The Polar OH1 has been validated in a PLOS ONE paper as far accuracy is concerned:
https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0217288
The authors found a 95 % – 99 % agreement between a g.Nautilus ECG device and a Polar OH1.
The 64 channel g.Nautilus device costs according to a g.Nautilus demo video at least 50 000 USD. There is no validation study available for the Verity Sense to this date.
We suggest to wear four Polar OH1 sensors simultaneously to maximize the accuracy, two on the left upper arm und lower arm, and another two on the right upper arm and lower arm:

You can wear another Polar OH1 mounted to your swimming goggles for measuring heart rate from your temple.
Connect it via MQTT (Polar Sensor Logger app):
to Home Assistant & InfluxDB for sensor data processing. From InfluxDB, we can further process the data with the InfluxDB client for Python.
Polar keep selling the Polar OH1, the scientific community will be grateful to you.
