It has long been established that cardiac contraction and relaxation are primarily the result of recurrent phasic increases and decreases in cytoplasmic calcium ion concentration. Calcium balance plays a crucial role in ventricular repolarization and depolarization. This study aimed to investigate whether there is a relationship between the frontal QRS-T angle and newly diagnosed PHPT patients.</div></div><div><h3>Methods</h3><div>This study was designed as a prospective cross-sectional study. A total of 142 individuals were included, comprising 71 patients over the age of 18 who consented to participate and 71 healthy volunteers.

We focused on participants without existing heart conditions, collecting drug details and daily doses through an online survey.

Significant correlations between SSRIs, and various ECG parameters, with the exception of P duration, were discernible. SSRIs suggested negative correlations with HR, PR, QTC, QRS-axis, RdV5, Sd v2, and reductions in STJ V2, STJ V5, STM V2, STM V5, STE V2, and STE V5 (<em>p</em> &lt; 0.01 or <em>p</em> &lt; 0.05).
