I too have sss. I had a total heart bloc, level three . Drs immediately put in a pacemaker five years ago . also had bradycardia. Pacemaker was set at 60 heart beats for low limped along with this and meds clonidine patch metatopol and some luck this spring after a wellness dr visit I got curious and studied up on my situation. Found out there are triggers that can set afib off. I have changed my lifestyle and diet to avoid these. Last one was alcohol. Now avoid this. Used to have arrhythmia late at night. Since I got hold of my lifestyle and no alcohol I have good Rhythm, with good bp.
