This makes them handy tools for keeping an eye on your heart's health without needing to visit a doctor every time.
Key Takeaways:
- Smartwatches like Apple Watch and Fitbit Sense can detect irregular heartbeats, helping catch AFib early and keep your heart healthy.
- These smartwatches use cool tech like ECG and light sensors to monitor your heart, but always check with a doctor for real medical advice.
Technology Behind AFib Detection
Electrocardiogram (ECG) Technology
ECG technology in smartwatches works by measuring the electrical signals that make your heart beat. When you place your finger on the watch's sensor, it creates a circuit with your heart. The watch then records the electrical activity and looks for irregularities that might indicate AFib. This is similar to what you'd get in a doctor's office, but it's right on your wrist.
Photoplethysmography (PPG) Sensors
PPG sensors use light to measure how much blood is flowing through your veins. These sensors shine a light into your skin and measure the amount of light that bounces back. Changes in the light's reflection can indicate changes in your heart rate and rhythm. While not as detailed as an ECG, PPG sensors are great for continuously monitoring your heart's activity.
Algorithm and Data Analysis
Smartwatches use complex algorithms to analyze the data collected from ECG and PPG sensors. These algorithms look for patterns and irregularities that might suggest AFib. When the watch detects something unusual, it can alert you so you can take action. The data is often stored in an app, allowing you to share it with your healthcare provider for a more detailed analysis.
