See [paediatric ECG RCG](https://www.rch.org.au/clinicalguide/guideline_index/Basic_Paediatric_ECG_interpretation/) **6 differences btwn adult and paediatric ECG** - HR >100 - Rightward QRS axis  - T wave inversion in v1-v2 (juvenile t-wave pattern) - dominant R in v1 - RSR' in V1 - short pr interval <120ms and QRS duration (<80ms) - slightly peaked P waves - slightly long QTc **Things to look for** - [[Syncope ECG patterns#Hypertrophic Cardiomyopathy|HCM]] (only HOCM if ovstruction of outflow tract → collapse on exertion) - apical HCM (widespread lateral T waves, more common japan and korea) - Dagger-like because of *septal hypertrophy* - [[Syncope ECG patterns#ARVC]] → differentiate epsilon wave from J wave by *epsilon comes off qrs complex*, j wave is separate - [[Syncope ECG patterns#Brugada]] → can be unmasked by fever. Low threshold to admit kids with fever who have brugada - [[Syncope ECG patterns#WPW]] → see [[SVT paeds]] - [[Syncope ECG patterns#Long QT]]
