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. WebJunctional escape rhythm is a regular rhythm with a frequency of around 40–60 beats per minute. In case of sinus arrest (or any scenario in which atrial impulses do not reach the atrioventricular node), junctional escape rhythm may be life-saving.
