Hypocalcemia and Tachycardia Induced Cardiomyopathy

In managing these patients, electrolytes like calcium and magnesium are important part of work-up, apart from those described by the authors. Both hypocalcemia and hypomagnesemia have been reported as causes of arrhythmias in children as well adults [2,3]. Since this child had two such episodes, he also needs to undergo electrophysiological study to look for any conduction pathway defect, which is rare but a important cause to look for in patients with repeated arrhythmias.
