Abstract:
The SMART Pass filter (Boston Scientific) aims to reduce inappropriate shocks (IASs) from subcutaneous implantable cardioverter-defibrillators by filtering out low-frequency signals such as T waves. However, this filter is deactivated in the presence of diminished R-wave sensing. We describe a case of IAS in the setting of extensive intra-abdominal hemorrhage.
