TASER conducted electrical weapons and implanted pacemakers and defibrillators

Introduction: Conducted electrical weapons (CEW) have generated controversy in recent years regarding their effect on heart rhythm and on their suspected interaction with implanted devices such as the pacemakers and ICDs (implantable cardioverter defibrillators). We review the current evidence available on device interactions and pre-sent a new case series of 6 patients. Literature: We used the available case reports and animal studies on TASER or CEW related publications in PubMed. Conclusion: Oversensing of TASER CEW discharges may cause noise reversion pacing in pacemakers and inappropriate detection of VF in ICDs. The nominal 5-second discharge is sufficiently short that neither clinically significant inhibition of bradycardia pacing nor inappropriate ICD shocks have been reported. Current evidence indicates that CEW discharges do not have adverse effects on pacemakers and ICDs.
