Not unless you have associated symptoms.Heart palpitations can be caused by numerous things,some being:\nExercise\nAnxiety, stress, fear \nFever\nCaffeine, nicotine, cocaine, diet pills \nOveractive thyroid\nAnemia \nThere are of course many others. As someone who suffers from an Arrhythmia,try some of these.I rule out coffee,chocolate,coca-cola, pepsi,and smoking.These do  help.\nReducing stress and anxiety can help lessen your heart palpitations. Try breathing exercises or deep relaxation (a step-by-step process of tensing and then relaxing every muscle group in your body) at the time of your heartbeat sensations. Also, consider practicing yoga or tai chi on a regular basis to reduce the frequency of your palpitations.\nKeep a record of how often you have palpitations, when they happen, how long they last, your heart rate at the time of the palpitations, and what you are feeling at the time. If you have never had heart palpitations before, bring them to the attention of your doctor. He or she will do a work up to determine the cause and whether they are treatable or not.\n Things to watch for.\nYou feel frequent extra heartbeats (more than 6 per minute or coming in runs of 3 or more).\nYou have new or different heart palpitations.\nYour pulse is more than 100 beats per minute (without exercise, anxiety, or fever).\nFrom what you say,I feel your stress is the cause of your problem. Try to ease your stress levels, or see your doctor for help .

Yeas, see a doctor pronto.  This is your body's way of saying "Hey, Mr. Brain isn't getting enough oxygen right now!".  Possible causes could be medication, hypotension, a blocked carotid artery, a serious heart condition, etc.  Only testing will tell!

theyre probably PVCs or PACs (premature ventricular/atrial contractions). basically, a cell in the heart fires to early which makes it beat twice really fast, then your heart pauses for a brief second to allow itself to get back on track. i get hundreds to thousands of them a day, it kinda sucks. 10+ a minute when they are really acting up. lots of people get them and theyre completely harmless in most people, but you may want to consider getting checked out sometime because they can occasionally be symptom of other problems. but im not trying to scare you, most lof the time theyre harmless, as mine are. some of the common causes are too much caffeine, lack of sleep, smoking or drinking, and stress. but some people like me just get them for no reason. if youre getting a lot and they really bother you, the doctor can put you on a beta blocker which helps reduce them in some people. you can browse through old questions in the heart forum at medhelp.org lots of people have asked questions on them and you can learn a lot from reading the answers

It may be a vagus nerve disorder rather than cardiac.  Go to the internet and read about vaso-vagal fainting to find further information.

Most likely is gas, problems with the heart are pressure in the chest not pain, I would take him to a doctor as soon as possible just to make sure he's fine..☺

You may have PSVT which is a fast heart rate. It is very annoying and is scary when you feel it. It is treatable though. Do you drink /eat a lot of caffiene? (Cokes, tea coffee, chocolate?) Ask your doctor to put a Holter Monitor on you and see if anything shows up there. It is a 24 hour monitor you wear and it monitors your heart.  Good luck!

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

What you are experiencing is not a murmur, it is "palpitations".  It probably is an irregular heart beat, possibly something called "premature ventricular contractions" or "PVC's", but only a doctor can tell you for sure.  This is something that I would definitely see a doctor about.\n\nPVC's can often be greatly reduced by staying off caffeine and certain medications.  PVC's are only one possible cause of palpitations though.  You really should get this checked.\n\nYou can learn more about PVC's here:\nhttp://en.wikipedia.org/wiki/Premature_ventricular_contraction

Actually someone may have suggested to you that you may have heart problems,  You have gone through the tests and nothing has showed up.  If there was a problem believe me you would have been notified or admitted to the hospital from the emergency room.\n   Now you are dealing with a little anxiety, better address this problem before it starts ballooning into full scale panic attacks. \n   Trust in the doctors diagnosis, If you still are not convinced get a second opinion, make sure you also submit all your lab work and tests  so the new doctor has something to work with.\n   Just kick back smile and say to yourself It wasn't a heart attack or I wouldn't be sitting here right now.

Well in my case I felt the standard stabbing pain in my chest and a numbness in my left arm, it felt like someone was standing on my chest,couldn't breathe, couldn't hardly move. Broke out in a cold sweat and a feeling that is hard to explain, helplessness came over me. Fear, I knew what was going on, I wasn't afraid honestly ,I thought it was time to check out, my family met with me at the hospital, my brothers, and we talked and even laughed about all the things we had done as kids, I could see fear in thier eyes, I tried to make it easy on them. This was a "Minor" heart attack, it did however do some muscle damage to my heart, and I have suffered 2 more in the last 8 years, all required hospital time. My problems however are not blocked arteries mine is caused by a-fib, an extreme electrical short in the heart. I have been told a pacemaker would be the next step, I am just not sure about having "The Energizer Bunny" regulating my heart beat. You only fear death my friend if you are not sure what awaits you there, I know....and there is nothing to be of afraid of there.\n\nBlessings

The lightheadedness and difficulty breating can be side effects of the racing heart. If ur not having panic attacks, u should go to ur dr and find out what is making ur heart race.
