WebAbnormal ECGs could result in another 20 pages or more, we will discuss a couple of important abnormal patterns derived from what we call a “current of injury”. When an area of the heart experiences a current of injury, due to damaged cells, this current of injury ends up causing the baseline “isoelectric” line to either raise or lower. 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.
