An 83-year-old woman with a dual-chamber pacemaker presented with fatigue and an ECG showing atrial and ventricular pacing artifacts without ventricular capture, suggesting right ventricular lead dislodgement.
Case Report (n=1)
This case highlights the ECG presentation of ventricular safety pacing triggered by right ventricular lead dislodgement.
ECG CHALLENGEAn 83-year-old woman with a dual-chamber pacemaker presented to the emergency department with 1 day of fatigue and generalized weakness.The pacemaker was placed 1 year before presentation at an outside facility for second-degree heart block.No previous ECGs were available for review in our system.On arrival, her heart rate was 64 beats/min, and her other vital signs were within normal limits.The 12-lead ECG was recorded during evaluation (Figure 1).We can see an initial atrial pacing artifact and a second ventricular pacing artifact that do not result in ventricular capture.What happened to the right ventricular lead based on the ECG below?Please turn the page to read the diagnosis.
Singh et al. (Mon,) conducted a case report in Right ventricular lead dislodgement (n=1). Dual-chamber pacemaker was evaluated on ECG diagnosis of right ventricular lead dislodgement. An 83-year-old woman with a dual-chamber pacemaker presented with fatigue and an ECG showing atrial and ventricular pacing artifacts without ventricular capture, suggesting right ventricular lead dislodgement.
