I just received a communication from a good friend of mine who is in persistent AF and is also over 70 and has recovered from COVID-19. She started daily meditation practice (TM) about a year ago and has recently added in the HearthMath practice for calming HR and has just sent me an ECG showing that she has managed to reduce her resting HR from 100 ish to 80 without the use of any drugs (she is very against them) other than anticoagulant and very occasional beta blocker as a PIP if she has sustained high HR following exercise.
I am so delighted for her but also clear demonstration to me of the helpfulness of these daily practices in the importance of managing stress and worry to help manage your HR and thereby your AF and general wellbeing.
Go well friends.
