title: An appropriate defibrillation threshold obtained by the combined connection between two shock leads and ICD generator.
abstract: A 60-year-old man with arrhythmogenic right ventricular cardiomyopathy was readmitted for the battery exchange of his implantable cardioverter-defibrillator (ICD). Since (i) he had been treated with a dual-coil shock lead (Sprint Fidelis, Medtronic) and (ii) pre-operative venography showed mild collateral flow to the left subclavian vein, a single-coil lead was additionally implanted. However, the single-coil defibrillation system was unable to terminate the induced ventricular fibrillation (VF), thus dual defibrillation shock pathways were created using the connection to the superior vena cava coil of the Fidelis lead. The combined connections of the two shock leads provided an appropriate margin of the defibrillation threshold.
