 ====== Heart rate variability validation and derivatives ======
-Researchers from the [[https://www.rug.nl/staff/i.m.nolte/|University Medical Center Groningen]] performed a validation of the [[ECG]] from participants at [[1a_visit_1|1A visit 1]] and [[2a_visit_1|2A visit 1]]. Additionally, derivative variables have been created. ([[sections]]: [[physical state]] ([[ECG]]) and [[secondary & linked variables]])).\\
