What causes you to feel your heart beating & thumping loudly against your chest sometimes?

if you feel in danger or nervous than your body prepares you to run...this means your heart rate will increase ready to keep a good supply of oxygen to your muscles. this is normal, although you don't want it to happen to much as it can cause problems...if your worried at all than go and see a doctor.

I'm not saying that this is what it is....but sometimes it can be something related to your heart. Your heart is beating so fast that you sweat. It could be hormones....making you have hot flashes...it could be an electrolyte imbalance. All of which are important and I would consult your MD.

Many people have heart palpitations. Kudos to you for managing to take the risk factor smoking out of the picture!! \nNow all you need to do is monitor your palpitations. The American Stroke Society recommends taking your pulse for 1 - 2 minutes once a month. Maybe do it on the first of every month?! \nI am mentioning the American Stroke Society and not the Cardiologists because one of the most biggest problems arising from palpitations is that they can turn into Atrial Fibrillation. That is a very fast, very erratic heartbeat that you can feel in your pulse. When the heart gets off beat like that, you run a high risk of getting a small blood clot in your heart from the also erratic blood movement that will be pushed out of the heart, often straight into the lungs or brain, causing a lung embolism or a stroke. And trust me, you want neither! \nIf you feel your heart beats really erratic, go and get an ECG written, that´s a quick, simple and cheap way of checking what´s going on. \n\nOf course, this is the worst case scenario. For the moment you are most likely fine since many, many people have palpitations and for most they´ll just stay palpitations so you don´t need to worry. But you have to be aware of the possibility of them turning into something more serious. \nHope that helped :-D\n\nBy the way, if you feel your heart starting to be a bit erratic there are 2 great and fast ways to get it back to a more slow and normal rhythm that sound way too simple to be true but work great:\nOne is to hold your breath and "press" as if you´re going to the bathroom for a couple of seconds. This is not recommended for people with high blood pressure though :-D\nThe other one is drinking a glass with really cold water. Go ahead and try it, it is also recommended by the American Heart Association :-D

I have this same problem and I'm only 20 years old. I did got to the doc and had and ecg, ekg and I had to wear a heart monitor for 24hrs. Thats when the doc noticed I had an irregular heart beat. The doc told me not ot worry Its normal In some people but It's really scary. Dont ever let them tell you youre to young and Its just strees. Go have all the proper test done and If they come back normal then try not to worry so much because heart palpitations are normal. So good luck and I hope everything goes well.

because your heart stops beating for a second.

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

Actually, it sounds like you're having anxiety attacks.  The symptoms of anxiety attacks often mimic heart attack symptoms and can, therefore, be really frightening.  It's sad that there's a doctor who doesn't seem to take you seriously and who makes you feel like you're just imagining your symptoms.  My advice is to find another doctor and specifically ask about anxiety.  There are medications that can help.

Irregular heart beats and palpitations are two entirely separate entities.\nIrregular heart beats premature, fast, or slow beats and are caused by an electrical "glitch" in the heart.  They are often benign, meaning they won't harm you.  They can occur because of drugs, including caffeine, diet pills, supplements, etc, because of medical problems such a high thyroid levels or electrolyte imbalances, because of significant medical problems, and also without any apparent "reason".  The medical tests performed for irregular heart beats includes EKGs, holter monitors to record your heart rhythm, event monitors and more.  These tests are performed to find out if there is a cause of the irregularity that needs to be "fixed".  The results are also used to predict whether any harm is likely to come to you, because of the irregular rhythm.  Many irregular rhythms do not require any treatment.  \nPalpitations are the SENSATION that your heart is beating too fast, too hard, too slow, or irregularly.  You can have palpitations with a totally regular heart rhythm.  They can also be caused by irregular rhythms, both dangerous ones AND non-dangerous ones.  Some people have palpitations because of anxiety, even if they don't actually feel anxious, anxiety can cause palpitations in these people.

Things with stimulants like caffeine and ephedrine (should be off the market) and pseudo ephedrines can cause the feeling of palpitations

The term is a "premature ventricular contraction"  (aka PVC).  It is common and benign.  Although it feels like your heart stops, the large part of your heart actually beats earlier than it was supposed to have....then the signal comes through to tell it to beat...but it doesn't beat because it needs to reset after having just beat....then there is a slight pause until the next signal comes down telling it to beat.  It resumes completely normal function thereafter.  If you have many of these episodes or if you become light-headed or dizzy with them, then you should get it checked.  Otherwise it requires no medical attention.

Please see a doctor.  Yes, it could be something besides cardiac problems - and that is very, very likely.  But in some people, especially females, heart attacks don't follow a "traditional" pattern of clutching your chest and dropping to the floor.  Nobody can make a diagnosis online, not even a doctor.  Odds are, it's nothing to get worked up about - but please see a doctor to be sure.

I get them too, and I seem to notice them at the same time you do -- maybe it's because we are finally resting or whatever, so they seems to stand out compared to when we are rushing about during the day.  I was told they can be from anxiety even if you aren't feeling especially anxious at that particular moment.  I got scared when they kept happening to me, and that's what my doctor said she thought was causing it.  If you have had an EKG, though, I think you are pretty safe.  I'm sort of glad to know I'm not the only one!

How often does this happen?  It's important to take chest pains very seriously, they could be signs of a heart attack or stroke.  Is it hard to breathe?  You should see a doctor ASAP, at least to rule out any heart issues.  I'm a nurse so please take my advice.\nYou'll be okay sweetie.

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.

sounds like either a panic attack or sleep apnea (holding your breath while sleeping) both of which are very common\n\nsleep apnea tends to happen more frequently than once a year but can be very dangerous if it continues or gets worse in a person that isn't treated for it.\n\npanic attacks are common as well-nightmares can sometimes trigger them during sleep.\n\nsymptoms of a panic attack are:\n\n-palpitations (racing heart)\n-overwhelming feeling of panic or feeling like you are going to die\n-shortness of breath\n-chest pain or tightness\n-sweating\n-dizziness or faintness\n\nif you have any of those symptoms-best thing to do is lie down in a comfortable,dark,quiet room. place a cool washcloth on your forehead and focus on taking slow, deep breaths (this will help slow your heartrate down). get something cool to drink and take small,frequent sips. remain lying down until you fall asleep or feel calm enough to get back up.\n\nif this happens again in the near future-make an appt with your family dr. there are medications that can be given at night to help you sleep and ward off the panic attacks and there are also medications and methods to treat sleep apnea if you have it.\n\ngood luck
