AI analysis of ECG data measured by smartwatch may help detect reduced heart pumping function

AI Summary

Researchers reported that AI analysis of smartwatch ECG readings may help detect left ventricular systolic dysfunction, a condition that reduces the heart's pumping ability. Preliminary results varied by smartwatch brand and recording, and were presented at the American Heart Association's Scientific Sessions in Chicago.

Artificial intelligence (AI) software tasked with evaluating heart signals (ECG data) measured by smartwatches may help identify a hidden and dangerous heart condition known as left ventricular systolic dysfunction (LVSD), although results varied between smartwatch brands and across ECG recordings, according to new, preliminary, independent late-breaking science presented today at the American Heart Association's Scientific Sessions 2026. The meeting takes place Nov. 6–9 in Chicago.
