Early inappropriate shock in a subcutaneous cardiac defibrillator due to subcutaneous air

Inappropriate shock in a subcutaneous cardiac defibrillator due to residual air

Inappropriate shock due to residual air in subcutaneous implantable cardiac defibrillators is not a well-known complication. Obtaining overpenetrated X-rays, recognizing electrocardiogram findings, limiting blunt finger dissection, and switching to sense at another vector are techniques which might lead to avoidance of unnecessary wound exploration or device removal.

Air entrapment causing early inappropriate shocks in a patient with a subcutaneous cardioverter-defibrillator

A 37-year-old man was admitted after experiencing an out-of-hospital cardiac arrest due to ventricular fibrillation. He was successfully resuscitated and had good neurologic recovery. During admission, he was diagnosed with Brugada syndrome and received a subcutaneous implantable cardioverter-defibrillator (S-ICD; Boston Scientific, Marlborough, MA) using a standard technique. For the S-ICD imp...

Subcutaneous emphysema due to compressed air.

Compressed-air tools are of interest by reason of their vibratory action which affects the peripheral circulation of the fingers. Raynaud's syndrome in riveters, pneumatic chisellers and drillers is well known. The harmful effect is almost certainly due to vibration, although cooling of the hands may occur with some pneumatic tools and may be a contributory factor.* Apart from using compressed ...
