I am an 80 year old man. I had 3rd degree heart block and got a dual biotronic pace maker and AV node ablation on June 21 and June 22. I'm doing just fine. My EP DOC set my heart rate at 80....I guess I should have asked why it was set at 80. He told me after my first check he will put it down to 70 and eventually at 60. I didn't ask the reason...has anyone else had this.
