Why the study?
The exact differences between the TU wave complex of Andersen-Tawil syndrome type 1 (ATS1) and healthy individuals remained to be investigated.
Does high frequency ECG analysis of the TU wave complex differentiate patients with Andersen-Tawil syndrome type 1 from healthy individuals?
Population
13 patients with ATS1 and age-matched healthy individuals
Comparison
ATS1 patients with KCNJ2 mutations vs age-matched healthy controls
Design
Case-control study

High-frequency ECG may distinguish TU wave features in ATS1; leaves open diagnostic or prognostic utility pending validation.
Does high frequency ECG analysis of the TU wave complex differentiate patients with Andersen-Tawil syndrome type 1 from healthy individuals?
High frequency ECG analysis reveals that U-wave-related temporal parameters, particularly BUe, and U-wave-specific independent components can differentiate ATS1 patients from healthy individuals.
Horigome et al. (2019) studied this question.
