Wellens syndrome is a clinical-electrocardiographic entity also referred to as 
left anterior descending (LAD) coronary T-wave syndrome or acute coronary T-wave 
syndrome. It is a complex of symptoms and signals indicating the existence of an 
undesirable condition secondary to critical high-grade proximal stenosis of the 
LAD coronary artery characterized by the association of prior history of acute 
coronary syndrome with little or no elevation of markers of myocardial damage 
(unstable angina) and characteristic electrocardiographic changes consistent 
with subepicardial anterior ischemic pattern (persistently symmetrical, deep 
negative and broad-based T waves) or plus-minus T waves with inversion of the 
terminal portion in the LAD coronary artery territory (V1 through V5 or V6). We 
present a case of a variant of Wellens syndrome that reveals association and, 
transitorily, the criteria described in literature for left septal fascicular 
block.
