There are few reports on the use of wearable cardioverter-defibrillators（WCDs）in children. Case 1 was a naturally healthy 9-year-old boy. Ventricular fibrillation（VF）developed during a marathon and he was resuscitated. He was diagnosed with vasospastic angina and took a Ca antagonist, but developed VF again. After that, coronary CT revealed an abnormality in the left coronary artery, coronary artery repair surgery was performed, an implantable loop recorder was implanted, and WCD was introduced. Case 2 was a 12-year-old boy with severe aortic valve stenosis who, developed VF while playing football. After resuscitation, aortic valve replacement surgery was performed and WCD was introduced. Both cases showed good wearing compliance and understanding of the equipment. There was no arrhythmia event during wearing, and an electrophysiological study and an exercise stress test were conducted before finishing wearing, and it was thought that the risk of recurrence of VF was low, and the implantable cardioverter-defibrillator was avoided. The chest circumference of case 1 was lower than the minimum size, but the belt was sewed shorter and he was able to wear it. The use of WCD by children after cardiopulmonary arrest resuscitation was very useful in determining treatment.
