Since receiving my pacemaker in the winter of 2019, and now being monitored electronically thru a Boston Scientific device, I was contacted by Bogomilov's office about a concern. During a round of tennis, they noticed an arrhythmia and recommended a heart cath, which I agreed to. After nothing was found, Bogomilov recommended that I upgrade to a defibrillator, which is much more restrictive. He never met with me personally about this issue. He had his nurse relay that information during a tele-visit, and wanted me to schedule the surgery. I then sought a second opinion from a highly respectable Electro Physiologist who looked at my results and determined that all I had was an elevated heart rate due to exercise. He said flat out, "You do not need a defibrillator." Do your research and make the best decision.
