palpitation after food

i am 55years old , I am on eltoxin 100 mg daily because i had thyrodeyctom 15 years back   T4,TSH normal,I got a history of ?syncope or ?convulsion during sleep  repeated 2 times in 7 months apart ,I am not diabetic my blood pressure normal my weight is 83kg and hight 181 cm I have LBBB , echo showed mild LFV , ECG no sings of any type of malignent arrythmia, or heart block,coronary cathetrization normal,24 hr holter monitor showed 1554 PVCs, very few bigemeni, 2 only  trigemeni,EPstudy negative , vedio EEG during sleep showed some slowing over left temporal lobe , no epileptical form discharg, epilepsy MRI brain showed mild degeneration changes over left temporal lobe , Doctors kept me on Tegretot 200mg am, 400mg pm, plus concor (b-blocker) 2.5 mg am ,but I still have palpitation for 30-45 minit after each meal ,is there any posibillity of intermittent heart block (AV block) stimulated by stomach dilitation ,or carotide massage dueing sleep ,and what can I do? thank you

The question about palpitations after food is common and probably easy to answer. The rest of your cardiac history is not and should preferrably be answered by an expert.

How do you define "palpitation"? Like a rapid regular heart rhythm, a slow, hard but still regular heart rhythm or a rapid, irregular heart rhythm?

When eating, your cardiac minute volume must increase by 40-50% compared to during rest. There's only two ways to do that, either increase heart contractility (harder beats) or increase heart rate (faster beats). Most often, a combination is normal, but sometimes you just get one of them. And this is all a stress factor to the heart, possibly causing more PVCs or PACs or another form of cardiac arrhythmia.

By "LFV" do you mean LVF (left ventricular failure)? Do your cardiologist have any theories on why this is so? The LBBB is almost always indicating some kind of heart disease.

It's hard for me to say if you have an AV block. If you have a more serious AV block, your resting EKG would usually at least show a first degree AV block. I assume it doesn't. That said, 2nd degree type 1 AV block is common during sleep even in healthy people (happens in about 1/4 of us).

Ask your cardiologist why you have the LBBB and LVF(?). That will probably be of help.

I have many palps after I eat food...especially msg filled foods or foods high in cholesterol. They seem to fade away as time goes on after the meal..nothing serious I suspect. I know when I try and cut down meals during the day if the palps are increasing or worse, the better the results are for the following meals. I tracked in foods that helped alot in decreasing palps in my diet, and found that a light salad (greens, green/red/orange pepper/ onion, broccoli, and a light dressing) along with a tuna or turkey sandwich led to very few palps afterwards. But as a av block or something more along those lines I don't know, you probably would want to talk with your cardiologist about that if it continues to trouble you. Good luck!

thank you for answering me , I have mild LVH ,it was typing mistake , my cardiologist said that could be due to degenerative agent ,also LBBB,my question do you think that cnovulsion I got during sleep is primary nuctornal sizure , or due to cadiac arrythmia especially AV block ,thank yo
