BioSmart® Watch ZW03 Sleep Aid Watch - Intelligently Initiates ECG and Heart Rate

This smartwatch that automatically performs ECGs during sleep represents a major advancement in continuous heart health monitoring. Unlike traditional devices that require manual activation, these smartwatches are equipped with advanced sensors that can detect heart rhythm irregularities—such as atrial fibrillation—while the user sleeps, without any interaction. This feature allows for early detection of potentially serious cardiac conditions that might otherwise go unnoticed during waking hours. The data collected overnight is typically synced with a companion app, providing a detailed report that can be shared with healthcare providers for further analysis. By combining passive monitoring with medical-grade insights, these smartwatches offer a powerful tool for individuals who need round-the-clock heart health tracking in a seamless, non-intrusive way.
