S.M. “Mark” Borganelli, MD, FACC


  • What is your position in the clinic? I’m the head of cardiac electrophysiology and the treatment of heart rhythm disorders. I’m also over the pacemaker and ICD clinic.
  • What are your responsibilities in this position? I am the only electrophysiologist for a large cardiology group and a large group of referring doctors in our city and also in the state. I specialize in the evaluation and treatment of heart rhythm disorders, basically arrhythmias. I also do a lot of devices where we put in pacemakers, defibrillators and heart failure devices. I’ve also started up a center, along with Dr. [L. Carr] McClain, to do what’s called device management and lead extraction.
  • How long have you been with the clinic? I have been with the clinic a year.
  • Where is your hometown? Born in Jackson, Miss., and raised in Greenville, Miss.
  • When you’re not at Hattiesburg Clinic, what do you like to do? I love golf; snow and water skiing, and I love football and Mixed Martial Arts.
  • What makes you proud to work for Hattiesburg Clinic? The ability to establish a much needed electrophysiology program in this area.
  • Tell me something your co-workers don’t know about you. They probably don’t know that I was one of the people who helped pioneer radiofrequency catheter ablation in the early days and wrote several papers on catheter ablation of heart arrhythmias. And I did the first pectoral implant of an ICD in the state of Florida.
