[|Human|] I am 45 yr male morbid obese intermittent atrial fibrillation w frequent PACs. Tonight my PACs are painful. I have had 2 MUGA scans (EF 61) 2 chem and 1 tmst. No indication of angina or blockage. Current daily meds 250 mg Atenolol (150 mg A.M. and 100 P.M.) HCTZ/Triamterene, Aspirin (325mg) pantoprozal sodium 40mg
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. PACs (premature atrial contractions) in atrial fibrillation (AF) are suggestive of poor rate control in AF. And you are taking only atenolol for rate control. So in my opinion, you should consult cardiologist and get done Holder monitoring (24 hours continuous recording of ECG). If rate of AF is high or frequency of PACs is high then you will need Radio Frequency Ablation (RFA). This will treat your problem permanently. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
