Approach to EKG interpretation:Rate Rhythm AxisIntervalsUps and Downs
What are some challenges to interpreting Pediatric EKG’s? • age-related changes -- such as? • movement artifact
Take a look at the settings • Standard amplitude is ___ mm/mV • Paper speed is ___ mm/s
Double-check the settings • Standard amplitude is 10 mm/mV • Paper speed is 25 mm/s

Rhythm • What defines a sinus rhythm? • P wave before every QRS • QRS after every P wave • Normal PR interval for age • Normal P wave axis • Upright I and aVF
Rhythm • What defines a sinus rhythm? • P wave before every QRS • QRS after every P wave • Normal PR interval for age
Which quadrant represents a “normal” QRS axis in an adult?
Extreme Right Axis Deviation
Axis • QRS axis is usually directed toward a hypertrophied ventricle • What is the expected axis in a newborn?
Axis • What is the expected axis in a newborn? Large R ventricle = Right axis deviation
Normal neonatal EKG in a 1-week-old infant. QRS axis is 125°, which would be considered right axis deviation in an adult. Note the tall R waves in V1, V2, and V3, which are normal.

Ups and Downs: Look at ST segment, T wave progression, ?extra blips (U waves, etc)
