Pediatric ventricular tachycardia

Ventricular tachycardia (VT) refers to three or more consecutive pulsations that originate in the ventricle. The ventricular rate of ventricular tachycardia in children is 120 beats / min (100 beats / min in adults). Children often have irritability, paleness, and shortness of breath. Older children may complain of palpitations, pain in the precardiac area, and severe cases may include syncope, shock, and congestive heart failure. The report accounts for about 6% of tachyarrhythmias. It is a severe tachyarrhythmia that can develop into ventricular fibrillation and cause sudden cardiac death. Hemodynamic changes are prone to occur due to ventricular tachycardia, which often causes panic, chest tightness, dyspnea, Darkness, syncope, and shock. Therefore, ventricular tachycardia is a pediatric emergency and requires urgent treatment. Pediatric VT includes a set of different ventricular tachycardia in terms of etiology, pathogenesis, clinical manifestations, electrocardiogram characteristics, prognosis and treatment response. At present, there is no consensus on the minimum heart rate limit for infants with ventricular tachycardia. The heart rate of ventricular tachycardia in the population should be more than 25% higher than the normal sinus heart rate.
