Popis: We report on a case of a 78-years-old patient with a subcutaneous implantable cardioverter defibrillator (S-ICD) and an episode of a sustained ventricular tachycardia (VT) at a rate slower than the programmed shock zone. Because of T-wave oversensing the device interpreted it as fast VT that triggered the delivery of an “inappropriately appropriate shock” that terminated it. The patient had again more VT episodes but after programming the SMART pass algorithm (previously programmed “OFF”) the device showed no longer frequent T-wave oversensing and no additional inappropriate shocks occurred.
