Overview
Runaway pacemaker syndrome is a potentially life-threatening malfunction of older pacemaker technologies whereby the pacemaker intermittently fires at a rate of nearly 2000 bpm.
Causes
The malfunction is often related to a low battery voltage.
Diagnosis
Physical Examination
Vital Signs
- Generally the low amplitude pacemaker spikes fail to capture and there is bradycardia.
Complications, Natural History and Prognosis
- Generally the low amplitude pacemaker spikes fail to capture and there is bradycardia.
- Ventricular fibrillation can occur
Treatment
- A magnet should be placed on the chest to stop the potentially life-threatening stimulation.
- The pacemaker should be replaced.
