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 interval. The PR interval begins at the start of the P wave and ends at the beginning of the Q wave.. It represents the time taken for electrical activity to move … WebPacing activity may be visible or invisible, depending on e.g the type of pacemaker, intrinsic cardiac activity, etc. The cardinal manifestation of pacing on surface ECG is the stimulation artifact (Figure 1). In atrial pacing, the stimulation artifact precedes the P-wave. In ventricular pacing, the stimulation artifact precedes the QRS complex.
