore it?

There are a few things it could be. 110 is not a healthy resting heart rate, you definitely should see a Dr. But you could have a heart problem. There’s a good possibility that you have SVT (Super Ventricular Tachycardia) Which is where your heart rate increases, and your heart contracts so fast that it is unable to pump blood well. I think you probably need some exercise to lower your resting rate, and you need to see a Dr. about the 160, a heart rate of 160 can cause hypoxia (low blood oxygen) to your organs such as your brain and heart.

can anyone tell me why one of the symptoms for a low pulse ox (lets say 86%) is tachycardia? if your heart beats increase wouldn’t you get more oxygen to your tissues?

If you’re asking if one of the consequences of a low pulse ox is tachycardia – well, it does make sense that the body will respond to low tissue perfusion by attempting to increase peripheral oxygen delivery, one mechanism of which is by increasing the heart rate (which may well go into tachycardic ranges, depending on your definition of what tachycardia is).

If you’re asking if one of the causes of a low pulse ox is tachycardia – perhaps the concept under concern is that of a tachyarrhythmia (eg. rapid atrial fibrillation or SVT), where an abnormal heart rhythm causes the heart rate to go abnormally fast – normal hearts may cope allright with this, but hearts that have poor reserve (eg. those with coronary artery disease) may well suffer an impaired cardiac output as a result – this can of course result in poor peripheral perfusion, hence a low pulse ox.

Hope that helps!

Just wondering as i tried my new exercise bike today and the max i could get the pulse sensor was 116bpm over 15Min’s, when im supposed to be exercising at a rate of 160bpm.

Cheers

I don’t think they’re accurate at all. In fact, I gave up on them and don’t bother using them anymore. When I used it, it would fluctuate, making my heart rate skyrocket, then drop. Half the time there wouldn’t even be a pulse. You shouldn’t rely on them too much.
