supraventricular tachycardia
"I am a 28 year old healthy female. I was diagnosed with Supraventricular Tachycardia just recently and was put on Toprol XL 25 mg. I have only had a few minor attacks since being on this medication however I have side effects - Constantly exhausted and don't feel like myself and I have a heavy feeling in my chest which is extremely uncomfortable.  Side effects have not subsided much since I started the medication 5 weeks ago. The side effects are bad enough to where I'm tempted to stop taking it and take my chances with the SVT! My doctor is recommending ablation procedure in hopes of that solving my problem and get me off the medication."
