Pseudo-Malfunction, Recording ArtifactA patient was implanted with a DDDR pacing system in 2001 and was referred by his new primary care physician for a detailed pacing system evaluation. At the time of the follow-up evaluation, it was discovered that the implanted pacing system was not routinely utilized at the facility. Electrocautery-Induced VTThis case illustrates the potential, admittedly rare, life-threatening interaction between electrocautery and permanent pacemakers. Atrial Premature Beats and Ventricular Intrinsic PreferenceA patient was seen for an initial evaluation with his pacemaker having been implanted at another institution. The reported indication for pacing was sinus node dysfunction. There was no comment as to the status of AV nodal conduction. The Event Histogram reported 10% ventricular pacing and 63% atrial pacing. Symptomatic MVP and APPThe patient is an 81-year-old male whose pacemaker was implanted two years previously at another hospital for “intermittent AV block, bradycardia and paroxysmal atrial fibrillation and flutter.” High Ventricular Rate Stored EGM - VT Induced AVNRTAn elderly patient who was implanted with an SJM Identity® XL DR model 5376 pacemaker for sick sinus syndrome was seen in follow-up. She had been complaining of periodic rapid palpitations associated with marked weakness and pre-syncope, but she never fainted. She was asymptomatic during a Holter study. Intermittent Oversensing in the Early Post-Implant PeriodA 72-year-old patient has complete heart block and a 25% ejection fraction. His cardiac status is stable with only mild heart failure symptoms readily responsive to standard pharmacologic therapy. Implantation of a dual-chamber ICD was uncomplicated. Prior to closing the pocket, intermittent pauses were noted on the monitor.
