Implication

Distinguishes RVH subtypes by etiology in children; hypothesis-generating and should not yet change practice.

Structured PICO

Can isopotential body surface maps distinguish between different anatomical causes of right ventricular hypertrophy in children?

P
Population
Children with three types of pure right ventricular hypertrophy (secundum atrial defects, valvular pulmonic stenosis, and tetralogy of Fallot)
I
Intervention
Isopotential body surface mapping and epicardial excitation mapping
O
Outcome
Differences in body surface potential distribution and epicardial excitation sequence among the three types of right ventricular hypertrophysurrogate

Isopotential body surface mapping can distinguish between different anatomical causes of right ventricular hypertrophy in children.
