Abstract :
The quality of repolarization duration measurements is influenced by noise. The variability of 6 standard measures are compared on the basis of 35 Holter ECGs from a practical field study in part highly disturbed. RTmax corrected by Bazett´s formula was found to be the most robust parameter in the given population
