Why the study?
Do different averaging devices for non-invasive detection of ventricular late potentials yield concordant results in the same patients?
Do different averaging devices for non-invasive detection of ventricular late potentials yield concordant results in the same patients?
Different averaging devices for detecting ventricular late potentials show significant variability in results, primarily due to differences in interpretation methods and QRS end determination.
No takes yet. Share an insight, caveat, or question.
Device variability in late potential detection cautions clinical interpretation; leaves open need for standardized methods in research.
Oeff et al. (1986) studied this question.
