Kind: research · Impact: medium

## In brief

- A Korean study found difficulties with smartwatch detection of left ventricular systolic dysfunction (LVSD) in its current state.
- The study used an AI-ECG approach to assess smartwatch-based detection of reduced LVEF.
- The findings temper enthusiasm for smartwatch detection of LVSD, as reported by MedPage Today.

## Why it matters

Smartwatch tools that flag reduced ejection fraction could change how heart failure is screened, so readers should know that current accuracy is still questioned.
