December 07, 2016

Dr. Ranjan has seemed an excellent and attentive physician in every respect.

December 02, 2016

I have recommended two of my friends to see this doctor already.

September 30, 2016

Both Kira Johnson and Dr. Ranjan were caring and attentive. The discussion and instructions were very understandable and clear; they were both very professional and made me feel both confident in their assessment and comfortable with the conclusions.

August 21, 2016

I have already told friends and family about you. I'm very confident I am getting the best treatment and consideration.

August 09, 2016

excellent performance

July 16, 2016

Doctor did an excellent job. Nursing staff left a little to be desired in procedures and knowledge of my medications.

June 18, 2016

As is the case often times, an Assistant usually consults first with me and then I see Dr. Ranjan. He does spend adequate time with me and explains situations to me in terms that I understand. I have the utmost confidence in Dr. Ranjan and would and have highly recommended him to others in his need.

June 14, 2016

Both the Doctor and PA were extremely good in all aspects.

June 10, 2016

Dr. Ranjan was very friendly and professional.

June 10, 2016

Doctor Ranjan thank you. I met you for the first time and have all the confidence that you can help me.

June 10, 2016

Dr Ranjan and his staff were awesome! I felt that I was under the best care available. Dr Ranjan's bedside manner was the best I've experienced! I appreciated his genuine care towards me and my condition.

June 09, 2016

Questions that I have had since having the procedure done were answered in a way that made sense and that I was able to understand. I am very satisfied with the care that was provided when I had the procedure done and the followups afterward. I am so grateful.

May 27, 2016

Dr. Ranjan listened to my concerns and was very helpful in explaining a medical procedure to me. I feel very happy about choosing Dr. Ranjan for my cardiologist and will be continuing my heart care with him.

May 26, 2016

The PA even drew pictures for me to help me understand exactly what was going on in my body. Two thumbs up for her.

April 15, 2016

I have recommended you often to many friends.

March 28, 2016

It is clear that my provider wants me to cure my condition rather than treat it with medication. I'm not ready to sign up for surgery, my provider has NEVER made me feel bad about my choice. The Physician and PA were both supportive and clear about my options and long term success of medication vs cure with surgery.

February 18, 2016

I usually don't fill out surveys, but i felt obliged to fill this one out because everyone was so good. very good experience, excellent staff.

February 12, 2016

Dr. Ranjan is very caring and also very competent.

December 04, 2015

I have not felt like Dr Ranjan took time to make me feel like he cared about my problem. I felt like he just wanted to move onto the next person. Also, I do not feel like test results are explained to me in a way that satisfies me. Maybe he thinks I wouldn't be able to understand, but I am an RN with a BA in school nursing. I could understand.

November 10, 2015

Dr. Ranjan and Laura the N.P. have been exceptional. A month before my scheduled appointment, I called with a concern about some burning pain around my device and Laura saw me in clinic that day, just to take a photo so Dr. Ranjan could see the redness. I was concerned that my device had "migrated" down and outward and so was concerned that the lead placement could be compromised, but Dr. Ranjan alleviated my concerns and encouraged me to keep exercising like I do. I feel like I am not a "typical" ICD patient given my extremely active lifestyle, and I always feel like Dr. Ranjan and his team encourage me to continue doing the activities that bring me happiness like cycling, running, and skiing. The great thing is now I have a "back-up plan" should my unfortunate genetic make up decide to get the best of me. Thank you Dr. Ranjan and team!

October 27, 2015

spent more time waiting to see someone than the actual appointment took.

October 02, 2015

Doctor is very willing to listen to my concerns and work on a plan to solve issues in a professional way.

September 05, 2015

excellent, very professional care

August 04, 2015

I routinely refer friends/family to UofU.

July 17, 2015

took the time necessary to listen to my story and told me what his thoughts were. both Dr. Ranjan and the PA were easy to converse with.

July 10, 2015

Excellent, as usual.

April 10, 2015

I have been so pleased with Dr. Ranjan throughout my entire journey that started in the fall of 2013. It was not easy to make the decision to live with an ICD for the rest of my life, but now I am so happy that I took action to potentially safe my life some day if my "unlucky gene" decides to manifest as a fatal arrythmia.

March 15, 2015

Didn't stay long but I think we discussed what needed to be discussed. I expect the follow-up to be longer when we go over tests.

February 13, 2015

I am so pleased to have Dr. Ranjan directing my care. I have total confidence in his expertise as a doctor and appreciate his concern for my health needs.

February 12, 2015

I had a great experience at the CV center. They were efficient and very thorough in their evaluation. they provided great information to me about the problem. I would recommend them to anyone with a cardiac problem.

February 05, 2015

The Doctor, PA were both extremely good. The male nurse brought the answers down.

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., is tenured Associate Professor of Medicine and 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.
