In 2000 I began to have an intermittent atrial fib for which a cardiologist put me on Toprol XL 50mg 1 x day. It worked for several years although during that time I gained some 70 lbs which I attributed to the fact that I retired and am not getting enough exercise. Now in the past few months I am having episodes of premature ventricular beats, premature atrial beats, supraventricular tachy, all kinds of garbage heart pattern and frequently feel lightheaded for days at a time and from time to time feel like I am going to faint. Energy level is zero...which I attributed to the weight gain. My chest feels thumpy a lot of the time and I've had the 24hr Holter (which proved the above patterns I mention). Now, a cardiologist wants me to have a 30 day event monitor and echo cardiogram. After reading the postings on this board, I'm thinking I need to talk to my doctor about Toprol side effects which it appears that I might be developing! Bless all of you for posting your problems! Perhaps together we can solve our medication problems!!
