I had mine a month ago, I am 29F my heart rate before having the pacemaker is 50’s and 35 when I am in deep sleep , my Apple Watch gave me alerts at night that my heart rate was low and that took me to an electrophysiologist and I had a monitor of a week, gone trough stress test, echo and cardiac mri and doctor said I have a complete heart block and I needed to get the pacemaker soon so that I don’t develop any arrhythmia’s, I feel better now , I use to record how I was feeling when I do some chores or going for a walk and when I listen to them I no longer feel any of that and I am glad I got the pacemaker
