Do I have an arrhythmia, nervous system problem?

You mention that you have seen several doctors and had several tests, but have you been to a Electrophysiologist ? This is a cardiologist who only specializes in diseases and disorders relating to arithmia's.While there may be several causes to your symptoms sometimes the only way to find out difinitavly what may be causing these fluxuations in your heart rate are two tests,one is what they simply call a tilt table test.simply put they strap you down to a table (only so you won't fall) and they monitor your vitals laying completly flat and start to tilt the table both forward and backwards (as if they were tipping you up side down)this is often done when your sypmtoms are caused when you go from sitting to standing.this could be caused also by a sudden drop in blood pressure from standing,the other test is is a Electrophysiology (E.P. Study)\nThe procedure involves inserting a catheter – a narrow, flexible tube – attached to electricitymonitoring electrodes, into a blood vessel, often through a site in the groin or neck, and winding the catheter wire up into the heart. The journey from entry point to heart muscle is navigated by images created by a fluoroscope, an x-ray-like machine that provides continuous, “live” images of the catheter and heart muscle. Once the catheter reaches the heart, electrodes at its tip gather data and a variety of electrical measurements are made. These data pinpoint the location of the faulty electrical site. During this “electrical mapping,” the cardiac arrhythmia specialist, an electrophysiologist, may instigate, through pacing (the use of tiny electrical impulses), some of the very arrhythmias that are the crux of the problem. The events are safe, given the range of experts and resources close at hand and are necessary to ensure the precise location of the problematic tissue.\n\nOnce the damaged site or sites are confirmed, the specialist may administer different medications or electrical impulses to determine their ability to halt the arrhythmia and restore normal heart rhythm. Based on this data, as well as information garnered before the study, sometimes the specialist will proceed to place an implantable cardioverter device (ICD) or a pacemaker or will perform radiofrequency ablation. In any case, the information proves useful for diagnosis and treatment.\n\nThroughout the procedure, the patient is sedated but awake and remains still. Patients rarely report pain, more often describing what they feel as discomfort. Some watch the procedure on monitors and occasionally ask questions. Others sleep. The procedure usually takes about two hours. The patient remains still for four to six hours afterward to ensure the entry point incision begins to heal properly. Once mobile again, patients may feel stiff and achy from lying still for hours. \n\nI have several arythmia disorders that i was born with and have been through these tests litterally over 50 times in my life,and while it may sound scary and painful it isn't ,you will receive sedation and pain medicine.Plus the info they can learn from these procedures in some instances can be life saving.Now i'm not saying you may have something life threatning.it may very well be something as simple as anxiety related but if it is bothersome enough that it scares you as much as it seems to i think i would see one of these doctors just to be on the safe side.

You are refering to cardiac arrhythmias.  The heart beats too fast or too slowly with a consequence of diminished stroke volume or inadequate circulation of fully oxygenated blood.  This can produce dizziness, weakness and in worse cases fainting.\n\nThere are various causes.  Age or infections can cause wearing out of nerves that control the beating of the heart muscle.  Tiny clots in blood vessels can deprive a particular area of nerve and muscle tissues of oxygen and nutrients, likewise fatty deposits in the coronary arteries.\n\nThe beat which controls the heart begins in the SA node which causes the musculature of the auricles to contract while the nerve impulse travels to the AV node in the middle of the heart.  There it pauses briefly while the blood is pushed from the auricles into the ventricles.  When the AV node passes the impulse to the nerve fibers which energize the ventricles, these muscles contract sending returning venous blood to the lungs, and freshly oxygenated blood (from the lungs) to all the tissues of the body via the arteries.\n\nIf the SA node is irritated, it may fire too fast or too slowly.  The impulse arriving at the AV node could be delayed too long there.  That is called AV block.  If blockage is severe, the ventricles may fall out of sync with the rest of the heart.\n\nMuscle needs recovery time.  If impulses arrive too fast the muscle may contract weakly.\n\nWhen one node fails, usually undamaged nerve in an area nearby takes over.  This is called an ectopic node.  \n\nWhen things are working normally, your doctor can see so on the electrocardiogram, a recording of the electrical impulses produced by the nerves in the heart.  Same thing you see above patient's bed when he is connected to a cardiac monitor.\n\nThe line has certain parts called P,Q,R,S,T. The P wave is an initial small one, the impulse traveling through the auricles.  Then it flatlines for a fraction of a second as the impulse is delayed at the AV node.  The QRS, a sharp very noticeable spike represents the nerves firing in the ventricles.  This is followed by a broader T wave an these nerves recover in preparation for another firing.\n\nLots of different things can go wrong.  Much, but not all, can be determined from the EKG.  For example, the condition of the heart valves is not shown.  The doctor must take blood pressure readings, pulse, listen to the valve sounds.\n\nIf the aortic valve dows not close properly it can cause the heart to enlarge, the person has a very high systolic blood pressure (during beat), but a very low diastolic pressure (ventricles resting).\nMight be 200 over zero according to the nurse.\n\nSince our hearts are so vital, we should not take them for granted.  Don't eat too much fatty food.\nGet your exercise to keep up your circulation and reduce clotting.  Eat healthy foods that serve to maintain your nerves.  This requires vitamins and minerals.  Too little Calcium can cause problems.  Too much or too little potassium also causes trouble.\n\nThis is only a partial explanation of a big subject for a little place.\n\nGot to stop somewhere.

Go to a well qualified doctor.  My heart did that for years and was never cuaght on EKG.  Then one time I was able to get to the er when it was doing it.  I ended up having to get a cathader ablation done.  Were they go in your blood vessals with a fiber optic thing and zap some nerves in the heart.  it took two times but I have been fine ever since.

That could be a common problem of stress, or thyroid problems.See your doctor.

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!

Depends on what you mean by palpitations. If it is just an awareness of the regular beating of your heart, but the rhythm is regular (maybe fast), then it might just be anxiety. If it is a missed beat every now and again, it might be a premature ventricular beat, which is usually not dangerous, but you might need a 24 hour Holter monitor to determine how frequently it happens. Sometimes, cutting down on coffee might reduce the symptoms. Write to me if you need any more information.

It sounds to me like you suffer from anxiety attacks, which is very common.  It is usually an inherited condition.  I have it and so do members of my family.  Your best course of action is to STOP living in fear!  When I first had a panic/anxiety attack, I thought I was dying!  I went right to a doctor and told him what my symptoms were: sweaty palms, heart beating very fast, shortness of breath, a fear of dying right then and there when I had the attack (which, by the way, was on an uncrowded bus on a beautiful summer day with all the windows open, so it wasn't due to claustrophobia).  He put me on a very low dose of medication that stops the attacks before they start.  It helped me tremendously!  So much so, that after awhile, when the attack would start to creep up on me, instead of taking a pill, I would identify what it was and that I was NOT dying or having a heart attack, and I would talk myself out of it.  Now I have been "attack free" for 5 years!  But please get to a doctor and get checked out.  This is a VERY treatable and curable disorder.

Yes this could be from anxiety. The light headedness, and excess swallowing from nervousness, and the shortness of breath from possibly hyperventilating from too much worry about the situation. Id say mild panic attack but the chest pressure with light headedness could mean worse. Id get an ekg and " get it off your chest".

There are no nerves in your brain, so it is not your actual brain. I would talk to a doctor if this is seriously bothersome.  My first thought was mini stroke or aneurysm

If what you were wearing was a holter monitor, No!\nIn the 24 hours that you wear this, something must appear in the reading as abnormal. If nothing showed up as abnormal, and you're  still concerned, you should let your Cardiologist know that you are still uncomfortabe with the results.Obviously, no one could tell you that your palpitations are benign, in that there could be a few things going on. But, palpitations are very common in all of us. You can't relate these with 'major heart problems', as you ask. Major heart problems are in a different class. In the 24 hours that you wore this monitor, an event had to take place in this time. What are the chances of this, again, no one really knows.You can't expect even an educated guess here. What you're experiencing cannot go any further in a forum like this. The question is obtuse and requires your presense, your medical history, and your current symptoms.\n\nEssentially, you need to speak to your doc. Further, please don't ASK or ANSWER medical questions online. You will find, as you already have, that you'll get answers from laymen who think they know what they're talking about and being a layman yourself, you may mistakably take their advise. In this, you could be asking for big problems. I would be happy to answer questions you may have in giving you medical direction. Feel free to contact me. \n\nGrizz\n\nP.S. If you(audience) are not educated in this field, DO NOT answer medical questions in this forum. If you do, you are far from realizing that you may be putting people in danger. This is not the place for opinion, or personal experience regardless of your SINCERE intentions.

there might be a disorder in your autonomic nervous system. tell your doctor about it.ther may be a correctable cause for this symptom, let your doctor do the investigations.

You dont nessecarily need a pacemaker as drugs will help this ,but there are a number of things that cause irreg heart beats like caffiene nicotine overwork stress see a doctor to

Sounds like trouble with your central nervous system. Get checked by a doctor as soon as possible!

No it wont.  If you have palpitations you need to see a doctor...;

wow happens to me too from time to time......get checked for a heart arrhythmia

Sounds more like a panic attack than a physical ailment, and at 18, you're highly unlikely to have heart problems regardless of your family's history.\n\nNevertheless, a trip to the doctor wouldn't be a bad idea at all.  Electrocardiograms are quick and painless, and not all that expensive either.\n\nBut since you're also having stomach pains and migranes, I would bet money that it's stress or anxiety.

You have a symptom, only a doctor could tell you the correct diagnosis.\n\nThat could be a lot of things, like a stroke, stress, low pressure.
