Some clarifications
The recording speed
In many countries, the paper speed is 1 cm/min, whereas in the Netherlands it is generally 2 cm/min, and in North America and Japan it is almost exclusively 3 cm/min.
The paper scales used in each unit should be those with which healthcare professionals are most familiar, as interpretation of the tracing depends on pattern recognition.
