For those of you who might be interested, the ECG in the Apple Watch uses electrodes placed in the case and the Digital Crown and measures electrical signals from the heart. It then produces a waveform. This data is then analyzed and heart rate and rhythm data are used to classify AFib (atrial fibrillation or pretty much an irregular and often rapid heart rate).

The ECG features are available to the Apple Watch Series 4, Series 5, and Series 6.
