Key Clinical Message 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.
