Why the study?
Does the Hodges formula improve the stability of QTc and JTc interval assessment across different heart rates compared to other formulae in patients with complete bundle branch block?
Does the Hodges formula improve the stability of QTc and JTc interval assessment across different heart rates compared to other formulae in patients with complete bundle branch block?
The Hodges, Nomogram, and Framingham correction methods provide the most stable assessment of QT/JT intervals across different heart rates in patients with bundle branch block, whereas Bazett's formula exaggerates heart rate-dependency.

Supports Hodges formula for stable QTc/JTc across heart rates; leaves open prospective validation in bundle branch block.
