Artificial intelligence enhanced electrocardiograms effectively identify heart failure

Artificial intelligence (AI) enhanced electrocardiograms are quicker and outperform current standard-of-care tests to identify patients presenting to emergency rooms with shortness of breath who have left ventricular systolic dysfunction (LVSD). The study published in Circulation: Arrhythmia and Electrophysiology, an American Heart Association journal, found that AI-enhanced ECG was better than standard blood tests such as blood levels of natriuretic peptides in identifying which patients have LVSD. Natriuretic peptides are elevated in the blood when heart failure is present. However, these biomarker levels are also affected by obesity, age, kidney disease, severe infection, high blood pressure in the vessels that bring blood to the lungs (pulmonary
