I had sustained vtach with syncope. After a bolus in ER of amiodarone, 36hrs of high dose IV dosages, I was then put on 400mg x2 day (for 800mg total) for 2 weeks, stepped to 400mg x1 day for 2 weeks, then 200mg x1 for 1 month. I since had a successful ablation where the VT focal spot was induced/isolated in EP lab and have been able to go off everything except a beta blocker now, 50mg x2 day of metropolo …

100 - 200mg of amio is not what doctors consider a “high” dose. There can be side effects even at lower doses though. When on any dose of amio my primary care provider had me do monthly liver panel bloodwork to catch any stress on my organs as early as possible. Most providers recommend an eye appointment before and then regularly after. Note that amio has long half life and can take weeks to clear from your system so if you do go on it if you have any issues must attend to or stop immediately since it will continue to get worse for potentially 2+ weeks after stopping. For me I am relatively young (40s) and knew I didn’t want to be on amio for a long term management of my vtach, which is why I opted for the meds only for short term and then ablation for long term solution.
What options were offered or discussed for you? Sometimes you have to specifically ask doctors… “what happens if I refuse? What other options could we consider?” Etc
