Health Monitoring Smartwatches: Beyond Basic Heart Rate
Advanced heart rate monitor watches now use PPG sensors and ECG technology to detect atrial fibrillation. The EZON R7 provides FDA-cleared ECG readings and blood pressure monitor watch capabilities through pulse arrival time analysis.
Blood oxygen (SpO2) tracking has become critical for sleep apnea detection. Devices like Garmin Venu 3 measure overnight SpO2 levels via their sleep tracking device, correlating data with respiratory rates.
For extreme sports enthusiasts, rugged smartwatches like Garmin Instinct 2 Solar combine MIL-STD-810H durability with ABC sensors (altimeter, barometer, compass). Their 28-day battery life outperforms most consumer-grade models.
Medical researchers emphasize the importance of cross-referencing calories burned calculator data with heart zone training. A 2024 Johns Hopkins study found that users who combined these metrics improved metabolic health 23% faster.
