Your heart doesn’t take days off—so why should your health tracking? With cardiovascular disease claiming over 659,000 American lives annually (CDC), monitoring heart health is no longer optional. Modern fitness trackers now pack hospital-grade tech like *ECG (electrocardiogram) and SpO2 (blood oxygen monitoring), empowering users to detect irregularities early. But with so many options, which devices deliver accurate, actionable insights? We’ve tested and compared the top fitness trackers for heart health in 2024, so you can invest wisely in your most vital organ.
1. Why ECG and SpO2 Matter
Before diving into devices, let’s break down these lifesaving features:
- ECG: Measures electrical heart activity to detect arrhythmias like atrial fibrillation (AFib), a major stroke risk.
- SpO2: Tracks blood oxygen saturation, flagging issues like sleep apnea or respiratory distress.
While no wearable replaces a doctor, these tools provide critical data for proactive care—especially for high-risk groups like seniors, athletes, and those with chronic conditions.
