Hi, I was just diagnosed with sino atrial node dysfunction. Apparently there is no cure for the swings in my heart rate including the SVT's/Sinus tachycardia that I get often and the too low pulses I get more infrequently... and the very high to very low BP's that come with it. They say there is no cure except with Medications, and life style treatment...like I suffer from generalized anxiety disorder and occasional panic attacks...I have a lot of problems with mornings and sleeping with my pulse spiking. Anyone diagnosed with this and what was their course of treatment and outcomes. I was told ablasion was not an option since it is the node miss-firing. I am having trouble with beta blockers (see my post on Bystolic anyone?) I have been on Verapamil since 1996 for the bouts... and it continued not to work anymore. Help, I am afraid, suffering a lot and it seems there is no end. Anyone been through this? Thanks
