Sanjiv Narayan, MD, MBChB, MSc, FRCP, an American Heart Association volunteer, director of the electrophysiology research and atrial fibrillation program, and co-founder of the Stanford Arrhythmia Center at Stanford Medicine, sees AI at a major inflection point in cardiology, enabling cardiologists to become more efficient, gain more detailed insights into their patients' risk factors, better answers to clinical questions and help in navigating procedures. But, he said AI will not replace cardiologists.
