Understanding Heart Rate Monitoring Technology

Heart rate monitoring technology plays a vital role in wearable devices. It allows users to track their heart rate during workouts, monitor their recovery, and even keep an eye on their overall cardiovascular health. But how does it all work?

The Basics of Heart Rate Measurement

At its core, heart rate monitoring involves detecting the pulse or number of beats your heart makes in a minute. Most heart rate monitors utilize one of two technologies: optical sensors or electrocardiograms (ECGs).

Optical Sensors

Optical sensors, used in devices like smartwatches and fitness bands, operate using photoplethysmography (PPG). This technology emits light into the skin and measures the light that is reflected back. Since blood absorbs light differently than other tissues, variations in light reflection can determine changes in blood volume, which correlates to heartbeats.

Electrocardiograms (ECGs)

On the other hand, ECGs measure the electrical activity of the heart and can provide more accurate readings. Devices with ECG capability work by placing electrodes on the skin, providing a more precise measurement of heart rate and rhythm.

How Accurate Is the Samsung Health Heart Rate Monitor?

Samsung Health implements optical sensor technology in most of its devices. Various factors can affect the accuracy of heart rate readings, including the surroundings, skin type, and the watch’s placement on the wrist.
