In a routine monitor electrocardiogram few hours after implantation of a dual-chamber pacemaker, there was a suspicion of ventricular oversensing leading to failure to output. Pulse oximeter plethysmographic wave signal virtually excluded this suspicion. This case report demonstrates the clinical utility of initial pulse oximeter wave analysis in excluding pacemaker failure to output.
