The ECG of a patient during sinus rhythm shows preexcited QRS pattern, with rS pattern in lead V1, transition in lead V2, and positive inferior leads. Following the stepwise algorithms, the location of accessory pathway (AP) was identified at anteroseptal region. However, the precordial transition in lead V2 indicates mid-septal or posteroseptal AP. The mismatch suggested multiple APs and 5 APs were identified by electrophysiologic study. This case highlights the importance of detailed analysis of ECG in order to achieve adequate ablation.

Congenital short QT syndrome is a very low prevalence inherited primary arrhythmia syndrome first reported in 2000 by Gussak et al., who described two families with a short QT interval, syncope, and sudden cardiac death. In 2004, Ramon Brugada et al. identified the first genetic type of this entity. To date, a total of nine genotypes have been described. The diagnosis is easy from the electrocardiogram (ECG), not only due to the short QT duration, but also based on other aspects covered in this review. During 24-h Holter monitoring, paroxysmal atrial fibrillation spontaneously converting to sinus rhythm may be found. Even though the T wave may appear symmetric on the ECG, the T loop of the vectorcardiogram confirms that the T wave is constantly asymmetric due to the presence of dashes closer to each other in the efferent branch. In this review, we also describe the minus-plus T wave sign that we have described in a previously published article. In addition to congenital causes, we briefly highlight the existence of numerous acquired causes of short QT interval.
先天性短 QT 综合征是一种发病率极低的遗传性原发性心律失常综合征，由 Gussak 等人于 2000 年首次报道，他们描述了两个具有短 QT 间期、晕厥和心脏性猝死的家族。2004 年，Ramon Brugada 等人确定了该病症的第一个遗传类型。迄今为止，共描述了九种基因型。从心电图（ECG）上很容易做出诊断，这不仅是因为 QT 时间短，还基于本综述中涉及的其他方面。在 24 小时 Holter 监测中，可能会发现阵发性心房颤动自发转为窦性心律。尽管 T 波在心电图上看起来是对称的，但矢量心电图的 T 环证实，由于传出支中存在相互靠近的短划痕，T 波始终是不对称的。在这篇综述中，我们还介绍了我们在以前发表的一篇文章中描述过的负加 T 波征象。除先天性原因外，我们还简要强调了导致短 QT 间期的多种后天性原因。
