For more than two decades, Sanjiv M. Narayan, MD, PhD, has been working in the medical field. With postdoctoral training in neurology, electrophysiology, and cardiology, Dr. Sanjiv M. Narayan has spent much of his career serving as a cardiologist and teaching cardiology topics at schools such as Stanford University and UC San Diego. Dr. Narayan is particularly interested in atrial fibrillation, a major health problem around the world.

According to a report from Global Market Insights, the atrial fibrillation market in the United States is the largest in the world. By 2025, the market is expected to expand at a compound annual growth rate of nearly 14 percent.

Experts expect this growth to occur steadily over the forecast period because of the adoption of modern healthcare infrastructure in the US along with an increasing number of new devices that address atrial fibrillation and the growing US geriatric population. Global Market Insights also noted that the global atrial fibrillation market will also increase for many of the same reasons. The global market is expected to surpass $12.5 billion by 2025.


Improving the Prediction of and Response to Sudden Cardiac Arrest

The co-founder and co-director of the Stanford Arrhythmia Center, cardiologist Sanjiv M. Narayan, MD, PhD, and his team strive to develop new treatments for heart rhythm disorders such as atrial fibrillation. Formerly a professor at the University of California, San Diego, Dr. Sanjiv Narayan studies topics that involve a number of cardiovascular conditions, including sudden cardiac arrest (SCA).

SCA is a leading worldwide killer. People who experience SCA out of a hospital setting survive less than 10 percent of the time. To improve that statistic, certain challenges must be overcome in prediction and response pathways.

A study conducted by Dr. Narayan and other investigators found that prediction could benefit greatly by streamlining the classification of SCA by personalized risk factors such as genetic expression variants, their functional changes, structural factors in the heart and other disease conditions, using machine learning to integrate multidisciplinary discovery.

Response systems can be addressed by outfitting community response stakeholders (first responders, hospitals, schools, etc.) with external defibrillators and other technology to facilitate resuscitation when an SCA event occurs.

How Much Does the Cost of AF Ablation Vary Across Sites?

Respected cardiologist and researcher Sanjiv M. Narayan, MD, PhD, is a professor of medicine at Stanford University and the founder and co-director of the Stanford Arrhythmia Center. A former professor of medicine at UC San Diego, Dr. Sanjiv Narayan continues research into cardiovascular medicine, including economic factors that affect the treatment of atrial fibrillation.

The benefits of cardiovascular treatment can be negatively impacted by major variations in the price of procedures from one facility to another. A research team including Dr. Narayan recently examined data from the Medicaid database and the MarketScan registry to examine the price differences in atrial fibrillation ablation.

They discovered that the median price variation between facilities was $25,100, but 5 percent of the institutions charged up to $57,800 more for AF ablation. While the median prices are lower than they have been in previous research, the potential for major differences in prices at specific facilities represents an opportunity for the institutions to examine their prices and generate more value for patients.

What You Need to Know About Atrial Fibrillation and Stroke Risk

As co-founder and co-director of the Stanford Arrhythmia Center, cardiologist Sanjiv M. Narayan, MD, Ph.D., works to develop world-class therapies for heart rhythm disorders like atrial fibrillation (Afib). Formerly a professor at the University of California, San Diego, Dr. Sanjiv Narayan’s most important achievements include the development of a new cardiac ablation treatment called Focal Impulse and Rotor Modulation (FIRM), which allows cardiac surgeons to eliminate disruptive heart tissue with greater precision and efficiency.

One of the main reasons cardiologists are concerned with finding a permanent treatment for Afib is that people with this type of arrhythmia are five times more likely to experience a stroke. Resulting from a blocked or burst blood vessel in the brain, a stroke can have effects ranging from severe, permanent damage to the brain to death. Other important facts to know about Afib and strokes include:

1. Each year, about 700,000 Americans have a stroke. Of these, about 15-20% are due to Afib.

2. Roughly 35% of people with Afib will experience a stroke over their lifetime.

3. Afib risk increases with age, doubling every decade after the age of 55.

4. Women account for 61% of stroke deaths in the US, and they are at higher risk of death from Afib than men.

About the 40th Annual Heart Rhythm Scientific Sessions

Heart Rhythm Scientific Sessions

A cardiologist and professor of cardiovascular medicine at Stanford University in California, Sanjiv M. Narayan, MD, PhD, is a prolific researcher in the area of atrial fibrillation. A former faculty member at UC San Diego, Dr. Sanjiv Narayan is a longtime member of the Heart Rhythm Society.

The Heart Rhythm Society will hold Heart Rhythm Scientific Sessions on May 8-11, 2019, at the Moscone Center in San Francisco. This will mark the organization’s 40th annual conference for scientific sessions.

The opening day of the conference will kick off with two featured symposia. The first will focus on new developments in atrial fibrillation (AF) screening, with talks given by experts in the field. After the lecture, attendees will have the opportunity to ask questions of the presenters in an interactive panel.

The second symposium will focus on the findings of the CABANA trial, a 2018 landmark trial comparing AF ablation to drug therapy. To learn more or register for the Heart Rhythm Scientific Sessions, visit

Stanford AI Outperforms Cardiologists in Arrhythmia Detection

Sanjiv M. Narayan, MD, PhD, and professor of cardiovascular medicine at Stanford University in California, concentrates his research on the use of bioengineering techniques to treat cardiac arrhythmias at the Computational Arrhythmia Research Laboratory. A former professor of medicine at UC San Diego, Sanjiv Narayan is co-director of the Stanford Arrhythmia Center.

Stanford’s long-time reputation as a focus for next-generation computational and artificial intelligence work applied to medicine continues. Stanford university’s recent work in this field includes using artificial intelligence to detect arrhythmias by members of the Stanford Machine Learning Group. The group created a deep learning algorithm that has shown greater success in identifying arrhythmias than a control group consisting of human cardiologists. The algorithm is able to diagnose more than a dozen subsets among heart rhythm disorders. In addition, it can work with data from more remote communities in which many residents lack access to cardiologists.

The model developed by the Machine Learning Group, in collaboration with the company iRhythm Technologies, diagnoses rhythm disorders based on single-lead electrocardiogram signals.

According to researchers, the particular excitement inherent in this project lies in the algorithm’s ability to provide speed and accuracy of diagnosis across so many arrhythmia types, an accomplishment that had not previously been possible.

2017 Article Identifies Rotating Waves during Atrial Fibrillation

Stanford University professor Dr. Sanjiv M. Narayan is an expert in atrial fibrillation (AF), a medical condition defined by an irregular and often accelerated heartbeat. One of Dr. Sanjiv Narayan’s recent studies on the topic appeared in the June 2017 issue of the Journal of Cardiovascular Electrophysiology.

Entitled “Two Independent Mapping Techniques Identify Rotational Activity Patterns at Sites of Local Termination during Persistent Atrial Fibrillation,” the study addressed uncertainties in the general medical understanding of AF that arise as the result of inconsistent mapping techniques. It accomplished this by comparing two independent AF mapping techniques that measured results in the same patients.

The first study of its kind to use more than one AF mapping method, it identified stable rotational activation at specific sites in the heart that drove AF for multiple cycles. Both mapping methods confirmed these results. Researchers developed a new computer program to chart their findings and subsequently released this program for free on the Internet.
