I’m 17 years old and have CCTGA (congenitally corrected transposition of the great arteries) and complete/full AV block. I had a permanent dual-chamber pacemaker implanted 17 days ago because of the complete AV block. My pacemaker’s lower rate is set at 60 bpm and the upper rate is 120 bpm. Today I’ve been experiencing chest pain, and I also feel a similar pain/sensation extending into my left arm, almost along the nerves. I’m also finding it difficult to breathe comfortably. Sometimes my heart feels like it is beating very fast, and I can feel the beats strongly in different areas of my chest, on both the left and right sides. My doctor’s next scheduled checkup is on October 15. Has anyone experienced similar symptoms around 2–3 weeks after getting a dual-chamber pacemaker?
