Kat, yes that's exactly how I feel. Funny thing -- when it happened I thought it was my aortic valve. I inherited a faulty one. Been getting more calcified as the years go by but it's doing fine. Completely symptomless.
Saw the cardiologist. My pacemaker is having to work "lots of the time". It's also having to trigger atrial beats sometimes. I asked him why my version of heart block came on so suddenly. He told me it can be sudden but it's not known how often it happens like that because there's nothing to see at autopsy.
Cheers, Joy
