Patient's question:
Nine-year-old boy has been saying he feels uncomfortable recently. The doctor recommended an electrocardiogram, which showed mild arrhythmia.Doctor's answer:
When arrhythmia occurs and reduces cardiac output, causing shock or near-shock conditions, doctors will use a defibrillator (a medical device that delivers electrical shocks) to deliver electrical shocks to the patient's chest, restoring the heart to a normal rhythm.
