Sleeping with the fishes: electromagnetic interference causing an inappropriate implantable cardioverter defibrillator shock

Abstract: A 60-year-old man with a cardiac defibrillator implanted due to previous ventricular fibrillation arrest and ischaemic cardiomyopathy received a shock while cleaning his fish pond. At the time, his immersed arm was close to a submersed water pump, but the patient was asymptomatic. As a result of the shock he lost consciousness, but collapsed backwards, away from the pond. Interrogation of the device revealed a high-frequency artefact that was sensed by the device and triggered a shock. Device parameters were o… Show more

“…Furthermore, given the growth of the Internet of Things (IoT), the potential for EM interactions is increasing. Sources of EM interference that caused patient illness included wireless networks [20], swimming pool generators [85], water pumps [86], electrostatic discharge from fleece clothing [87], co-existing implanted devices [88], surgical equipment [89], plastic toys [90], hot tubs [91], electrical installations [92] and consumer devices such as Fitbits [93]. Asher et al describe a case of a patient's e-cigarette interacting with an implantable cardioverter-defibrillator (ICD), and a 55F with an ICD which reverted to magnet mode due to interference with the patient's fitness watch [93].…”

“…Jacuzzis have been described as possible sources of current leak, although this is the first description of resultant inappropriate ICD therapy as far as we are aware. Other water‐based EMI sources include swimming pools, showers, and pond pumps . Confirming lead integrity on device interrogation is helpful in distinguishing internal versus external sources of noise.…”
