ECG normal values (Ped(z)-style) is a electrocardiography tool commonly applied in Cardiology. Age-stratified pediatric ECG reference limits (heart rate, PQ/PR, QRS, Q in III/aVF/V5/V6) from DOB and reference date. Embedded UTMB summary of Park & Guntheroth (2006); Q aVF/V5 interpolated where the source table lists only III/V6. Same role as Ped(z) ECG normals; not affiliated with pedz.de. Use the interactive calculator for inputs, limitations, and primary references.

Not a substitute for clinical judgment. Verify critical values with primary literature, local protocols, and specialist input when appropriate.
