We report a case of inappropriate shock from TWOS during postural change.

Routine exercise testing could not predict T‐wave oversensing in a patient after a subcutaneous implantable cardioverter‐defibrillator implant
Subcutaneous implantable cardioverter-defibrillators (S-ICDs) are susceptible to T-wave oversensing (TWOS) caused by high rate-dependent QRS-T morphology changes. We experienced an inappropriate S-ICD shock due to TWOS, which could not be predicted by routine exercise testing. A newly available high-pass filter might be effective for avoiding this.

Introduction The clinical benefits of implantable cardioverter-defibrillator (ICD) therapy have been widely documented in clinical studies of selected patient populations. Subcutaneous ICD (S-ICD) is a valid alternative to transvenous ICDinpatientswhodonot require cardiac resynchronization or antibradycardia or antitachycardia pacing, and has the additional advantage of avoiding possible acute ...
متن کاملInappropriate shocks from a subcutaneous implantable cardioverter-defibrillator due to oversensing during periods of rate-related bundle branch block
The subcutaneous implantable cardioverter-defibrillator (S-ICD) is a novel technology with proven efficacy in sudden cardiac death prevention; however, there is a lack of long-term safety data. We describe the case of a 55-year-old female patient implanted with an S-ICD due to idiopathic ventricular fibrillation, who subsequently presented with inappropriate shocks leading to ventricular fibril...
متن کاملA case of inappropriate implantable cardioverter defibrillator therapy induced by T-wave oversensing due to hyperkalemia.
There have been reports of hyperkalemia-induced T-wave oversensing in patients with implantable cardioverter defibrillators (ICDs). However, a comparison of T-wave amplitudes and morphologies between the surface 12-lead electrocardiogram (ECG) and ICD electrogram has not been reported. We present the case of a 70-year-old man who received inappropriate ICD shocks due to hyperkalemia-induced T-w...
متن کاملUnusual cause for an increase of the sensing integrity counter in a patient with inappropriate implantable cardioverter-defibrillator therapy.
We describe the case of a patient who presented with multiple implantable cardioverter-defibrillator (ICD) shock discharges 12 months after device implantation. Upon device interrogation, intermittent oversensing of electrical noise and potential ICD lead failure were suggested by a significant increase in the sensing integrity counter (SIC), a cumulative count of very short ventricular sensed ...
