In young children, the right ventricle normally extends to the right side of the sternum. To appropriately display right ventricular potentials, ECGs for children in the under five‐year age group must include an extra lead (‘V4R’) on the right side of the chest at a point analogous to the left sided V4.
Precordial leads:
V4R: 5th intercostal space, right midclavicular line
V1: 4th intercostal space, right sternal border
V2: 4th intercostal space, left sternal border
V3: use this lead for V4R, must label as such on ECG.
V4: fifth intercostal space, right midclavicular line
V5: anterior axillary line, same horizontal plane as V4
V6: midaxillary line, same horizontal line as V4.
Limb leads:
Place on top part of arm or leg (less muscle interference)
