Key result
Telemetered intracardiac electrograms successfully identified spurious signals (amplitude 2-14 mV) from active fixation leads as the cause of inappropriate pacemaker pauses in three cases.
Case Report (n=3)
Telemetered intracardiac electrograms are clinically useful for diagnosing design-dependent lead malfunctions causing spurious signals and pacemaker oversensing.

Telemetered electrograms may aid diagnosis of lead-related oversensing; case reports leave broader utility and generalizability open.
Joseph Sarmiento (1990) conducted a case report in Inappropriate pacemaker pauses due to false signals (n=3). Telemetered intracardiac electrograms was evaluated on Identification of spurious signals causing apparent oversensing. Telemetered intracardiac electrograms successfully identified spurious signals (amplitude 2-14 mV) from active fixation leads as the cause of inappropriate pacemaker pauses in three cases.
