Implication
NAO drives a minority of inappropriate ICD shocks via external/connector noise; leaves open whether targeted fixes reduce events in practice.

Population
2,000 patients who received implantable cardioverter defibrillator (ICD) and cardiac resynchronization therapy defibrillator (CRT-D) shocks and were followed by a remote monitoring system

Outcome
Incidence and causes of noise/artifact and oversensing (NAO) resulting in ICD shockssafety
External noise and lead/connector issues are the primary causes of inappropriate ICD shocks related to noise, artifact, and oversensing.
