Electrocardiography

Electrocardiograms (ECG) are a primary cardiac diagnostic test that measures the electrical activity in heart to identify overall cardiac function, arrhythmias and areas of ischemia and infarct. Standard 12-lead ECG breaks the 3D structure of the heart into 12 zones, each showing the electrical activity in that specific area of the heart. This narrows down areas where there are issues with coronary artery disease or electrophysiology issues. Many ambulatory heart monitors and consumer-grade ECG monitors use fewer leads so are less specific as to cardiac conditions or location of abnormal heart rhythms, but can show an issue that requires further diagnostic testing or treatment.

AI correctly IDs ventricular arrhythmias in 88% of patients with sustained VT

New research suggests AI could offer physicians a new, state-of-the-art approach to sudden cardiac arrest risk management.

The proliferation of artificial intelligence (AI) in healthcare includes numerous algorithms for electrophysiology (EP). Jagmeet Singh, MD, Professor of Medicine, Harvard Medical School, and founding director of the Resynchronization and Advanced Cardiac Therapeutics Program and Mass General Hospital, spoke with Cardiovascular Business at Heart Rhythm 2023 to explain how AI is being used in EP. #HRS2023 #HRS #AI

AI gaining popularity in electrophysiology

There are now numerous AI algorithms for electrophysiology. Jagmeet Singh, MD, examined how this advanced technology is being applied.
