Had my first implant of a backup pacemaker for long term Bradycardia which l had for around 15 years. Procedure went well and the physical healing is very good, but l still feel tired although l am pacing at 50 which is much better than the low 40's l was getting before. I had lots of symptomatic ectopic beats before being implanted and the idea was to get the heart rate up and then use beta blockers to control the ectopic beats which are still happening and actually seem a little worse since increasing the beta blocker dose. Who knows, perhaps it will all settle down in the end. I do feel tired at times, l expect that's normal though.
