Electrical Signs predictors of malignant ventricular arrhythmias.

Recurrence of malignant ventricular arrhythmia is frequent in cardioverter-defibrillators related patients. The risk stratification is difficult, there are numerouselectrocardiographic predictors but his sensibility and specificity are not absolute. The limit between normal and pathological is not defined, besides thecomplexity of ventricular arrhythmias. We expose different electrocardiographic predictors that can help to better individual risk stratification.
