I'm on 100mg of metoprolol and 50 losartin with potassium. My PVCs aren't frequent but notice when I have them some feel like very uncomfortable in the chest and cause indigestion. Been to ER, had trays, blood work and ekg EP said that my EKGS haven't changed or gotten worst. Going next week to have a loop recorder placed under my skin so EP can see what I'm feeling. And yes I feel everything when the PVCs hit. I'm scared of these PVCs especially when they make my chest feel uncomfortable. I haven't been told about taking supplements such as magnesium. Anybody else's PVCs are uncomfortable?
