Tachycardia after eating a heavy meal?

Please explain why I sometimes get tachycardia within a 1/2 after eating a heavy meal?  The heavy meal usually causes bloating and indigestion, then tachy.  This doesn't happen all of the time, just when the meal is particularly rich with carbohydrates and/or fat.

Thanks

What a relief to find all of you and read about your experiences!  So sorry about your suffering though.  I too have had incidences of a racing heart (usually about 100bpm) about 30 minutes after eating a meal.  I'm a 35 year old female, 115 pounds, exercise regularly and generally am in good health (other than dealing with low blood sugar).  My heart has been checked as well and comes out clean as does my bloodwork.  About a year ago, I suffered with panic attacks (daily) with that lasting about a month and a half.  [I have to credit the Lord with healing me from those.  That healing came as a result of asking Him to take them away (which I had asked a number of times before) so that I could get on a plane to fly across the US (no way THAT could happen with panic attacks!).  That time He said yes and I have had no attack that day or any day since - praise the Lord!]  Anyways, during that time, I would get the pounding heart after eating a meal that completely filled me up which would lead to a panic attack.  So, like many of you, I ate very carefully.  But recently, I started having the pounding/racing heart (but no panic attack) again after eating - not very often - the first occurrence happening after eating just a pnut butter sandwich.  I thought something was wrong with the pnut butter!  I called the doctor and he said if it doesn't subside to go to the ER (it subsided withing an hour or so).  Like many of you, drinking a lot of water gives me relief too.  It happened again tonite after eating a plate of chicken and noodles and vegies and then 2 Oreos.  This time I got online to investigate and found you guys.  Sorry I don't have any advice to offer right now but I plan to investigate further and will let you know if I learn anything useful.  I wish there was some survey we could all participate in to find out if there was some common thread between us.  Thanks to you all for taking the time to share - take care and God bless.

Hello!
I have also experienced an increase in my heart rate after eating.  Sometimes it will happen when I just sitting and watching TV.  It also happens when I lay down to go to sleep or just walk up the stairs in my house.  My heart will race and it feels like I have just ran a marathon!  I've had several EKG's, worn a halter monitor, had an echocardiogram and blood work to check my thyroid.  The doctors can never find anything wrong.  They always say that I'm perfectly healthy...which I guess is good, but it's still very frustrating not knowing why it's happening.

The feeling when my heart is racing is very uncomfortable.  It makes me feel very anxious.  I'm 39 years old and have been dealing with it for over 10 years.  Anxiety can be a trigger as well.  Sometimes relaxation techniques such as slower breathing can help, but it's hard to do when your heart is racing.  Also, believe it or not, drinking lots of water can help too.  I'm not sure why, but it does (sometimes).

It is a great comfort to know that there are other people out there who are dealing with the same thing.  I thought I was the only one.

Wow this is amazing to read all these stories that are the same as mine over the years.   It is reassuring to know we are not alone even though it often feels like  it.   I also have a racing heart after rating and have has for years.  I always thought everyone had that.  I now regulate how much I eat as well.   I have also learned to bear down and bend forward a little to make my heart slow down.   If I press down near my stomach it does help tremendously.  I agree that it is GI and vagus nerve related.  My heart also races everytime I go to sleep.   I put up with it for years thinking it was anxiety until a doctor found that my heart does have signals that are off as recorded on an EKG holter monitor.  This has never shown up again however.     Every doctor I've ever talked to seems like they have never heard of these symptoms before.   I tell them about waking up every night with my heart racing and about the eating issue and they just stare at me not knowing what it is.  
I have been on a beta blocker now for 15 years.  
I've mostly taken Atenelol.  I've also tried Bystolic which made me feel nervous and light headed.
I now take propranalol 60 mg.  It doesn't let my heart race but it makes me really tired.  My heart tries to race and it does pound hard after every meal but instead of 120 bpm it is around 84.  That isn't too high but it's a very hard beat that makes me feel nervous for no reason.  I can never wait for it to be done.   My stomach also blows way up after I eat and that makes my heart go fast too.  It's crazy!
Thanks everyone for sharing your experience.  I'm 46 and have had this since I was young!   People wrote me off with anxiety but I know better.   I've always thought I have a hiatal hernia and GERD ao it's interesting to see the connections on here.

I have been experiencing the tach after I eat for 4 years too. I thought it had to do with smoking. I quit 7 mos ago and I still get it after heavy meals. 120 bpm is standard. Its actually happening right now lol. What makes it go away in 5 mins fo me is throwing up. I've only done it maybe 30 times in 4 years because it can't be good 4 u. To throw up all the time ..but it works. I just try to eat lighter and it doesn't happen that often. It blows my mind that the medical pros haven't figured out this one yet.

I have this problem after a big meal, too. But I know I am Gluten intolerant from a Great Smokies Food allergy panel. I also get a racing heart in the morning, in the middle of the night or before bedtime and dread going to bed. I'm talking full tilt for 5-10 minutes at over 140 bpm. But I have found a few things that help  1) beta blockers before meals, 2) 'Cardio Well' herbs from Get Well International in San Jose area 2) Restricting carbohydrates of all kinds 3) a tranquilizer at dinner 4) the book called 'Potatoes, not Prozac' which explains the brain connection to insomia. Unstable insulin response - way up then way down can be detected with blood strips. And I don't care what they say in the media - I use L-Trypophane 500 mg at night and sleep much better. My med tests all came back normal but I'm still looking. Good luck to you all.

In October 04 I noticed about 20 minutes after I ate my heart felt funny, like it was miss beating. I went to my cardiologist and received a 24hr monitor. They lost the data on me. This went away. Now after 2 months its happening again. My wife (a nurse) listened to my chest during this event today and said my heart beat was normal but seemed to speed up a little then go back down. This stops immediatly when I stand-up. After about an hour passes the events stop. Whats this all about? I also forgot to say I have had benign PVC's for about 6 years.

My anxiety level just dropped through the floor now that I know Im not the only person on the planet with this condition. I am a firm believer in chiropractic care, my chiropractor has been helping me control this condition for about 3 months since it has surfaced. It is mainly caused by the agitation of the vegal nerve, accompanied by overeating and poor diet. Adjustments of the spine about 95% of the time completely cure the problem for a few days to a few weeks, which has helped me get passed the "Im having a heart attack" anxiety that really can make it worse. I too went to medical doctors and ran the tests only to be told I was in pefect health, and that my problem was a mystery. The best way to control this is diet, drink lots of water, and get chiropractic care-its the only way to take care of your nervous system. At least this works for me.

I have experienced irregular heartbeat after eating for the past 4 years or so.  The problem comes and goes, sometimes not bothering me for several months.  After eating, sometimes I will get what I believe is a complete cramp of my stomach and I am not able to even walk withhout assistance.  I can not perform even the slightest task (slicing a piece if cheese) without extreme discompfort.  At that time my heartbeat may or may not be affected.  If affected, the heartbeat is very irregular, missing beats as well as adding beats, sometimes dropping to as low as 30 beats/min.  I have had all the tests, blood, heart, neurogical, mental and so on with no problems in any area (except possibally the mental area, as a few close friends would say). Nothing shows.  I am not on any meds.  A few things I have found out.  Do not eat grapes or raisens or any thing made from them.  Certain fish  or fish products also set it off.  Eating pasta, bread, rolls, doughnuts, pastry, toast or anything like that in the morning is a never never do!  I eat protein in the morning, snack lightly through the day and a light meal of anything I want in the evening.  I have been in emergency 9 times in the past 4 years with nothing found.  I have had irregular heartbeat for 30 years without any problems caused by it.  I am, as I understand, one of many people who can feel their every heart beat and irregular heartbeat (arythmia) runs in my family.

Hey...

   It is very comforting to know that I am not the only one experiencing symptoms of increased heart rate after eating (especially foods such as pizza, chocolate, garlic, or foods high in oil). I am only 18 yrs old!!!!! and I am afraid of developing more serious problems of the heart as I grow older. My doctor does not know how to diagnosis these symptoms therefore I plan on seeing a specialist. Any words of advice are appreciated!!

What I meant to say actually that being sufferer yourself, you seem to have a  very thorough understanding as to what those who suffer from this is going through.

The sites you posted have provided some insight as to what might actually be the cause of some these distressing symptoms, though a true diagnosis is often hard to make, sometimes it is just a judgement call based on symptoms rather than any specific test.

Take care.
