Tracing
Résumé
This tracing reflects once again the need to systematically check the defibrillator memories in order to avoid misdiagnosis of atrial arrhythmia. The detection of spontaneous ventricles and the temporarily inhibition of the biventricular stimulation was secondary to the detection of an external noise on the atrial lead. At the time of the detection of this episode, the patient was using a poorly insulated appliance. The treatment in this context consists in the identification of the emitting source to prevent further recurrences.
