Abstract

Severe hypocalcemia is a life-threatening condition that causes serious consequences including cardiomyocytes, which leads to a reduction of cardiomyocyte contractile, arrhythmias, and cardiogenic shock even death in children. It is a serious condition that should be diagnosed and treated promptly. Objectives: to describe clinical characteristics, cardiac function tests, and to approach treatment to patients with hypocalcemia-induced cardiogenic shock. Subjects: 3 patients were diagnosed with severe hypocalcemia, accompanied by a reduction of cardiomyocyte contractile treated at The Vietnam National Children’s Hospital. Method: A case series study including clinical manifestations, history, cardiac function investigation, and treatment approach. Results: 2 out of 3 cases presented cardiogenic shock. Both of these patients presented with a reduction of cardiac contractile function, 2 out of 3 had prolonged QT in ECG. Blood tests revealed a severe reduction of calcium concentration and Vitamin D deficiency. Conclusions: In these cases, hypocalcemia is the only cause that is found out to be associated with the clinical symptoms. Treatment with intravenous calcium, vitamin D supplement, calcitriol show to be effective to recover cardiac myocyte function.
