Electrocardiographic Manifestations: Pediatric ECG

Accurate Detection of Paediatric Ventricular Tachycardia in AED

“…There exist well-known electrophysiological differences between adult and paediatric rhythms (Chan et al, 2008;Rustwick et al, 2007). Differences between children and adults in both the rate and conduction of VF have been identified, although these differences do not affect VF sensitivity (Cecchin et al, 2001).…”

“…The duration of the QRS complex is shorter in children than in adults because of the smaller cardiac muscle mass in children (Chan et al, 2008), while the QT interval is similar in children and adults. The QT interval, however, depends on and is normally adjusted to the heart rate.…”

“…SVT is usually associated with an accessory atrioventricular pathway in neonates and young children. In adolescents and adults, the most common cause of SVT is an atrioventricular nodal reentry tachycardia (Chan et al, 2008).…”

“…Although SVT is more common in children, tachycardias of ventricular origin do occur in paediatric patients (Chan et al, 2008). As the normal QRS complex is of shorter duration in children than in adults, VT is more difficult to diagnose in young children.…”

AED for Paediatric Use, Implications in the Design of Shock Advice Algorithms

“…As a result of the maturation of the cardiovascular system, the stroke volume increases so the heart rate lowers maintaining the overall cardiac output (Chan et al, 2008). In this section we report the heart rates of the NSR, SVT and VT records from our database.…”
