8 paź 2024 · Placement of paediatric ECG leads. 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 alternate lead (‘V4R’) on the right side of the chest, at a point analogous to the left-sided V4.
It’s the placement of the ECG leads (labeled with a V) that we’re focusing on here. (Quick note: At PCCO, we follow adult guidelines for pediatric patients weighing 90 pounds or more. See below for infants, toddlers, and children weighing less than 90 pounds.)

Video: Demonstration of proper ECG lead placement on an older child/adult mannikin and troubleshooting steps. Lead stickers can be placed below the clavicle rather than the shoulder to prevent muscle twitch artifact.
28 sty 2010 · Precordial lead placement. Step 1: Determine the Rate and Rhythm. Rate. Using lead II or the lead with the least artifact, calculate the approximate heart rate by counting the number of large boxes between 2 QRSs: heart rate = 300 ÷ number of large boxes between QRSs (Figure 2).
