I have afib, was diagnosed about 3 years ago. Went through ablation about 2 years ago which seem to work beautifully until spring of 2025, when I started having bouts of rapid heart rate that would not stop for 5-6 hours, sending me to the ER a couple of times, once resulting in cardioversion. Since then afib has been managed by adding Flecaidine to to Metoprolol and Eliquis regime. So far so good, even though I do have some atrial flutter now and last 3 day at home monitor showed I was in atrial flutter for the entire time??? Going to repeat monitor in 2 months. Generally, I feel like my afib symptoms are controlled by med regime, having sleep apnea diagnosed and treated, and stopping all alcohol. My biggest complaint is that Metoprolol hampers my exercise routine and daily activities due to weakness and heaviness in my legs. When I asked my cardiologist (more than once) and describe my experience, he says that leg weakness and heaviness is not a common side effect of Metoprolol, but when I look it up that is the first thing that pops up. Can anyone add clarity to this? He wants to ultrasound my legs to look for circulation issues, I am ok with this but am very doubtful that he will find anything. I am in really good shape for a 73 year old, and exercise (walking, weights, core program) everyday.
