Atrioventricular block is a common sequela of myocarditis, especially when symptoms such as panic and chest tightness are present, and is an absolute indication for the installation of a permanent pacemaker, which is recommended. Like many patients, you are understandably apprehensive, but the installation of a pacemaker will significantly improve your quality of life by providing relief from your symptoms. You are too concerned about the pacemaker itself, but not about your condition and quality of life. In fact, pacemaker surgery is very mature nowadays, and pacemakers are not replaced in 6 years. Most pacemakers last 8-10 years, and a few large battery pacemakers last 13-15 years, but at present the pacemaker manufacturer only guarantees them for 6 years. If your condition is not too serious, you can continue to treat your heart muscle to see if your heart rhythm can return to normal, and if not, it is not too late to consider installing a pacemaker.
