Electrocardiogram teaching that was given in the context of the Technical Workshop at the Montreal Children's Hospital neonatology unit on November 10, 2022. The recording is available here (in english).
Enseignement de l'électrocardiogramme qui a été donné dans le cadre de l'Atelier technique à l'unité de néonatologie de l'hôpital de Montréal pour enfants le 10 novembre 2022. L'enregistrement est disponible ici (en anglais). Les diapositives sont également disponibles en PDF en cliquant ici (Section ECG).
Excellent presentation by Laila Wazneh (NNP at the Montreal Children's Hospital) and Dr Satit Manopunya on Supra-Ventricular Tachycardia. This was presented in the context of the Neonatal Cardiology Rounds and mentored by Dr Tiscar Cavalle (pediatric cardiologist). We thank the presenters for their exceptional presentation and preparation, as well as for agreeing to share the slides with the NeoCardioLab community.
Vraiment super atelier disponible en ligne via l'Association des cardiologues du Québec par Dr Jean-Marc Côté (CHU de Québec) et Dre Anne Fournier (CHU Sainte-Justine) sur l'Interprétation interactive des tracés ECG pédiatriques. Cet atelier est en français seulement.
Right Ventricular Hypertrophy (RVH)
Definite RVH
R wave in V1 > 98th percentile for age
Upright T wave in V1 between 1 week and 6 years of age
QR pattern in V1 (Q wave > 1 small box)
QR in V3R/V4R with R wave > 7 mm or > mean for age
RSR' pattern: R' > 15 mm if < 1 year old, or > 10 mm if > 1 year
Possible RVH
Deep S wave in V6 > 98th percentile for age
Pure R wave in V1 in children > 6 months
Right axis deviation with prominent right ventricular forces
Left Ventricular Hypertrophy (LVH)
Definite LVH
Child > 5 years: R wave in V6 > 30 mm
Child < 5 years: R wave in V6 > 98th percentile for age
Possible LVH
Child > 5 years: R wave in V6 between 98th percentile and 30 mm
S wave in V1 > 5 mm above 98th percentile for age
Q waves in V6 or III > 98th percentile with prominent LV forces
Biventricular Hypertrophy (BiVH)
Definite BiVH
R + S wave in any lead > 60 mm in child < 1 year or > 55 mm in child > 1 year
Possible BiVH
Criteria for both LVH or RVH, exceeding the mean in the opposite lead
QT Interval Interpretation
Normal QTc
< 445 ms (any age, any sex)
< 455 ms in adolescent females
With sinus arrhythmia: QTc with shortest RR < 470 ms and normal T waves
Prolonged QTc
QT interval > 500 ms on any beat (including Holter)
Normal ECG Variants (No Comment Required)
Sinus arrhythmia
Sinus bradycardia > 50 bpm in children > 5 years
Nonspecific ST-T changes
Early repolarization
Critical ECG Findings (Require Immediate Attention)
Definitive WPW pattern
Second- or third-degree AV block
Bundle branch block or widened QRS
SVT, atrial flutter/fibrillation, IART, VT, VF, junctional tachycardia
Evidence of acute ischemia
Pericarditis
Pacemaker non-capture
Atrium
RAE: P wave in lead II > 3 small boxes
LAE: P wave wider than 3 small boxes in lead II, P-terminal force in V1 > 1 box x 1 box and negative
