Treatment
Although it is clear that treatment should be established when there are symptoms, the approach to use in asymptomatic patients is still under debate. [revespcardiol.org]
Prognosis
Two-to-one AV block is an infrequent manifestation with a poor prognosis that can be present since the fetal stage in the form of persistent bradycardia. [revespcardiol.org]
Etiology
It presents when the QT interval is prolonged, regardless of the etiology. It is a polymorphic ventricular tachycardia due to reentry, characterized electrocardiographically by continuous twisting of the QRS axis around an imaginary line. [revespcardiol.org]
Prevention
Frequencies programmed below 70 beats/min117 are not useful for preventing ventricular arrhythmia. [revespcardiol.org]
