Atenolol for Irreg Heart Rhythm

I have been taking Atenolol for approx 10 yrs now for an irregular heart rhythm as well as General Anxiety Disorder. i also have MVP and the Atenolol has really worked quite well in keeping my symptoms in check.  I started on 25 mg of Atenolol and in Dec. 2008 my Dr. increased it to 50 mgs as I had a couple of episodes of tacchycardia. Since the increase in meds,  I have put on approx 15-20 lbs despite being active (recently increased to 30-40 mins of cardio/day).  I know the extra weight cannot be healthy (i'm 6'0, 260 lbs) but I cannot take the weight off.  Should I consider having my dr. cut me back to 25 mgs to see if the weight will come off?  i also have a family hx of diabetes and was told that i was "borderline Type II" at my last checkup.  Please help!

I don't know anything about Atenolol and I haven't looked it up, but if possible side-effects listed include weight gain, I think it worth your time to see what you doctor can recommend as a good change (lower dose, or alternative medication).    At 6' I think you should target getting more than 20 pounds off, I'd think you'll feel better and have less diabetes risk if you get down to about 200.  I feel the pain, I'm 6'5" and about 240 and would like to drop 20 pounds, but I just love sweets (and eating in general).

I am 64 year old man who is on medicine for HIGH BP, Diabetes and irrglar heart beat. I am taking Atenolol  25mg(OD),Ramipril 10mg(OD),Amlodipin 5mg(OD),ecospirin 75mg (OD),Telmisartan 40 mg(OD) for HIGH BP.
I am taking Metformin 500mg(BD), Glimpride 1mg (BD) for diabetes beside taking Ayurveda medicine.
I get -irregular heart beat every now and then which lasts for 24 hours.Doctor told me to take CARDANONE 100mg everyday but it gives so many side effects that i am not regular in taking it. My HEART BEAT GETS NORMAL after 24 hrs but come back after few days and again goes regular after 24 Hrs.WHAT SHOULD I DO TO HAVE NORMAL HEART BEAT as taking ATENOLOL in higher potency lowers my heart rate to 50 and below .
