Abstract：
Wolff-Parkinson-White (WPW) syndrome is a condition associated with tachycardia due to accessory pathways in the heart, and it is one of the most common causes of tachycardia in infants and children. WPW may also be associated with mitochondrial encephalomyopathy, lactic acidosis, stroke-like episodes (MELAS syndrome) or LEOPARD syndrome (LS). We report a case of pre-excitation WPW syndrome in a 17-year-old man who was brought to the hospital by ambulance following the collapse. WPW syndrome type A was diagnosed from precordial leads. Electrocardiography (ECG) revealed a short PR interval, delta waves, and positive waves with dominant R in all pericardial leads. Blood test results showed an isolated elevated ALT level. Subsequent echocardiography was unremarkable, with an ejection fraction of 55%, apart from septal and inferior wall dyssynchrony. With regard to the past medical history, he had sensorineural deafness (SND) since childhood and had a family history of SND. Consequently, the patient was transferred to the cardiac electrophysiology department at another hospital after consultation and underwent ablation. A successful post-ablation electrocardiogram revealed the resolution of the WPW syndrome signs and post-ablation features, such as peak T waves.
摘要：
Wolff-Parkinson-White（WPW）综合征是一种与心脏附属通路引起的心动过速相关的疾病，它是婴儿和儿童心动过速的最常见原因之一。WPW也可能与线粒体脑肌病有关，乳酸性酸中毒,中风样发作（MELAS综合征）或LEOPARD综合征（LS）。我们报告了一名17岁男子的预激WPW综合征病例，该男子在倒塌后被救护车送往医院。从心前区导线诊断出A型WPW综合征。心电图（ECG）显示PR间期较短，三角洲波,和所有心包导联中R占优势的正波。血液测试结果显示单独的ALT水平升高。随后的超声心动图无异常，射血分数为55%,除了间隔和下壁不同步。关于过去的病史，他从小就患有感音神经性耳聋（SND），并有SND家族史。因此,患者在会诊后被转移到另一家医院的心脏电生理科,并接受了消融治疗.成功的消融后心电图显示WPW综合征体征和消融后特征的消退，例如峰值T波。
