Why won't the pixel watch 3 record an ECG when great rate is over 120bpm?

My cardiologist recommended I but this watch for the ECG function to monitor my atrial tachycardia in case it becomes atrial fibrillation, but the pixel watch 3 won't record my ECG when my heart rate is over 120 bpm (i.e. when I'm having tachycardia).
Why won't it do this?

@Anitabrunning   The Pixel Watch records a 30 second single lead (Lead I) ECG.  Its purpose is to look for signs of atrial fibrillation.  It uses a machine algorithm.  This is a medically regulated feature, meaning Fitbit submitted clinical data to the FDA about its accuracy up to, but not beyond 120 bpm.  It can't read any other types of tachycardia.
