“Pocket Pill Adverse Reaction”

I have used the “pocket pill” protocol without side effects to deal with afib episodes that strike about every six weeks on average. However, when I recently used it, my heart rate and BP crashed. Couldn’t stand up. Wound up in the hospital overnight for observation. All fine the next day. Same symptoms, same protocol, hugely different outcome.

Anyone else have an experience like this? Here’s the protocol I followed successfully many times, except this one:

25 mg metropolol
Wait half hour and if persists, take 2 150 mg flecainide
If your Afib continues despite taking the metoprolol 25 mg and flecainide for breakthrough episodes, you can repeat the metoprolol again after one hour and continue monitoring. You can take an additional (3rd) metoprolol 25 mg again if needed.
