Last week gave the lowest level of arrhythmias for ages - about 37 hours for the week. Had quite a lot of episodes - at least 1 every day and at least 11 in all. Not sure why the total so low though less exercise recently so less tired, emotional changes also. I tool 150 mg of flecainide as a "pill in pocket" fairly early on in each episode which appears to have helped clear them up.
Arrhythmia triggers were interesting. Started arrhythmias:
immediately on lying down in bed
while asleep, it woke me up
a few moments after waking
Thats all pretty vagal.
