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.

New research underway on credit card-sized heart monitor that synthesizes 12-lead ECGs
The portable device uses HeartBeam's patented 3D vectorelectrocardiography (3D VECG) technology to capture signals from three different projections and deliver a synthetic 12-lead ECG.
AI helps cardiologists deliver personalized healthcare—but there is still plenty of work to do
A new scientific statement from the American Heart Association explores the many ways AI and machine learning are being used to improve care for heart patients.
AI could be a game-changer for TAVR, but cardiologists remain ‘irreplaceable’
The rise of TAVR as a go-to treatment option for many AS patients has been one of the biggest stories in cardiology for several years now. How will advanced AI models impact this trend going forward?
TAVR after mitral valve replacement linked to positive outcomes, but heart teams must plan ahead
Researchers in India performed TAVR on two relatively young patients with a preexisting mechanical mitral valve, sharing their experience in a new case report. The group highlighted the importance of planning ahead.
AI models for predicting heart failure still far from perfect
Advanced AI models can evaluate a patient's heart failure risk using 12-lead ECG data—but there is still some room for improvement.
