January 26, 2015

I appreciated Dr. Ranjan's professionalism and expertise, I did feel like the initial interview with the PA, followed a few minutes later by an identical interview by Dr. Ranjan, was redundant and showed there was either not communication between the two providers or the system of two interviews is just superfluous. I was disappointed that the information from both my prior visit to the UMC cardiology clinic and my previously dropped off information from a historical cardiology appointment, was not available to Dr. Ranjan prior to the appointment, and even at the appointment much of the information was not accessible. This did not make me feel like the appointment was part of a collaborative care system.

January 20, 2015

I feel I had adequate and more time with my physician and even the physician's assistant. Questions were answered (I usually go in with a list) in terms that I could readily understand. Medication information was provided and I have the utmost confidence in this team and would highly recommend the U of U Cardiovascular Department to others. My husband at one time was also a patient of the Cardiovascular Unit and we were very satisfied then as well.

January 12, 2015

Initially, I did not have an appointment with Dr. Ranjan, but after I had reported some residual chest discomfort, he found time to see me in the clinic after my device check appointment! Very impressed with the concern he showed for my concerns, and the thoroughness of ordering some additional imaging to ensure my device and lead were positioned properly. I felt much more at ease after, and really appreciate that Dr. Ranjan made time in his schedule to see me the same day.

December 18, 2014

I have been so impressed with this journey to my decision to have an ICD placed. Dr. Ranjan has been exceedingly patient (for over a year), allowing me to make an informed decision. He provided me with peer reviewed articles, presented my case in conference to gain other expert opinions, and shared with me those findings. I could see that Dr. Ranjan was relieved when I finally made the decision to receive the ICD, and at that point shared more strongly his opinion which made me feel even more confident about the decision. I cannot emphasize how much I appreciate his patience while I took the time I needed to make a decision that I realize now could potentially save my life some day. I was also very impressed with the PA, Chris. He was the first person who saw me, and really listened and let me talk without feeling rushed.

December 16, 2014

Would have been nice to determine statistics on outcomes with Dr. Ranjan procedures.

November 18, 2014

All good experiences

August 19, 2014


July 17, 2014

I was seen be Dr. Ranjan's assistant for the main part of the exam. He seemed genuinely interested in my issues and showed concern and understanding. Dr. Ranjan was trying to see if I was a candidate for a pacemaker, and it has been decided that I'm not.

June 21, 2014

This was my first experience visiting Dr. R. Ranjan's office and due to the heart situation was slightly anxious. Dr. Ranjan explained everything to my son and to me in terms that were easy to understand. He is very personable and I liked that he answered all my questions and was genuinely interested and asked several questions of me, as well. His Physician's Assistant was also very friendly and informative. I have utter confidence in Dr. Ranjan and his staff and would highly recommend him to others. He was sensitive to my questions and put me at ease regarding a situation that I was unfamiliar with.

June 07, 2014

Dr. Ranjan was able to explain the need for another 30 day heart monitor, and I agreed with his assessment. I hope it will help to find the problem.

April 22, 2014

They were very busy in clinic that day, yet I felt as if the doctor gave me the time I needed to understand him and that we were communicating well. It was a good experience.

April 18, 2014

Dr. Ranjan is super.

March 11, 2014

I am sure your clinic is a busy place, and you're trying to accommodate as many patients in one day as possible. That being said, appointments can seem rushed.

February 15, 2014

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

June 07, 2013


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.
