Reversible congestive heart failure associated with hypocalcemia: A case report

Figure 1 Electrocardiography on admission showed a prolonged QT interval corrected for heart rate. The QT interval corrected for heart rate equaled 0.560 s.

Figure 2 Chest computed tomography on admission showed bilateral lung infection and bilateral pleural effusions. Black arrows showed bilateral pleural effusion; White arrows showed bilateral lung infection.

Figure 3 Head computed tomography on admission showed symmetric calcification in basal ganglia. No sign of infraction or hemorrhage was observed; White arrows: Calcification.

Figure 4 Echocardiography on admission. Left ventricular enlargement and left ventricular systolic function was significantly reduced. The ejection fraction was 28.48%.

Figure 5 Echocardiography 2 d after admission. Left ventricular systolic function improved after calcium supplementation. The ejection fraction was 40.80%.

Figure 6 Echocardiography at the 1-mo follow-up. The size and systolic function of the left ventricle continued to recover. The ejection fraction was 48.50%.

Figure 7 Echocardiography at the 4-mo follow-up. Left ventricular size and left ventricular systolic function returned to normal. The ejection fraction was 65.60%.
