Comment: Magnesium deficiency can lead to various arrhythmias, including ventricular premature beats, atrial fibrillation, supraventricular tachycardia, torsades de pointes, supraventricular ectopic beats, bigeminal rhythm, and ventricular fibrillation.

Inspection of the figure shows a bigeminal rhythm with each of the long R-R intervals measuring 0.71 sec and each of the short R-R intervals, 0.46 sec.
