While these usually occur in the setting of structural heart disease, they may also be a consequence of an acute process or an inherited predisposition of an individual's cardiac tissue to life-threatening arrhythmias.</p><p id="par0115" class="elsevierStylePara elsevierViewall">These primary cardiac electrical diseases, although uncommon, are usually detected in younger<a class="elsevierStyleCrossRef" href="#bib0015"><span class="elsevierStyleSup">3</span></a> and otherwise healthy individuals, often with tragic consequences.</p><p id="par0120" class="elsevierStylePara elsevierViewall">SQTS is a recently described entity included in the group of inherited primary electric disorders. As originally proposed by Gussak in 2000,<a class="elsevierStyleCrossRef" href="#bib0020"><span class="elsevierStyleSup">4</span></a> it involved the association of a significantly shortened QTc interval on the surface ECG with atrial fibrillation and sudden cardiac death.</p><p id="par0125" class="elsevierStylePara elsevierViewall">Since its description in two families,<a class="elsevierStyleCrossRef" href="#bib0025"><span class="elsevierStyleSup">5</span></a> our understanding of this rare entity has evolved, but there are still many questions to answer, particularly regarding its incidence and prognosis.</p><p id="par0130" class="elsevierStylePara elsevierViewall">Our patient was initially assessed in the ED with a clinical diagnosis of syncope. While this is a common complaint in the ED, representing up to 3% of all visits, its causes range from benign vasovagal reactions to life-threatening cardiac arrhythmias. In this clinical setting, the presentation of recurrent syncope at rest, without known precipitating events, suggested a potentially serious underlying process.</p><p id="par0135" class="elsevierStylePara elsevierViewall">After documentation of an arrhythmic cause, the patient's severe electrical instability could have been associated with an acute myocardial ischemic process, but this was ruled out by persistently negative serum troponin and a normal coronary angiogram. In the absence of other precipitating causes, with ECGs showing a shortened QT interval without structural heart disease, a presumptive diagnosis of SQTS was made. To our knowledge, this is the first known documentation on a 12-lead ECG of R-on-T extrasystoles in a short QT-related arrhythmic episode.</p><p id="par0140" class="elsevierStylePara elsevierViewall">In contrast with long QT interval, which may be brought on by external factors, including certain drugs, there is no known association between medication and a shortened QT interval. However, due to an overlap of QTc values between healthy population cohorts and patients with SQTS,<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,7</span></a> hyperkalemia, hypo- or hypercalcemia, sinus tachycardia, hypothermia, acidosis or digoxin therapy must be excluded. A case of short QT related to prolonged resuscitation efforts and hypothermia has also been described,<a class="elsevierStyleCrossRef" href="#bib0040"><span class="elsevierStyleSup">8</span></a> but this was not the case in our patient.</p><p id="par0145" class="elsevierStylePara elsevierViewall">Similarly to the long QT syndrome, there appears to be significant overlap of QTc values between healthy population cohorts and patients with SQTS.<a class="elsevierStyleCrossRefs" href="#bib0030"><span class="elsevierStyleSup">6,7</span></a> This suggests that an abbreviated QT interval is not in itself the cause of an increased risk of arrhythmia, but may be a surface surrogate for the arrhythmogenic substrate in SQTS patients. As such, a diagnosis of short QT syndrome should only be considered following careful assessment of the 12-lead ECG, in an appropriate clinical setting (history of syncope or aborted sudden cardiac death, positive family history), as suggested by the Gollob score.</p><p id="par0150" class="elsevierStylePara elsevierViewall">As the QT interval is heart-rate dependent, use of the Bazett formula allows estimation of the real QT interval (as measured at 60 bpm) at any heart rate. Some caution must be used in its application, as the formula has been reported to undercorrect (yielding erroneously high QTc intervals) at heart rates above 90 bpm.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">14</span></a> However, measuring the QT interval at a heart rate of 60 bpm is not always feasible in clinical practice as it may require the use of beta-blockers or Holter monitoring, and the Bazett formula remains an acceptably simple and effective tool at the bedside.</p><p id="par0155" class="elsevierStylePara elsevierViewall">The described cellular mechanism behind idiopathic short QT interval is usually related to gain-of-function mutations in potassium channels; these lead to a shortened action potential duration through accelerated cardiomyocyte repolarization. So far, six different genotypes have been conclusively associated with SQTS (<a class="elsevierStyleCrossRef" href="#tbl0010">Table 2</a>), but genetic testing was negative in 71% of the reported cases,<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> suggesting that other genetic mutations remain to be identified.</p><elsevierMultimedia ident="tbl0010"></elsevierMultimedia><p id="par0160" class="elsevierStylePara elsevierViewall">Although genetic testing has so far shown a low diagnostic yield, a hereditary component was found in 71.9% of index cases in the study by Gollob et al.<a class="elsevierStyleCrossRef" href="#bib0010"><span class="elsevierStyleSup">2</span></a> However, application of a diagnostic score to family members may underestimate the prevalence of SQTS due to the incomplete penetrance of inherited cardiac electrical disorders.

In theory, pharmacological therapy with a QT-prolonging drug should be effective in correcting the short QT interval; however, most QT-prolonging drugs, such as flecainide or sotalol, are ineffective in these patients.<a class="elsevierStyleCrossRef" href="#bib0045"><span class="elsevierStyleSup">9</span></a> Recent data show that most QT-prolonging drugs have the highest affinity for the inactivated state of the potassium channel Kv11.1.<a class="elsevierStyleCrossRef" href="#bib0050"><span class="elsevierStyleSup">10</span></a> Curiously, in SQTS, Kv11.1 inactivation is usually abolished, conferring relative resistance to the action of these drugs.

The recognition of this rare syndrome has allowed reclassification of individuals who would previously have been classified as having idiopathic ventricular fibrillation, as is the case with our patient. Any suspected cases of SQTS should be referred to specialized centers where they can be offered a multidisciplinary approach and disease-specific therapeutic interventions, such as quinidine or ICD implantation, according to SQTS risk stratification.
