A good book for anxiety and panic attacks is "The Sky is Falling." I don't know the author, but I got it at the library or you might look online.
Your PVCS's are real and I know the dizziness very well. You get scared and your body starts pumping out adrenaline, and the situation worsens. I was agoraphobic for a time.
I'm not sure if your heart rate is going up with the anxiety, but a breathing technique I learned helps me when I get tachycardia. If you'd like to try it, it's as follows: Blow out all the air from your lungs through the mouth, breathe in to the count of 4 through your nose, hold your breath to the count of 7, breath out through your mouth to the count of 8. Keep your tongue pressed against the roof of your mouth. Try it 4 times and when you get used to that, you can do it 8 times.
Another one that helps me is 3 deep, slow breaths in thru the nose, out through the mouth. Follow your breath, as it comes in and goes all the way to the bottom of your lungs and back up and out again.
Any meditation or distraction you can do will help keep your mind off the anxiety and bring you back to normal. I picture myself on the beach, walking in the surf, feel the wind on my face, etc. and it really does help.
I was on Toprol XL and took it 1/2 in the a.m. and half at night as directed by a nurse, even tho it is extended release, that helped. Now I take Atenolol, which makes me less dizzy that Toprol did. My cardiologist said it doesn't pass the blood-brain barrier. I take up to 2 25 mg. tablets, in divided doses, usually 1/4's. This has worked for me for about 7 years. Now I'm having other issues, but some of this might work for you. Stopping smoking might help, as it raising your blood pressure and just plain isn't good for you. Good luck -- hope some of this helps.
Let me add to the commentary - 10/day wow--I sometimes have ten/minute and after all the tests I didn't meet the requirements for an ablation and I probably wouldn't have done it if I did. Have you taken your BP when you become dizzy to see if it is low? 10 PVC's /day shouldn't make you faint. You did self report anxiety as a problem. Have you discussed this further with your doctors? Panic/anxiety attacks are a possibility.
As far as Im concerned you dont even have a problem.. "10 pvc's a day" c-mom man theres people that get hundreds, thousands a day. My Dr. told me he gets them now and then. I had 2 nurses tell me they get them. Half the population get pvcs now and then, and half of that get them systematically meaning 24/7
Normally dr's look at treating 6,000 - 8,000 daily with meds unless they're other circumstances involved and treat with ablation >15% of your total daily heart beats or roughly >15,000 pvc's daily.
What did your dr tell you is the reason you're getting symptoms such as dizziness?
I've lived with syncope (fainting), dizziness etc and arrhythmia's since i was 9. I was told nothing was wrong - even being symptomatic and frequent pvc's (bigeminy, trigeminey) dr's didn't want to treat me with meds; just ignored them until I was 42.
In a normally structural heart, pvc's are normally benign and just have to be dealt with the best we can, finding what triggers you have and avoiding them. They don't have to bother your quality of life if you don't let them - I lived with roughly 50,000 daily for years and had an ablation and still have about 10,000 daily =) They really didn't bother me until the functioning of my heart was involved.
If it's any consolation, there's a woman that my cardiologist treats with 80,000 pvc's daily with no problems...she found a beta blocker that worked for her and has no structural problems.
The E.P Drs will not go near you with that amount of VE's. The risks of the proceedure far outweigh any small benefit you may glean from it and if I were you I would continue as you are and tolerate the tiny amount of ectopics you are getting.
