Wandering pacemaker rhythm is typically associated with which clinical feature?

• A. Rarely causes symptoms
• B. Precedes blocks or Asystole
• C. Requires immediate pacing
• D. Causes severe chest pain

Answer: (A)

Wandering pacemaker is a benign atrial rhythm in which the pacemaker site shifts among the SA node and multiple atrial foci, producing varying P-wave morphologies and an irregular rhythm. Because the ventricular rate typically stays normal and hemodynamics are preserved, this pattern often causes no symptoms or only mild palpitations. It does not usually need pacing, and it does not imply impending blocks or Asystole. Severe chest pain isn’t a feature of this rhythm; that would point to something like ischemia. If the rate climbs above 100 bpm, the pattern is called multifocal atrial tachycardia, which can be more symptomatic and clinically significant. So, the best summary is that it rarely causes symptoms.
