Brugada syndrome is characterized by a coved ST segment in the right precordial leads. The syndrome may cause sudden death due to polymorphic VT resembling torsade.

Takotsubo cardiomyopathy (stress-induced cardiomyopathy) causes a predisposition to torsade. [2, 3]

The acquired conditions that predispose one to torsade either decrease the outward potassium current or interfere with the inward sodium and calcium currents, or fluxes.
