- Electrocardiogram (ECG or EKG): This method records the electrical activity of the heart, providing highly accurate heart rate readings.
- Chest Strap Monitors: These devices use electrodes to capture heart rate data directly from the heart, typically offering superior accuracy over wrist-based monitors.
- Photoplethysmography (PPG): A non-invasive method that measures blood volume changes using light, commonly found in wearable fitness trackers.
Optical Heart Rate Monitoring: This technology employs light-based sensors that shine a light into the skin and measure the amount of light absorbed or reflected, which varies with blood flow. While generally accurate during steady-state activities, it may struggle with rapid movement or high-intensity workouts due to motion artifacts.
Electrocardiogram (ECG or EKG): By placing electrodes on the skin, this method captures the electrical impulses produced by heartbeats, delivering precise readings. ECG monitors are often found in clinical settings or advanced fitness devices, offering the highest level of accuracy but typically requiring more setup than other methods.
Chest Strap Monitors: These are worn around the chest and use conductive electrodes to measure electrical signals generated by the heart. They are well-regarded for their accuracy, especially during vigorous exercise, as they are less susceptible to interference from movement compared to wrist-based monitors.
Photoplethysmography (PPG): This technology is widely used in fitness trackers and smartwatches, relying on light sensors to detect blood volume changes in peripheral tissues. While convenient and user-friendly, PPG can be less accurate during high-intensity activities or when the wearer has poor circulation or skin tone variations.
