GALIZIO, Néstor O. et al. Undersensing of Spontaneous Ventricular Fibrillation as a Cause of Sudden Death in a Child. Rev. argent. cardiol. [online]. 2008, vol.76, n.4, pp. 317-320. ISSN 1850-3748.
In few cases implantable cardiodefibrillators have been reported to undersense ventricular fibrillation, and most of them happened during the measurement of defibrillation thresholds. This type of undersensing has been suggested as a potential cause of sudden death. In this case report we describe a 4-year old boy with hypertrophic myocardiopathy who suffered a spontaneous episode of ventricular fibrillation with a great alternation in the amplitude of local ventricular electrograms. The episode was undersensed by the device and therefore it was not treated, causing the child's death.
