Q: What Is a Heart Health Tracker, and How Does It Work?
A: A heart health tracker is a device or app designed to monitor key metrics related to your cardiovascular system. These tools help you track real-time data like heart rate, blood pressure, oxygen saturation, and even more advanced measurements like heart rate variability (HRV) and electrocardiogram (ECG) readings.
Most modern trackers use sensors—such as optical heart rate monitors, accelerometers, or electrodes—to collect data. Wearable devices like smartwatches or fitness bands continuously measure your heart rate, while more advanced trackers (like medical-grade ECG monitors) provide deeper insights into heart rhythm and potential irregularities. The data is then synced to an app, where you can analyze trends, set goals, and share information with your healthcare provider if needed.
