Why the study?
Do pacemaker stimulus wave-form analysis, electronic stimulus interval counting, and radiography predict impending failure in implanted bipolar pacemakers?

A 1% increase in pacemaker rate is a reliable indicator of impending battery depletion in specific bipolar pacemakers, whereas wave-form analysis is less useful.
Answers are grounded in this paper and cite their sources.
May support rate monitoring to detect battery depletion in select pacemakers; leaves open generalizability and needs prospective validation.
One hundred five pacemakers with bipolar electrodes have been observed in a pacemaker clinic serving a rural population. Pacemaker stimulus wave-form analysis and electronic stimulus interval counting were employed. Also, in selected cases, radiographic analysis of battery depletion was performed. Results show that a 1% increase in pacemaker rate is an accurate predictor of impending failure in units that are designed to undergo a rate change with battery depletion, and that radiography is helpful in cases of doubt. Wave-form analysis was useful only when other factors were unequivocally abnormal because of difficulty in standardizing the test.
