Abstract

• The pacemaker syndrome is a complex of clinical signs and symptoms related to the adverse hemodynamic and electrophysiologic consequence of ventricular pacing in the absence of other cause.
  The following illustrates a case of pacemaker syndrome proven by cardiac catheterization. A 64-year-old female patient who had been previously managed with single chamber pacemaker(VVI mode) due to sick sinus syndrome, suffered from chest discomfort, headache, dizziness, lightheadedness.
  We thought that she suffered from pacemaker syndrome and changed single chamber pacing to dual chamber pacing. At that time we performed cardiac catheterization perioperatively.
  Pulmonary capillary wedge pressure, amin pulmonary arterial pressure, right atrial pressure and right ventricular pressure were normalized after the change and she didn't feel any symptoms.
