This directly destabilizes myocardial membranes, leading to a prolonged QT interval and a high risk of Torsades de Pointes, a fatal ventricular arrhythmia. Cardiac monitoring and intravenous calcium replacement are the top priorities to prevent cardiac arrest.
While hyperkalemia is also cardiotoxic, profound hypocalcemia poses the most acute and immediate arrhythmia risk in the context of TLS. Do not delay treatment to first address other lab values.
