Sanjiv Narayan is Professor of Medicine, Director of the Stanford NIH T32 CHIP (Computational medicine in the Heart: Integrated Program), and is Co-Founder of the Stanford Arrhythmia Center. Narayan directs the Computational Arrhythmia Research Lab (CARL), that operates at the intersection of cardiovascular medicine, bioengineering, and data science. CARL pioneered computational mapping of 'chaotic' heart rhythm disturbances (arrhythmias), targeting mechanistic drivers for atrial and ventricular fibrillation (AF, VF) using machine learning and computational models. Dr. Narayan’s laboratory works closely with collaborators in London, elsewhere in Europe and North America. Dr. Narayan in 2022 received the Distinguished Scientist Award of the Heart Rhythm Society (2022), and has received prizes including "Top Doctor" (Castle Connolly). Our talented trainees have won numerous awards (an average of 2-3 prizes or grants every year since 2003).

Dr. Narayan was born in Aylesbury, Buckinghamshire, England, then his parents Prakash and Kamalini moved to Birmingham UK. He trained in medicine (MB, ChB 1987) and software engineering focused on neural networks (MSc, 1990). He gained membership (MRCP) and fellowship (FRCP) of the Royal College of Physicians of London. At the Lab of Neuroimaging of Dr. Arthur Toga, PhD at UCLA, he developed optical mapping and image processing software to study somatosensory cortex (Research MD, 1995). He trained in Internal medicine at Harvard/Mount Auburn Hospital under Dr. Charles Hatem, and Cardiology/EP (with computational research) at Washington University/Barnes hospital under Drs Michael Cain, Joseph Smith and Bruce Lindsay. Dr. Narayan is a devoted family man, and he and his wife Sujata Narayan (Family Practice, Stanford) have 3 children. Together, they enjoy music, history, politics, swimming, biking, skiing and travel.

CARL is grateful to the Laurie C. McGrath Foundation, and to the National Institutes of Health for continuous support since 2001 (HL70529, HL83359, HL103800, HL122384, HL149134 and SBIR grants). Our fellows have won funding by the Fulbright Foundation, NIH, American College of Cardiology, American Heart Association, Heart Rhythm Society, and British Heart Foundation. The lab co-invented intellectual property owned by University of California Regents and Stanford University, of which Focal Impulse and Rotor Mapping (FIRM) was licensed to a start-up founded by Dr. Narayan (Topera, acquired by Abbott Laboratories in 2014).

Excellent visit. I understand the plan that is laid out, and have more confidence in it as you have a holistic view... and are the only specialist at the moment who does. I feel more at ease and am confident that I am in good hands.

Dr. Narayan was excellent. He took the time to listen carefully and asked very good questions. He involved me through out. Although it wasn’t at all necessary, he apologized for taking a few notes. He is obviously very analytical, logical and very knowledgeable. He made me feel at ease. He explained everything so clearly. I liked how he made suggestions for how to move forward and included me in this process. I am so pleased that he is now my cardiac electrophysiologist.
Dr Narayan is the most competent Professor to treat Afib ..I just talked to him for few minutes last year before the procedure on the phone as the video didn’t work and today He remembered me as if I had seen yesterday. .Besides just before my procedure last year he got a medical emergency for himself so he referred me to dr Perino who did the procedure Dr Perino worked on my heart almost for 5 hours and came to see me showing me the very colorful pictures of my heart mapping just few hours later. He was very helpful and recomforting when I came home just3 days after the ablation on a long plane trip with severe heart problems du to the fatigue of the trip. Fortunately they didn’t last , but his team of nurses where calling almost everyday with checking and advices Overall it was a wonderful experience The best by far of my two previous ablations Thank you so much Drs Perrine et Narayan.

An excellent Dr.
All I can say about Dr. Narayan is that he is “THE BEST†!!!
Dr. Narayan is the best! He’s humbly worked hard and attentively on my behalf for 2 years, culminating in the collaboration with Dr. Anson Lee, who performed my surgery last Dec. After 8 years total of struggling with AFib symptoms, seeking treatment, and major insurance battles, my heart is calm and I’m profoundly grateful for the role Dr. Narayan has played. We’ve had fun in the midst of the struggles, which has actually helped my heart to heal.
Could not ask for a better M.D. to have in your court.
Very much like Dr. Narayan. Super Doctor and wonderful person. Would recommend him without hesitation.
Great doctor!
Dr Narayan is excellent and I am grateful for his help.

Good cardiologist. The communication on video is as good as it could have been if we met in office. Given the covid situation, the video is a preferred medium for me and probably for the doctor as well.

Willing to travel from Indiana just to see Dr Narayan for my heart needs
Dr. Narayan listened carefully and at length to my history and current concerns. He was both professional and empathetic.

I was made to feel I had been heard and that I was now in good hands moving forward.

Me and my husband feel Dr Narayan is very informative and personable Dr. He answers our questions in a way that we understand and gives us options.
very warm and engaging.Extremly helpful and professional
He is terrific - caring & informed - best cardiologist I've ever had.
Both Dr. Narayan and the Fellow, AJ, who initially spoke with me, were fabulous. What was most meaningful to me, and frankly a relief, is that not only are they clearly brilliant, but their humanity is firmly intact. I was talking to grounded, kind, down-to-earth human beings. Having dealt with dismissive, highly intellectual, harried cardiologists in the past 6 years, this was a most welcome relief that had a strongly positive impact on my overall sense of well-being. I felt heard, cared for, supported, like I am in good hands. Dr. N. and I ended up talking about the music they play during ablations and he promised to play Motown, my favorite. What I loved about this part of the exchange, which could have seemed frivolous, but wasn't at all to me, was the joyfulness of it. The human heart needs the brilliance and technical expertise that can easily be found in the world of cardiology, but the heart needs equal measures of kindness, joy, compassion and empathy to heal. To refer back to the awful welcome by the coordinators, it is mind-boggling that people like them are allowed anywhere near cardiac patients!!! More than anyone, really, we need TLC, kindness, love, compassion, and!! All of this is what heals the heart.
Dr. Narayan is a real gen! I am fortunate to have him as my doctor.
Always a pleasant visit.
My doctors are truly world-class. I am honored to have them work on my case. Their humility and intelligence is remarkable.
I am privileged to be a patient of this great physician.
Dr. Narayan is outstanding!

Dr. Narayan and staff were exceptional in care and thoughtfulness.
All good.
Dr. Narayan, always has a smile, makes you feel 100% listened to, as well as providers answers to all and any questions, or concerns about your treatment.

Excellent, I felt I was talking to my father like home.
Dr. Narayan is hands down the best doctor I've ever had and I've had many more than my share. That is why I travel from Chicago to see him. Stanford is very fortunate to have him.
Dr. Sanjiv Narayan and I have great discussions! It more a chat amongst colleagues than doctor-patient.
Dr. Narayan is by far the most knowledgeable - Kindest physician I have seen.
Wonderful care
Very helpful & informative explanation given to us by the provider for the treatment & medication prescribed for the problem & condition.
Wow! Dr. Narayan is one of several EPs that I have interviewed for my ablation. He & his staff are the ONLY ones who asked about my personal safety at home.
Good experience.
Way beyond excellent experience.
