My first EP, 1.5 years ago, diagnosed me with a complete A/V block and recommended a pacemaker. I have researched complete A/V block and it is my understanding that means no electrical signals pass from the atria to the ventricles. If I had a full-time 3rd degree heart block, prior to the pacemaker, how did I survive? I began seeing a new EP several months ago- he diagnosed me with 2nd degree heart, Mobitz type 2. Does that mean I don't have complete heart or A/V block?
