@shmerdloff I haven’t used the Kardia Mobile since getting the pacemaker, and I’m not sure if it would interfere or not. Microwaves used to be an issue, but no longer are. Would imagine your doctor would need to let you know. I’m still on Flecainide for the Afib, as a pacemaker doesn’t address that problem, just the bradycardia caused by sick sinus syndrome. Hope this information helps.
