I can’t really comment on the life expectancy question, but I can share my own experience. I was first diagnosed with AFib at 59. I didn’t know what it was at the time—just went to the ER with shortness of breath and extreme fatigue. That day I learned I had AFib, a left bundle branch block, and an ejection fraction of only 25%. I spent five days in the hospital getting started on Tikosyn, along with Metoprolol, Atorvastatin, Xarelto, Spironolactone, and Diovan. Up until then, I hadn’t been on any medications at all. Fast forward 8 years and one ablation later, my ejection fraction has improved to 60%. I was able to stop Tikosyn after 90 days, though I still take other meds. Along the way, I also got my sleep apnea treated, cut alcohol down to no more than one drink a week, lost weight, and brought my blood pressure into the 110/70 range most days. As an aside, my father—who also has left bundle branch block—just celebrated his 96th birthday. He had a pacemaker installed at age 94.
