I am in flecanaide and diltiazem and waiting for an ablation date. My question is I am getting several episodes of PAF every day around the same time. Between 2.30 and 5 pm. I get several episode that only last a couple of minutes each, I feel as though I am going to black out, everything goes black and I get a buzzing in my head. My hands can also go numb. My GP is very good at answeringg questions but I have gone to see him so many times recently I feel reluctant to bother him again. Has anyone else experienced this and is it the PAF or the medications. Thanks for any advice Cathy
