A cross-sectional study on vitamin D deficiency and cardiac electrophysiology: Evaluating the frontal QRS-T angle.

What Was Tested

This observational study looks at Vitamin D, K2, Magnesium and Zinc.

This study aimed to assess the influence of vitamin D deficiency on the frontal QRS-T (f[QRS-T]) angle on electrocardiograms, a potential marker of arrhythmic risk and cardiac mortality, to address a notable gap in the current understanding.

Why It Was Studied

Vitamin D deficiency is a global health issue, primarily recognized for its role in bone health and calcium absorption.

A total of 282 participants were grouped by vitamin D levels: vitamin D-deficient (<20 ng/mL, n = 185) and non-deficient (≥20 ng/mL, n = 97).

Who Took Part

The abstract describes 357 individuals taking part.

PubMed indexes the participants as adults, middle-aged adults and older adults, both men and women.

In this prospective cross-sectional study, 357 individuals were assessed, with 75 excluded (60 for not meeting criteria, 10 declined, 5 other reasons).

What Was Measured

A total of 282 participants were grouped by vitamin D levels: vitamin D-deficient (<20 ng/mL, n = 185) and non-deficient (≥20 ng/mL, n = 97).

After excluding 7 participants for incomplete tests, data from 275 (deficient: n = 180; non-deficient: n = 95) were analyzed.

What This Means in Plain Language

This is an observational study of Vitamin D, K2, Magnesium and Zinc in 357 individuals.

With several hundred people or more, it is a fairly large study for this kind of research.

The publication is from 2025 (Medicine), a journal based in United States.
