I have gotten "skipped" beats in the past, and for the most part I never let them bother me.  When I started to get Tachycardia from my anxiety, I didn't notice them very much.  The last few days I have been getting them again.  When I had them before, they used to make me cough.  The ones I have been getting lately seem different.  Just feeling the skip in my chest and if I take my pulse I can feel the 'skip."  Is this something I should be worried about or do they change sometimes?  I haven't been on my ativan now for 4 days, have tapered off of that and that has caused some increase in anxiety.
