Fitaos ECG Smartwatch User Guide

Welcome to the Fitaos ECG Smartwatch User Guide! This comprehensive guide will walk you through the features and functionalities of your Fitaos ECG smartwatch, helping you understand how to measure and interpret electrocardiogram (ECG) data accurately.

What is an ECG?

An ECG, or electrocardiogram, is a medical test that records the electrical activity of your heart over a specific period. It is a vital tool for diagnosing various heart conditions, such as arrhythmias, atrial fibrillation, and more. An ECG provides insights into your heart's rhythm, rate, and overall cardiac health.

How Does a Smartwatch Measure the ECG?

Fitaos ECG Smartwatch uses a technology known as "single-lead ECG" to capture your heart's electrical signals. This technology involves using sensors on the watch's underside to detect and record the electrical impulses generated by your heart as it beats. Here's how it works:

  • Electrodes: The smartwatch has built-in electrodes that come in direct contact with your skin. These electrodes are usually located on the back of the watch, where it makes contact with your wrist.
  • Signal Processing: The watch processes the electrical signals picked up by the electrodes. It amplifies, filters, and digitizes these signals to create a clear ECG waveform.
  • Data Storage: The watch stores the ECG data, which can then be accessed and analyzed using a companion app on your smartphone or through the watch's display.
