Wellens' syndrome is characterized by T-wave changes in electrocardiogram (EKG) during pain-free period in a patient with intermittent angina chest pain. It carries significant diagnostic and prognostic value because this syndrome represents a pre-infarction stage of coronary artery disease involving pro...

急性心包炎的炎症累及心外膜下浅层心肌时,引起心外膜下心肌炎(subepicardial myocarditis),从而产生损伤电流,造成心肌复极异常。由于急性心包炎是炎症累及心外膜下浅层心肌导致,通常不涉及深层心肌,因此ST-T改变幅度小,其ST段抬高程度不高于0.5mV,也不会出现异常Q波。 由于心脏综合向量指向心尖部,因此ST段向量与QRS电...
Wellens syndrome is not always an acute process. It can develop over days to weeks. The ECG pattern often develops when the patient is not experiencing chest pain. When the patient does experience chest pain, the ST segment and T-wave pattern can appear to normalize into hyperacute upright ...
In addition, we would like to emphasize the clinical significance of T-wave inversion in anterior precordial leads is an acute coronary syndrome as well. We recently had a 64-year-old white man who presented to the ED with a chief complaint of substernal chest heaviness that woke him up ...
and 0.6% within 5 days.4 Differential diagnosis of T wave inversion comprises extensive clinical circumstances such as acute coronary syndrome, past myocardial infarction, acute pulmonary embolism, central nervous system injury, persistent juvenile T wave pattern, digitalis effect, left ventricular hyper...
Wellens综合征1例报道 Wellens综合征1 例报道 毛龙燕,袁良,杨秀君,李雪苓 摘要Wellens综合征为急性冠脉综合征(ACS)的特殊类型,由于其不具有ACS所具有的心电图或者心脏肌钙蛋白I(cTnI)的特异性变化,故而在临床中容易误诊,而耽误病人的最佳治疗时间及治疗方式,从而影响病人的预后㊂本研究所述为在我科诊治的1例...
Wellens综合征(Wellens Syndrom ,WS)是极易发展为恶性心血管事件的非持续性ST段抬高型急性冠脉综合征(non-persistent ST-segment elevation acute coronary syndrome,NSTE-ACS)的一种高危亚型,其特点是特征性T波和胸痛程度极其不符,即心绞痛发作时T波直立(伪正常化),而心绞痛缓解时胸导联(V2-V4为主)出现深倒置或...
Wellens' syndrome consists of a history suggestive of an acute coronary syndrome and biphasic or deeply inverted T waves in ECG leads V2–V3. A shortcut review was carried out to establish whether this ECG pattern identifies patients with a critical left anterior descending artery stenosis. Six ...
