Hi everyone! I'm 66 and had a Biotronik bi-ventricular ICD pacemaker implanted on 11-3. I have non-ischemic severe heart failure and a left bundle branch block causing my ventricles to contract unevenly. I read on the Mayo Clinic site this pacemaker is programmed by a rep of the pacemaker manufacturer. I never saw one, and when I asked they said it had been programmed during the procedure. They discharged me the same day, and I was re-admitted through the emergency room an hour later because of severe dizziness and nausea. The next morning a rep from Biotronik came to my room and programmed my pacemaker 4 times until the cardiologist on call was satisfied. I can't help but think they discharged me hours after the procedure with incomplete or no programming. This is a very scary thing.
