My AF has been more or less under control since taking Flecainide and Diltiazem, and I am waiting to start Warfarin prior to having an ablation end May. My question is: I saw my chirooractor on Tuesday regarding my back/joint problems and because of the AF he said he would not pull me around but used acupuncture and ultrasound on my shoulders and back. I went into an irregular AF yesterday for about 2 hours and today I feel very washed out and slow. Does anyone think there is a connection? Thanks for any responses and advice.
