case_images: Investigations revealed a serum sodium level of 120 mmol/L, a magnesium level of 1.5 mmol/L, a creatine kinase (CK) level elevated to 1,688 U/L, and a normal sinus rhythm on electrocardiogram (EKG) without ischemic changes, widened QRS, or prolonged QTc interval (Figure 1 and Figure 2).
