    Abstract:
    Arrhythmic sudden cardiac death due to electrical causes is an important clinical and public health problem, which is not yet solved. Ventricular fibrillation is the first cause of the event. It does not adjust to a single model, being a family with diverse electrocardiographic patterns that reveal different disorganization degrees. Many of these deaths happen without witness. We present a patient who was being studied after a first medical visit because of a previous syncope with spontaneous recovery, coursing with left bundle branch block. He was not receiving any antiarrhythmic drug and was asymptomatic at the time. He was wearing a long-term ambulatory electrocardiographic recorder (Holter), which became the sole witness of his death that occurred while he was alone at home. The recording revealed various malignant ventricular arrhythmia (torsades des pointes, ventricular flutter, ventricular fibrillation), immediately preceding events were an increased heart rate, extra-systoles, and left bundle branch block. This is the first recording of the whole sequence of malignant ventricular arrhythmias leading to death in a patient wearing a Hotter device obtained by our department, which has collected 750 Hotter ambulatory records per year for more than 20 years. The literature on the subject is reviewed.
