Cardiac Arrhythmias :: Palpitations Due To Anxiety?

I'll get straight to the point. I have been suffering from Vestibular Neuritis for almost a year, to summarise it, its an inner ear problem which affects your balance and can take years for the brain to compensate for it.

It has multiple side effects, the most common and most problematic one being anxiety. At the start I had too many panic attacks, I couldn't even leave my room. However, by doing things like yoga, meditation etc. I managed to recover a LOT in terms of ANXIETY. Medication didn't help and as my anxiety got under control along with my brain compensating for the lack of balance, I started to feel better, but all symptoms were still there 24/7 to a lesser degree.

One month ago, I relapsed. I assure you, I did nothing different and have no idea why everything came back. As you can imagine my anxiety sky rocketed again. It took me about 2 weeks for the dizziness to calm down as brain compensated for it again. However my anxiety seemed to be there, I tried yoga etc. again (as it was so successful last time) but it did nothing. I have also noticed for the past 2-3 weeks, my bowels have been very irritated- without going into too much detail, I will just say that the frequency of my toilet visits per day shot up. I assumed (and still assume this was anxiety related) so I continued yoga etc. with not much improvement. I changed my diet to eat only bland, simple food...still not much luck.

My latest problem, and this is the one I need MOST help with. Three days ago, as I was trying to sleep, I started getting palpitations which really scared me- I have never had them before. NOTE: I had EKG, ECHO, Holter done 6 months ago and all was normal, so my heart was fine then and is fine now as I had another holter done last week - HOWEVER this time around it was clear that I had ectopic beats but the doctor said this was normal.. This has really made me feel anxious especially because I never had this symptom last year when my anxiety was at a peak.

Yesterday, the palpitations got really bad, I had to take a 4 hour ferry and then drive 4 hours. iI had a fairly greasy burger on the ferry and about 90 minutes later I started feeling ill and had palpitations again. This was the most scared I have been, I felt the urge to go to the toilet a lot and everytime I went, I felt like I was going to faint. My 4 hour drive later was scary too, I almost stopped at a B&B because I kept getting palpitations. The palpitations I had yesterday was different to the ones I've had for the last 10 days...instead of a 'thud' at the end, I had a sense of radiation warm sensation from my chest to my stomach which was really scary and moments of a feeling where you feel like youve lost consciousness for a split second before being 'shocked' into reality.

Has anyone experienced this? Do you think its anxiety related?- If yes, why has it started to happen all of a sudden?

Or do you think this is something to do with GERD? I seem to burping more and feel more 'wind' and also seem to want to go to the toilet more.

I also feel dizzy because I'm eating less because I get scared to eat any amount as the palpitations are triggered!
