A vortex ring, also called a toroidal vortex, is a torus-shaped vortex in a fluid or gas; that is, a region where the fluid mostly spins around an imaginary axis line that forms a closed loop. The dominant flow in a vortex ring is said to be toroidal, more precisely poloidal.
Torsades de pointes, a French term that literally means twisting of the points, is a lethal form of ventricular tachycardia named for its hallmark feature: polymorphic QRS complexes that appear to twist around the isoelectric line. Without treatment, few patients survive Torsades de pointes (TdP) once it develops. The key to preventing sudden cardiac death lies in early detection of warning signs. TdP is easily distinguishable from conventional ventricular tachycardia (VT), which has monomorphic QRS complexes.
