Implication

Guides age-specific ECG interpretation in pediatrics and adults; leaves open validation across disease states and species.

Structured PICO

Population

Healthy newborn infants and full-grown adults, as well as elephants and whales

Outcome

Normal upper limit of the atrioventricular conduction time (PR interval) and duration of the spread of the excitation wave through the ventricles (QRS complex)surrogate

This comparative physiology paper discusses the relationship between heart size and electrocardiographic time intervals across human developmental stages and large mammals.
