@jacqincalifornia Interesting info. I too have LBBB along with “mild AFIB”. PVCs during an elective surgery sent me to my first Cardiologist appt/tests that discovered my status. High CAC score, controlled BP and naturally good cholesterol (still take a statin daily). My iWatch 10 rarely reads ECG other than inconclusive and never know why. It has reported one or two AFIB episodes in last 18 months and does show summary reports of >3%-6% AFIB by the week in Apple Health app. Visit with Cardiologist and Electrophysiologist recently came to agreement to take me off of Apixiban. Also offered to insert a loop recorder to monitor AFIB full time if it would give me peace of mind. I declined as my symptoms and apparently events have been managed by lifestyle changes: weight loss, 0 Alcohol, 0Caffeine, Low Sugar and daily walks of 2+ miles. What I don’t know is when and how many PVCs I may be having? Perhaps I should reconsider declining the loop recorder?
