The FastStart Research app is designed to be used with optical PPG sensors that can measure heart rate, heart rate variability, and atrial fibrillation (AF) and are increasingly being deployed in smartphones and wearable devices such as Google’s Fitbit range and the Apple Watch.
PPG uses an infrared light to measure changes in blood volume in blood vessels, and is a low-cost alternative to the electrocardiogram (ECG) functions found in some high-end wearables, with some key advantages including continual scanning for heart rate irregularities rather than relying on spot checks.
