WebJul 23, 2024 · Parts of the ECG explained P waves. P waves represent atrial depolarisation. In healthy individuals, there should be a P wave preceding each QRS complex. PR … WebP wave: When present P-waves are normal. QRS: Normal. Conduction: Normal. Rhythm: Basic rhythm is regular*. *In a type I SA block, the P-P interval shortens until one P wave is dropped. *In a type II SA block, the P-P intervals are an exact multiple of the sinus cycle, and are regular before and after the dropped P wave.
