Web21 de jun. de 2024 · Factors of a normal ECG reading. P wave- P wave amplitudes rarely exceed two and a half squares (0.25 mV). The duration of the P wave should not exceed three small squares (0.12 seconds). QRS complex- The normal duration (interval) of a QRS complex is between 0.08 and 0.10 seconds, or between 80 and 100 milliseconds. WebMost newborns have an electrical axis greater than 135° (98% confidence interval 58° to 168°). After birth, the electrical axis gradually normalizes ... R/S ratio in V1 and V2 is smaller than normal. R/S ratio in V5 and V6 is greater than normal. Abnormally large Q-waves in V5-V6. ST-depression and T-wave inversion in V5-V6.
