INAPPROPRIATE S-ICD PATIENT RECEIVES FALSE POSITIVE SHOCKS

Souhrn

Subcutaneous implantable cardioverter defibrillator (S-ICD) protects the patients at risk for sudden cardiac death while leaving the heart and vasculature untouched. It provides life-saving therapy, but may also deliver inappropriate therapy. Presented case demonstrates a possibility of S-ICD therapy induction due to double-counting. It was original caused by lack of suitable sensing vectors and the solution was possible just particularly. As the inter-individual variability of subcutaneous cardiac signal is considerable, the patient screening should be necessary for identification of such patients, which have an unsuitable subcutaneous sensing signals.
