This case underscores the association between severe hyponatraemia and TC, highlighting the need for careful electrolyte management in patients with acute cardiac symptoms. The exact mechanisms linking hyponatraemia and TC remain to be elucidated, but this case contributes to the limited literature on hyponatraemia-induced TC, emphasizing the importance of recognizing and addressing this electrolyte imbalance to prevent cardiac complications.
