Pediatric EKG Screening Diagnosis Follow up
Normal Values (Davignon)
P wave Atrial Depolarization Lead II Duration (≤3y max=0.09s, >3y max=0.1s) Amplitude (max=2.5mm) Lead V1 Axis Arrhythmias
QRS Complex Ventricular Depolarization Duration (V5) Amplitude (high, low if R+S ≤ 5mm for limb leads & ≤ 10mm for precordial leads) Axis Morphology (QRSR’)
T Wave Ventricular repolarization Amplitude ( high if ≥ 7mm in limb leads & ≥ 10mm in precordial leads ) Axis
T Wave Axis I,IIpositive after 48 hours aVfpositive after 5 days aVrnegative V3r, V1negative (6 days to 6 years) V6positive
P Wave Axis Abnormalities
RVH qR (V1) Pure R (V1) T wave abnormalities (V1) R(V1) > P98 S(V6) > P98 R/S(V1) > P98 RSR’(V1) RAD (after 3 years of age)
RVH Pure R
RVH Progressive T wave abnormalities
RVH RSR’ 1 year at least 10mm Normal QRS duration
LVH ST segment & T wave abnormalities (I, II, aVf, V5, V6) R(V6) > P98 S(V1) > P98 R(V6)+S(V1) > P98 Deep q (V6) (> 4mm) LAD
BVH Criteria for both RVH & LVH RVH & normal forces of LV LVH & normal forces of RV R+S (mid-precordial leads) (Katz-Wachtel Index)
BVH * * *
Atrial Enlargement Lead II (2.5×2.5) Lead V1 (1×1)
RAE Tall P wave Large initial deflection (V1)
LAE Broad P wave Large terminal deflection (V1)
