I'm 39 and a year ago I had a couple of episodes of SVT. After investigation by a cardiologist I was diagnosed with Atrial Flutters. I take 5mg Bisoprolol every day. I'm a busy working Mum of two who used to be able to run around and complete all my daily tasks with time to spare. Now I feel like a fraction of my former self. I'm tired all the time and lack energy. I get frequent pains in my legs. I also get frequent headaches. I drink as much water as I possibly can during the day as someone told me that Bisoprolol can make you feel dehydrated. Will this ever get any better?
