I'm new to this site and am glad to see posts relating to AFib and other people's experiences. I have been diagnosed with sick sinus node and have a pacemaker and take flecainide for AFib along with Metoprolol. I also have SVT. Lately I have been having crazy arrhythmias that seem to be worse when I am really tired. The readings on my pacemaker don't show these as AFib events. I have been told they may be PVCs. And weirdly enough, my pulse is read in the 30s even though my pacemaker is set to 60 and shows normal in the data when checked. They are so bothersome and getting worse but I don't know what is causing it. Has anyone else experienced this and if so, is there anything I can do to ease them?
