Wellens syndrome

Wellens syndrome include Wellens waves in patients who have had typical chest pain that has now resolved. This sign is specific for a critical LAD stenosis. Originally these waves were described as Pattern A (biphasic) and Pattern B (inverted), but it has been suggested that these waves evolve from biphasic to inverted over time. Similar waves may be seen with reperfusion after catheterisation and stenting.
