Detection of Pacemaker Malfunction

The success of an implanted cardiac pacemaker is dependent upon the establishment of a harmonious relationship between the artificial pacemaker and the human receiver. Failure of a pacemaker system may arise from an electronic or mechanical defect of the pacemaker, a physiological problem, or from a poor relationship between the normal function of pacemaker and host. Such malfunctions may necessitate the repair, replacement, or repositioning of a pacemaker component or removal of a source of external interference. True pacemaker malfunctions must be clearly distinguished from pseudo-malfunctions, where there is no pacemaker system defect. These situations may, variously, require the repair of faulty testing equipment, reassessment of falsely interpreted test data, or treatment of the patient for an unrelated disorder. For simplicity, this paper will be confined to malfunctions associated with the synchronous ventricular inhibited pacing system. It can be seen from the complexity of the situation that proper investigation and interpretation of data is critical to the comprehension and correction of a pacemaker problem.
