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

some close interactiom a sample is below:

Reactive hypoglycemia is a common symptom of both POTS and CFS, and occurs through a complex series of neural and hormonal interactions which are not yet fully understood.  Researchers have discovered that people with orthostatic hypotension (low standing blood pressure) often get a drop in blood pressure after eating carbohydrate rich foods.  This may be caused by a direct vasodilation effect (increase in internal size of blood vessels) of suddenly higher blood glucose levels.  The traditional definition of hypoglycemia is an abnormal lowering of blood sugar levels after the body overreacts to carbohydrates with excessive insulin production.  Researchers now believe that this lowering of blood sugar levels is not the only cause of symptoms.  Recent studies suggest glucose aggravated aberrations of the production levels of adrenaline, norepinephrine, serotonin, dopamine, and lactic acid may be associated with reactive hypoglycemia.  

     Most patients with POTS have difficulty sleeping, which may result from a number of factors, including abnormally high adrenaline levels caused by increased orthostatic stress (the stress of standing).  Central sleep apnea is a common problem for people with POTS, which in some cases may be due to damage to the medulla, which controls important cardiac and respiratory functions.  Central sleep apnea causes breathing to temporarily stop while sleeping.

Hi,
I get episodes of tachycardia beginning within 30 to 60 minutes of meals. The heart starts racing and sometimes goes upto 120 times per min. Several times I have had tests done but nothing abnormal was detected yet the problem continues. It was som consolation to realize that I am not the only one suffering from such symptoms and there are many like me. Do not really know what to do about it.

Hi,
I am a physician from turkey. I have got the same complaints for at leat 15 years. I am 36 years old and not overweight. I always fear to eat any think. But I used to eat very small amount of food. I get tachycardia and hypertension (especially diastolic HT)and I have to get rest for 1:30 hours. But I feel these kind of problem recurs after long period of fasting, I mean if I miss lunch time. And dinner is a nightmare for me. Now I had breakfast with only 2 slices of bread and cheese with 1 small couple of tea, I have increased HR winh knocking heart on my chest.

I always thought that it was just distension of my stomach and by the way of autonomic plexus just around the stomach makes sympathetic stimulation and makes heart to beat very fast and vigorous. I think this is true for me because I usually need to go toilet for cramping in my abdomen. This is the work of autonomic system. I have not found any solutin to these problem and I think there is no mechanical explanation as well. May be Some kind of B-blockers may help but do not take it by your self.

I will be happiest man on the earth if some one would find a reliable solution to these problem. If it occurs I will give you a dinner with unrestricted amount.

I'm also happy I found this forum. I've been searching the internet for a few months now for info about this and other things. I'm a 22 year old male and I had a catheter ablation in April 03' for SVT.

About 6-7 months after the ablation I started having some problems and this was one of the major things bugging me. I told myself at first that it was just my heart recovering from the ablation but I had a few panic attacks and I went to the ER one time. I never could understand why my heart would do this after eating (it ussually beats about 110-140 after a meal depending on what I'm doing at rest its 65-85. I've been freaking myself out lately thinking that I have an Abdominal Aortic Aneuryzm due to the catheter damaging my Aorta. I started freaking out about this because I could feel my heart beating in my stomach and when I felt my stomach I could feel my pulse strongly even about 2 inches left of my midline. I dont have insurance so I haven't been able to see a doctor in about a year.

I feel bad for all you guys but its kind of reassuring knowing that other people are having the same problem and maybe its not related to the ablation I had. What I've been doing lately is eating smaller meals with little to no sugar and only healthy fats in moderate to small amounts. Alcohol with food has been the worst for me so I've eliminated that. Its interesting to me that a couple of you have GERD. Thats something I'm going to check into. Good luck you guys.
