A consumer smartwatch ECG that flags LV systolic dysfunction across manufacturers. If WATCH-LV holds up, who should act on a positive watch alert — primary care, cardiology, or no one until there is a clear echo pathway?
Key result
Smartwatch AI-ECG for detecting left ventricular systolic dysfunction awaits results from the WATCH-LV trial.
