8 Οκτ 2024 · Causes syncope if self-terminating or cardiac arrest if prolonged (i.e. degenerates to VF). Ventricular Fibrillation Also extremely rare in children and associated with congenital cardiac abnormalities.
The most common pediatric arrhythmias are tachycardias, and the most common type is supraventricular tachycardia, originating from or above the atrioventricular node and HIS bundle. Ventricular tachycardias are less common but more dangerous.
Treat the cause: Physiological response: Crying. Exercise. Anxiety/fear. Pain. Identify precipitant. Compensatory mechanism: Respiratory/circulatory failure. Hypovolaemia. Sepsis.
Cardiac Arrhythmias in Children Eric A. Biondi, MD* Introduction Although most childhood arrhyth-mias are benign, prompt and correct diagnosis of a serious rhythm distur-bance in a child can be lifesaving. Such rhythm disturbances may arise at any age and have a wide variety of presentations. This article discusses various pediatric arrhythmias ...
Characterise and treat major arrhythmias in children. Key points. • Use age-appropriate reference ranges when interpreting a child's ECG. • The right ventricle can be dominant up to the age of 3 yrs, and this is reflected by dominant R waves in Lead V1. •
Why worry? Implications of Arrhythmias • Symptoms – May lead to disruption to daily activities – Dizziness or loss of consciousness injury • Ventricular dysfunction – If incessant and/or unrecognized • Sports participation and physical activity – Many pediatric arrhythmias require no restrictions – Children often self-limit
between infants and children; (2) severity of symptoms; (3) presence of ventricular dysfunction suspected to be caused by frequent ectopy; and (4) type of ventricular arrhythmia (e.g., uniform vs polymorphic, frequent ectopy vs sustained VT, and right ventricular outflow tract vs other sites). The committee
