New arrthymia and sotalol

I am 53.  I've had bypass surgery 10 years ago.  I had an MI when the grafted vein blocked back up 4 years later.  One year later I started to go into ventricular tachycardia too frequently they implanted a ICD.  After another year I had a day where I had VTac about 10-12 times in one day.  They loaded me with amiodarone and I have been on 200mg daily since.  A couple of weeks ago I had my first episode since.  Later I found it was atrial fibrillation.  I have also developed hyperthyroidism.  Last week my doctor took me off amiodarone and Coreg and started me on Sotalol.  I have health anxiety bad enough.  Does this sound like a smart treatment and how likely am I to start getting "shocked" again?

Sotalol is an antiarrythmic in the same class as amiodarone and is an appropirate second choice given the fact that you are intolerant to amiodarone.
However, another question you should ask is how are they treating your hyperthyroidism, because this can have serious health consequences including inducing more ventricular tachycardia. Amiodarone most commonly causes a fairly reversible form of hyperthyroidism but can also cause another form which is difficult to treat. Make sure you know which for you have.

My endocrinologist did not indicate which type of hyperthyroidism I have.  She said it was difficult to treat due to the amiodarone still in my system.  At that time she was unaware that the amiodarone had been removed.  Her initial treatment is methimazole 10mg 3x daily.
