Background
Vitamin D (VitD) deficiency has been associated with various cardiovascular pathologies. However, limited data are available regarding cardiac arrhythmias in VitD deficiency. Therefore, we aimed to assess whether atrial electromechanical delay (AEMD) measured by tissue Doppler imaging (TDI), which is an indicator for atrial fibrillation (AF) development, is prolonged in patients with VitD deficiency as compared to control group.
Methods
In this cross-sectional study a total of 28 VitD deficient and 56 age-, gender- and BMI-matched VitD sufficient healthy participants were enrolled. Both intra- and inter-AEMD were calculated by TDI. The correlation between clinical variables and AEMD were analyzed.
