- Normal Peds EKG Variations
- Right heart dominance
- From infancy to adulthood ventricular dominance transitions from a relatively thicker RV in utero/infancy to thicker LV as adults
- Right axis deviation
- Tall R waves in V1-V3
- RSR' in V1
- Deep S waves and Q waves in lateral leads
- Juvenile T wave pattern in V1-V3
- Small cardiac size = shorter intervals, faster rate
- J-point depression
- Early repolarization
- Sinus arrhythmia
- Right heart dominance
- NOT Normal Peds EKG Variations
