There are several antiarrhythmic drugs: amiodarone, propafenone, sotolol, flecainide, multaq, diltiazem, etc.

Amiodarone is the 'big hammer'. It can get one out of an intractable arrhythmia and keep on there. However, it is a toxic drug, hard on the kidneys and lungs especially. It loads your system with iodine in favour of calcium, magnesium, atc. You can be on moderate doses of amiodarone for months, but not years. Not unless it's the 'last resort', which is what it is known as in the field. So, refuse amiodarone once, get a second opinion, but it might be all you have left. It happens to some of us. I used amiodarone immediately after a failed first ablation and when the emergency internist consulted my EP. The good EP felt that I needed stability until he could see me for a second ablation. That second ablation is now behind me, and I am apparently doing very well. Haven't been on amiodarone since eight weeks after the first ablation.

Each of us responds uniquely to the same drug. Some can tolerate flecainide, some find it a horrible experience. Same with sotolol, etc. Life is like that...right?
