Ravi Ranjan, M.D., Ph.D., is a cardiologist specializing in cardiac electrophysiology. His clinical interests include ablation of complex cardiac arrhythmias like atrial fibrillation, ventricular tachycardias and supra-ventricular tachycardias. He also has keen interest in cardiac device based therapy like cardiac resynchronization therapy, ICDs and pacemakers. He has been a faculty member at the Univ of Utah since 2010. He received his medical degree from Harvard Medical School, completed an internal medicine residency at Massachusetts General Hospital, Harvard Medical School, a cardiology fellowship at Johns Hopkins Hospital and a cardiac electrophysiology fellowship at Johns Hopkins Hospital. Dr. Ranjan has built a large clinical cardiology and electrophysiology practice in Utah.

Dr. Ranjan and Sara answer all of my questions. I do recommend them to others! :)

February 11, 2014

Very complete and informative.

December 19, 2013

very, very, good

November 19, 2013

I feel that Dr. Ranjan is exceptionally patient with my dislike for the meds I need to take.

September 20, 2013

Answering this section re: Dr. Ranjan. Once he came to see me (he was running late) it was a pleasant exchange and experience. He was personable and informative.

August 16, 2013

The care provider did not give me any explanation regarding why my heart rhythm is abnormal and seemed to assume that I could not understand a technical explanation.

June 08, 2013

best I have ever encountered in any health care facility

April 26, 2013

This was a follow up following a successful procedure that has improved my life very much. I had no real questions or concerns this time so did not need to make decisions or ask many question. Bottom line - I have had great confidence in my two cardiology specialists during the past several years and I believe that Dr. Ranjan's expertise had much to do with the successful resolution of my cardiac problem. I felt well cared for throughout the years long process. THANK YOU

April 23, 2013

I felt the care provider was interested in solving my concerns and seemed to provide a good plan to get more answers. He seemed easier to talk to this time.

April 08, 2013

thorough, informative, and pleasant in every way

April 03, 2013

I recived the very best of care

February 15, 2013

I had been referred to Dr. Ranjan by a friend. He made me feel very comfortable and confident in my decision to seek care at Univ. of Utah. Really liked his attention.

January 23, 2013

No problems

December 28, 2012

Still waiting for a decision on how to proceed. Wearing an eCardio monitor at present and expect contact from the Cardio Department any day now.

December 01, 2012

very knowledgeable

September 19, 2012

dr. and assistant were very good

June 13, 2012

I would absolutely recommend Dr. Ranjan to anyone!

May 15, 2012

Wasn't clear about who would take initiative in making decision to up medication dosage - me or the care team. Not knowing, I will call Shellie to see if she can get me the answer.

May 01, 2012

I feel safe and comfortable with everything we have experienced.

April 24, 2012

I liked that they worked to schedule the echo the day I was there to save me having to make an additional trip to Salt Lake as I live out of state.

April 03, 2012

Dr. Ranjan and his assistant were AWESOME. I never felt degraded in their presence. His down-to-earth explanation of the problem was done so without condescending attitude. I felt genuine care, concern and compassion in his care and approach to solving my medical issues.

Academic Bio

Ravi Ranjan, M.D., Ph.D., has appointments in both the Division of Cardiology and the Bioengineering Department at the University of Utah. His academic interests include the pathogenesis of cardiac arrhythmias like atrial fibrillation. His work involves using non-invasive imaging like MRI to quantify the structural changes in the atrial myocardium and study its clinical implications. He is also keenly interested in developing an imaging modality to confirm the delivery of ablation lesions in real-time in the myocardial tissue. This is to address one of the main reasons for arrhythmia recurrence after ablation being the lack of creation of permanent ablation lesions. His work spans electrophysiology from the single cell level to whole heart including mathematical modeling of cardiac electrophysiology. His research work is partly supported by extramural funding from the NIH.
