Short QT syndrome is a recently recognized cause of cardiac rhythm disorders, including sudden cardiac death. Although the syndrome is rare, its potential lethality justifies routinely screening the electrocardiograms of patients with syncope or unexplained atrial or ventricular arrhythmias to look for this diagnosis. This review discusses recent advances in the understanding of the pathogenesis of this syndrome and outlines some of the challenges in establishing the diagnosis.
短 QT 综合征是一种新近被认识到的心律失常病因，包括心源性猝死。尽管该综合征较为罕见，但鉴于其潜在致死性，应对晕厥或不明原因房性或室性心律失常患者的心电图进行常规筛查，以寻找这一诊断。本文讨论了对该综合征发病机制的新近认识，并概述了确立诊断所面临的一些挑战。
