Ventricular fibrillation undersensing due to air entrapment in a patient implanted with a subcutaneous cardioverter defibrillator

Abstract

This is the first report of a significant time-to-therapy prolongation due to entrapped air. This case emphasizes the importance of ensuring that all the air in the tunneling channel is eliminated once the lead is in place. Also, it represents an insightful example of how the S-ICD automatic sensitivity algorithm works
