[Ambulatory electrocardiographic recording (Holter) at the moment of a sudden death event].

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.

Tpeak-Tend and Tpeak-Tend dispersion as risk factors for ventricular tachycardia/ventricular fibrillation in patients with the Brugada syndrome.

Objectives: Our objective in this study was to evaluate Tpeak-Tend interval (Tp-e) and other electrocardiographic parameters as risk factors for recurrence of life-threatening cardiac events in patients with the Brugada syndrome (BS).

Background: The Tp-e interval in the electrocardiogram (ECG) has been reported to predict life-threatening arrhythmias in the long QT syndrome.

Methods: Twenty-nine patients with the ECG pattern of BS and 29 healthy age- and gender-matched controls were studied.

[Sudden death due to electrical causes in individuals without demonstrable structural cardiac disease. Experience in Cuba].

Sudden cardiac death due to electrical causes in individuals with no evidence of structural heart disease is an important clinical and public health problem, and it is not yet solved. The objectives of this study were: to characterize patients reanimated from a sudden death event of electrical cause; to know the mediated evolution during a period of three years and to study premonitory electrical signs. 42 individuals were studied, 30 were male and 12 female, mean age 37.
