Supraventricular tachycardia (SVT) diagnosis can be challenging in young children because P waves may be difficult to identify on a pediatric ECG. In this lesson from our Pediatric ECG course, we evaluate a neonatal ECG by assessing heart rate, QRS complexes, and the subtle ECG findings that support SVT diagnosis. Learn how an accessory pathway causes this common pediatric arrhythmia and produces the characteristic ECG findings of SVT.
