Risk of occurrence of electromagnetic interference from the application of transcutaneous electrical nerve stimulation on the sensing function of implantable defibrillators

EuropacePublished

  • Pilot safety study
  • standardized test protocol

Authors' conclusion

Overall, only intermittent and minor EMI were detected.

Study context

Population
Patients with modern implantable cardioverter-defibrillator (ICD)/cardiac resynchronization therapy (CRT) defibrillators (55 models, 4 manufacturers) undergoing transcutaneous electrical nerve stimulation (TENS) at cervical spine and thorax, high-frequency (80 Hz) and burst-mode (2 Hz)
Participants
107 patients
Outcome
Occurrence of EMI from TENS on ICD sensing
