I've found that both the benzos (valium, xanex, ativan etc..) AND the SSRIs (Prozac, Zoloft,etc..) help with palpitations. I have been on Prozac for almost two months and have seen my ectopic beats (PVCs) reduce. At my worst, I had maybe 6 a day. Now I'm down to one every couple of days. Anxiety makes them worse so the meds help the anxiety etc.. However, when I started the Prozac, I had them every day for the first week. If you go on SSRI meds, give them time to work.
What kind of anxiety medication have you been prescribed, a benzodiazapine "valium, klonopin,ativan,xanax" or is it a Antidepressant?
