Wellens综合征是以心电图孤立性T波改变及演变为特点的急性冠脉综合征,又称前降支T波综合征。最早在1955年,Pruitt等报道了不稳定型心绞痛患者胸前导联心电图孤立性T波双支对称性深倒置,并逐渐恢复直立的病例(不伴QRS波及ST段改变)。20世纪80年代,Wellens等结合患者的冠脉造影结果,发现上述心电图T波动态改变提示前降支近端中重度 Wellens syndrome is an acute coronary syndrome characterized by the change and evolution of the isolated T wave of ECG, also known as T wave syndrome of anterior descending coronary artery. As early as 1955, Pruitt et al reported that patients with unstable angina pectoris had a deep inversion of solitary T-wave double-limb symmetry and gradually recovered their erection without QRS and ST-segment changes. In the 1980s, Wellens and other patients with coronary angiography results found that the dynamic changes of the T wave ECG showed proximal proximal descending artery moderate to severe
