Unrecognized Failure of a Narrow Caliber Defibrillation Lead: The Role of Defibrillation Threshold Testing in Identifying an Unprotected Individual
Key result
Defibrillation threshold testing during elective generator change identified an unsuspected short circuit in a Riata 1570 defibrillator lead despite normal interrogation parameters.

Implication
DFT testing at generator change may detect silent Riata lead short circuits; hypothesis-generating and should not yet alter practice.

Cite This Study
Leong et al. (2012) conducted a case report in Defibrillator lead short circuit (n=1). Defibrillation threshold testing was evaluated on Identification of lead short circuit. Defibrillation threshold testing during elective generator change identified an unsuspected short circuit in a Riata 1570 defibrillator lead despite normal interrogation parameters.
