Improved
The 12-lead's numbers now come from the tracing you see
Before
The PR, QRS and QT beside the normal tracing came from the older model's settings rather than the beat on screen, so the PR read 26 ms short and the QRS 14 ms long, and the ST segment was dead flat.
After
The numbers are measured off the drawn beat, QTc uses Fridericia's formula and is labelled QTcF, and V2 and V3 show the small upsloping ST that most normal ECGs have.
