I have had a ICD/Pacemaker since 2006 (on my third one). I have had VTACH, PVCs, PACs, AFIB, VFIB during those years.
Back in 2016 the wires in my pacemaker were developing serious impedience which was affecting battery life. They decided to try turning off the pacing. Within a week on one day I had 5 shocks (first time ever) within 24 hours. I was put on Amiodarone drip in hospital and pills afterward. Amiodarone is a great medication and worked for me bringing my heart back into rympthm.
However like your dad I had read about Amiodarone side affects and toxicity to body. With discussions with my EP he agreed to ween me off of it slowly over a 6 month period. I still have to have yearly eye exams to check if the amiodarone caused any damage to eyes which is one of the side affects.
The dose I was on was high and I have read on MCC many on Amiodarone on much lower dosage for long periods of time.
Since we are not medical professionals ask your dad or you to talk to your cardiologist about the side affects of amiodarone versus the benefits of it for your dad. Your doctors know the seriousness of your dads VTACH and the presciption dosage level.
If you and your dad are in doubt you can always get a second opinion from outstanding medical facilities like Mayo, Cleveland Clinic, John Hopkins and most of the time it can be done by submitting medical information to the second opinion facility. I did this with UFHPTI to get second opinion from diagnosis from Mayo and wanted second opinion.
Good luck but please talk to his doctors about the risks and benefits of amiodarone and if still in doubt suggest you consider a second opinion on treatment of your dad's VTACH.

It appears, from me and one other member, that amiodorone may cause eye scars, which have to be removed by laser.
