I am a patient at Mayo with Afib. I see Dr AJ Deshmukh for electrophysiology cardiology and I also have a cardiologist who is kind of like a primary care provider in Cardiology, Dr John Giudicessi. An EP Card is only going to try to manage for example Afib procedurally. Like wise other issues such as pacer needs etc. Dr Guidicessi manages all aspects of your heart health including heart failure, and refers to Cardiology specialists as needed based on whatever the heart issues are. I love them both. Great patient relationships. Excellent experts.
