Significados de functional reentry em inglês

Rotors are functional reentry sources identified in clinically relevant cardiac arrhythmias, such as ventricular and atrial fibrillation.

The mechanisms controlling the rotation frequency of functional reentry in ventricular fibrillation (VF) are poorly understood.

Conclusions: (1) A thin layer of activation near the core is responsible for the maintenance of functional reentry.

Methods and results: In six isolated swine ventricular slices, we induced sustained episodes of functional reentry with a stationary core.

Background: The effect of effective refractory period (ERP) shortening on the vulnerability and characteristics of induced functional reentry in the ventricle remain poorly defined.
