WebJan 22, 2024 · The mean QT interval without RBBB was 369.39 ± 37.38, reaching 404.22 ± 39.23 after inducing RBBB. ΔQT was calculated as 34.83 ± 17.61, and the ratio of ΔQT/QRS with RBBB was almost 23%. Our formula is: (QT with RBBB − 23% × QRS). Subtraction of 25% instead of 23% seems more straightforward and practical.
