Short article but it’s interesting

Interesting, but I’ve never had it effect my readings on ECG or Kardia, device.
We are all uniquely unique🙂

Any sort of movement on the patient's part during an ECG will produce artifact, which someone trained to interpret ECGs should be able to recognize. In fact, if they were present for the recording they should have known it wasn't going to be a valid recording from the start. And if they weren't present, the person doing the recording should have discarded it or at least made a note that movement artifact is present.
