why do the heart jumps?

I don't know how old you are, so I can't really answer. Irregular heartbeat can result from a number of factors:\nstress, fear, etc\nlack of sleep\nunhealthy lifestyle\nArrhythmia, which usually occurs in fit and young people (which is what I have).\nIf there is no pain or discomfort and this has been happening for a long time, it should be OK, but maybe you should consult a doctor.\nHope it helps!

Could be heart arrhythmia, irregular heart beat which is usually begnine.  If you are very worried you should consult your doctor.

First let me say I work in Cardiology so please follow up.\nWe I have never heard anyone discribe a heart spasm, so I can not offer much help. That said, it is possible to have coronary artery spasms, the are caused by many things cocaine being one of the most common and deadly. You should call 911 and go to the ER now if it is on-going. If not you should make an appointment and get seen SOON.

It stops the heart from beating.

Gravity!  the heart works harder to pump blood when you are standing!

Its your nerves.it is very common,however,chech you stress level.This happens also when under stress

My best knowledge would be excitment, which gives a boost of adrenaline, causing the heart to have to pump harder due to the adrenaline rush, causing it to sometimes skip a beat.

Yes, this is a very important question.\nIf you find your pulse rate rising dramatically during video games, you get dizzy, fell weak, and your palms become damp, you could be stressing yourself out too much.\nSome people get seizures from playing video games.\nWatch out!!

It may be panic attacks, not always a known cause as to why the occur..can be in subconscience. I'd talk to your DR

Because when you are around someone or something you "love" or "lust" for....one physical reaction is your heart racing or "skipping"...

to keep your heart pumping and the blood flowing.

It depends on how often you are having them, and what brings them on.  The cause could be anything from serious to just too much caffeine (coke or coffee?)  I have noticed that excitement, stress,  or hot weather may also have an effect on having them.\nYou should see a dr. to rule out any serious cause.  There are medications you can take to regulate the heartbeat so that you aren't aware of the palpitations.  To a certain extent, everyone has them once in a while and it is considered normal.

ELECTRICAL IMPULSES sent down by "nodes" thru conducting pathways towards the atria and ventricles.......these atria and vents r made of muscles which contract on recievin the electrical shocks........and thats when the blood moves forward\nwhen their is no impulse being sent forward........the chambers of the heart relax and get filled with blood.....\n\njust waiting for the next impulse to come by and the heart contracts again\n\nthis goes on n on till u die!

Vasovagal syncope: Also known as the "common faint," this is the most frequent cause of syncope. It results from an abnormal circulatory reflex. The heart pumps more forcefully and the blood vessels relax, but the heart rate does not compensate fast enough to maintain blood flow.

Because heart pumps oxygenated blood to the various parts of the body. When the heart stops beating the body does not get its dose of oxygen.

This answer really depends on your age, sex and risk factors.  If you are young <35 its probably nothing serious but could be your thyroid, panic attack or rarely a heart problem.  If you are older, obese, smoke etc it could be a sign of something more serious in the heart and should be further evaluated by a doctor.  Bottom line if you have already been evaluated by a doctor and had a normal EKG its probably nothing but if you are still nervous you can ask for an event monitor.

In a word, no, your heart does not stop when you sneeze. From my perspective, it is hard to even imagine what this would mean. A sneeze itself is really a very brief event, occurring in a shorter time then a heartbeat. Of course, there is the building up to the sneeze (the "ah" of the "ah-choo"), but the heart certainly does not stop beating because of this ah-ing. Check your pulse next time to prove this to yourself.\n\nAs I answer this question, I am trying to imagine just how the heart might even "know" that you are sneezing. The heart beats because a small part of it called the SA node has a "pacemaker" activity. What this means is that there is a type of electrical cycle going on that triggers beats roughly once every second. Sneezing does not change this electrical cycle, so the heart keeps beating. Said a different way, the muscle of your heart is a big mass of electrically active tissue, and this electrical activity will not stop because of a sneeze, or anything else for that matter.\n\nAnd yet, a sneeze is definitely a complex cardiovascular event. As you "ah" and "choo", you significantly change the pressure inside your chest, which in turn affects blood flow and thus the beating of the heart. Still further, I assume that a sneeze involves a significant activation of certain pathways of the "autonomic" (roughly means automatic) nervous system. These also innervate the heart and do affect the frequency and other aspects of the heartbeat.\n\nSo MAYBE the rapid culmination of these inputs OCCASIONALLY causes the heart to "skip a beat" after a sneeze. Notice I did not say "stop". We all experience skipped beats once in a while, some more than others. You may notice it as a "fluttering" in your chest, a sensation that generally evokes a bit of anxiety. What happens is that there is occasionally a discoordination of the normally organized pathways of electrical activity in the heart. Sometimes one part of the heart does not conduct the beat appropriately, or more commonly, another part actually manages to beat ahead of schedule, thus throwing the whole beat off. Either way, you get one beat that does not occur correctly. But all this means is that you have to wait for the beginning of the next electrical cycle to come around, at which time a normal, organized beat will occur (assuming that we are talking about a normal heart!). You see, the heart didn’t stop, really, since the electrical cycle was still ongoing. It just got out of synch for a while. Again, I am not actually aware that this happens with any increased frequency after a sneeze, but I suppose it is possible.\n\nTom Wilson, MD PhD \n\nhttp://www.madsci.org/posts/archives/mar98/890925984.An.r.html
