PLEASE HELP?What effect would holding your breath have on your pulse rate?

Decrease because there is less oxygen. I think.

I have seen this make a person's heart rate drop close to a fatal ending at where I work.. Please stop taking it and tell your doctor and demand something else in its place..

unsteady breathing. Breath slow and steady deep breaths and stay calm and you will keep you heart rate down. If youve ever watched a military movie where the soldiers sing to a beat while running use that it puts your whole body to a rhythm which keeps your body calm.

Hold your breath as long as you can, it really works try it!

Your heart is not controlled by sound.  If you hear a particular sound and your brain interprets it in a way that makes you stressed or excited, your heart rate may go up.\n\nAn example of this would be hearing a siren right behind you when you are driving - that will make most people's heart rate increase.\n\nHeart rate is controlled by your sympathetic nervous system.

you'll get the same results.....the whole point is to get your heart rate elevated for a long time...doesn't matter if you swim/run/jump/workout....=]

Increase because the brain thinks that by increasing the heart rate will bring it more oxygen.  Same thing happens whenever the brain is starved for oxygen, such as in carbon monoxide poisening.

The basic heartbeat is controlled by cells in the heart which have leaky membranes-Ions leak in, and depolarize the cell, which then causes a rapid spreading contraction.  Thus, the brain does not control basal heartrate.  The brain, through mediation of the sympathetic and parasympathetic nervous system can, however, modulate the rate of the heartbeat.  There are some specific loci which are associated with these systems, but the most potent is the emotive centers of the brain, which in turn are regulated by the cerebral cortex (the "thinking" part of your brain), which is why, when you are told you just flunked a test, your heartbeat rises, while when you listen to relaxing music, your heartbeat slows.  The conscious part of your mind sends signals to the emotive centers, which then regulate the symapthetic and parasympathetic system.  But, cutting off your head will not stop your heart from beating...at least not until the heart itself runs out of oxygen because of the lack of breathing.

heavy and vigorous exercises increases the demand of oxygen thereby increasing the breathing rate 20-25 timesper minute.Otherwise it is 18-20 times.Certainly not, the effect will be different to different people. an asthematic person may have have even more effect of it. it may be either a rapid increase in breathing rate or problem in inhalation. adults(70-80) have also somewhat effect too.this increases their blood preesure pulse rate and chances of heart failure.

i am taking one tomorrow.  they hook you up.  make you walk, then gradually increase speed on a treadmill.  if your heart rate gets to a certain poinit it stops.  if your heart shows any signs of weakening it stops.

Let me preface this: I'm not a medical professional; I have taken several anatomy classes that give me a basic background. I can't speak for every case, but here's my two cents on the subject. The vagus nerve innervates the heart and provides input into the speed of the heartbeat. It also branches into a few organs in the abdomen, but its primary purpose is to affect heart rate. The heart has its own internal pacemaker which beats around 100 beats/min at rest. The vagus stimulates the heart to actually beat SLOWER than it otherwise would. The better physical fitness, the slower it beats at rest because the heart is more efficient.\n\nIf the vagus were to be blocked, all communication below the blockage would essentially stop (for example when someone has an injury where their spinal cord is severed, doctors can tell exactly where the sever happened based on what functions and what doesn't). I'm not familiar with blockages of nerves, per se. There are ways that nerves can be damaged or severed, resulting in loss of communication above and below the damage. So it would depend largely on the degree of nerve damage/blockage and where exactly it occurs.\n\nTo actually get to your question, I do not know if vagal nerve blockage would cause high blood pressure. High blood pressure is related to a decreased level of elasticity in the blood vessels (primarily the arteries). With every beat of the heart, the arteries expand from the increased pressure. When they are less flexible (from arteriosclerosis or atherosclerosis, for example), blood pressure increases. Blood pressure can also increase with exercise (the heart tries to pump more blood through the body faster). Assuming that the vagus would be damaged above the heart so that it doesn't tell the heart to beat slower, there's a chance it could affect blood pressure: a chronic fast heart rate may affect elasticity of the arteries. The arteries would not have as much time to relax/contract between each beat. It's possible, but I don't know.\n\nAs for vomiting, it may or may not affect it. I don't know which other organs the vagus affects. It is quite possible that at least one of them is related to digestion. Also, the fast heart rate (and probably a feeling of fluttering heart beat) could make you light headed or nauseaus. Whether you actually vomited from it would depend on how that affects you.\n\nSorry I couldn't provide any solid answers, but I hope the background info gives you some help.

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.

less respiration ocurring and less exsercise and stuff should decrease it and also it depends how in shape the person is so it would take less pumps of the heart to make the blood flow. So if a marathon runner was currently asleep the heart rate would be low compared to a 5-time pie eating contest winner that was over weight and just ran a mile.

After 5 minutes your brain will have some damage due to oxygen depravation, and you possibly be left in a vegetative state.\n\nThat is my answer.\nHowever, my sister when she was born went 8 minutes before breathing and she is perfectly healthy in everyway.

It can affect your HEART...seriously...my mom is a dental hygenist and has told me about it numerous times!!!  Go to a dentist A.S.A.P.!!!!!!

Warm, strange, exciting!\n\nApart from not knowing when to breathe, it's a bit like learning to drive. A whole new level of fun, but your coordination is dreadful and response time all over the place.

Has to do with oxygen demand.  During exercise your heart rate goes up because oxygen is being used much faster.  The faster pulse gets blood and oxygen to tissues faster.\n\nWhen you stop exercising, there is less demand for oxygen so the heart rate goes back down.  If it stayed high, it would cause high blood pressure and damage the vessels.
