Short QT Syndrome Patients


Rapid Ventricular Repolarization in Rodents: Electrocardiographic Manifestations, Molecular Mechanisms, and Clinical Insights. Gussak I, Chaitman BR, Kopecky SL, Nerbonne JM. J Electrocardiol 2000:33(2):159-170

This article examines specific ECG and EP features of ventricular repolarization in rats and mice, and the role of depolarization-activated potassium-currents in mediating the unique features of ECG recordings in these rodents. The authors points out that the absence of a distinct isoelectric interval between the QRS complex and the T wave, accompanied by a relatively short QT interval, are common features of ECG recordings in mice and rats, but not in ECGs in guinea pigs.

Prevalence of Very Short QT Intervals in Patients with Idiopathic Ventricular Fibrillation and Implanted ICD Filipecki A, Trusz-Giuza M, Lubinski A. Circulation 2004;110(17):2350

Abstract of presentation from Katowice and Gdansk in Poland of a retrospective analysis of ECGs from 42 patients with structurally normal hearts who had survived sudden cardiac death and diagnosed with idiopathic cardiomyopathy.Five patients or 12% were found to have QTc intervals =/< than 300 msec leading the authors to conclude: “the presence of short QT interval is not rare in patients with idiopathic ventricular fibrillation”.

Unfortunately no ECGs were shown during the presentation, and the authors made the mistake defining short QT interval based upon QTc corrected by Bazett’s formula, and not upon an uncorrected QT interval measured at a heart rate close to 60 bpm. (Unfortunately, the patients heart rates were not mentioned in the abstract). The conclusion from this study was, therefore, most likely incorrect, and no other study has since found such a high incidence of short QT interval in patients with idiopathic VF.

Genetic analysis in 200 subjects with the longest and the shortest QTc from a cohort of 2008 healthy subjects suggest, that genetic determinants located in KCNQ1, KCNE1, KCNH2 and SCN5A influence QTc length in healthy individuals and may represent risk factors for arrhythmias or cardiac sudden death in patients with cardiovascular disease.

Long QT Syndrome with Cardiac Arrest and Transient Short QT sue to a Novel KCNH2 Mutation causing both Loss and Gain of Function .De Ferrari GM, Crotti L, Lundquist AL, Pedrazzini M, Insolia R, Ferrandi C, Vicentini A, Vaccari D, Schwartz PJ, George Jr. ALHeart Rhythm 2005;2(5):P2-35

An 18-year old female with recurrent syncope and long QT (QTc 500 ms). While Holtermonitored during syncope with seizures she revealed the presence of a long episode (105 sec) of Torsades des Pointes VT preceded by ventricular bigeminy with marked repolarization changes. At termination of the VT, a phase of atrial fibrillation with slow ventricular response and an extremely short QT interval (QTc 250 ms).Molecular screening disclosed a novel KCNH2 mutation causing an inframe deletion of a conserved lysine residue in the S6 segment. Heterologous expression of the deletion allele alone did not produce current, while coexpression with WT-HERG resulted in channels exhibiting a substantial shift in the voltage-dependence of activation to more hyperpolarized potentials. This results in significantly larger tail currents at negative potential and in significantly smaller tail currents at positive potential, compared with WT-HERG. This pattern of channel dysfunction, either loss or gain of function in a voltage dependent manner, can account for the peculiar ECG features exhibited by the patient.

These results illustrate the potential for phenotype overlap between the long and the short QT syndrome.

Short QT Interval and Atrial Fibrillation in Patients without Structural Heart Disease. Poglajen G, Fister M, Radovancevic B, Vrtovec B. JACC 2006;47(9):1905-1907

Letter to the editor.

The authors compared the QTc intervals in 165 consecutive healthy subjects presenting with an episode of AF to the QTc intervals in 165 age-and gender matched subjects without evidence of arrhythmias. Short QTc interval (<400 ms) was an independent predictor of AF occurrence in multivariate analysis with QTc intervals in patients with AF significantly shorter than in the control group.

The authors speculate whether pathophysiological mechanisms that lead to shortening of the QT interval (even of mild degree) might also play an important role in genesis of AF in structurally normal hearts.

Long QT syndrome and short QT syndrome: how to make correct diagnosis and what about eligibility for sports activity Napolitano C, Bloise R, Priori SG.. J Cardiovasc Med 2006;7(4): 251-256

At the time of this article only 23 cases of SQTS from six different families had been reported. The article, therefore, mainly addresses issues regarding LQTS.

Possible Increased Risk of Cardiac Arrhythmias in Patients with Acguired Short QT Interval Assadi R. Chang R. Abdipour A, Pai SM, Jutzy KR.. JACC 2007;March 6:836-6

Abstract from a presentation at the ACC meeting in 2007.

Electrocardiographic Biomarkers of Ventricular Repolarisation in a Single Family of Short QT Syndrome and the Role of the Bazett Correction Formula Extramiana F, Maury P, Maison-Blanche P, Duparc A, Delay M, Leenhardt A.. Am J Cardiol 2008;101:855-860

Based upon ECG recordings from 27 members of a family where one had survived an episode of SCD in the setting of SQTS it was concluded, that the Bazett correction formula is not appropriate for making a diagnosis of SQTS. Based upon their definition of SQTS (QT ≤ 320 msec and QTc ≤ 340 msec), three additional members were considered to have SQTS and a high number (16) had shorter than normal QT interval and classified as suspected SQTS (ECG-based QT was ≤ 320 msec and/or QTc Bazett interval was > 340 msec and ≤ 380 msec).

A big limitation of this study is the lack of genotyping.

(The index case, his brothers and his mother have been described previously by Maury P et al in Heart Rhythm 2005;2:1135-1137)

Electromechanical Coupling in Patients with the Short QT Syndrome: Further Insights into the Mechanoelectrical Hypothesis of the U Wave Schimpf R, Antzelevitch C, Haghi D, Giustetto C, Pizzuti A, Gaita F, Veltmann C, Wolpert C, Borggrefe M.. Heart Rhythm 2008;5:241-245

Echocardiography and electrocardiography was performed in 5 SQTS patients from 2 unrelated families with a history of SCD and 5 age-matched and gender matched control subjects. In SQTS patients the end of the T wave preceded aortic valve closure by 111 +/- 30 ms compared to –12 +/- 11 ms in control subjects. The interval from aortic valve closure to the beginning of the U wave was 8 +/- 4 ms in SQTS patients and 15 +/- 11 ms in controls. Thus the inscription of the U wave in SQTS patients coincided with aortic valve closure and isovolumetric relaxation, supporting the hypothesis that the U wave is related to mechanical stretch.

Thus, substantial stretch during isovolumetric phase may induce local membrane repolarization, generating a voltage gradient in the left ventricular myocardium detected as the U wave in the surface ECG.

They are, however, able to point out important conceptual differences between the Short QT Syndrome and the hERG channel activation.

Diagnostic Miscues in Congenital Long-QT Syndrome. Taggart NW, Haglund CM, Tester DJ, Ackerman MJCirculation 2007;115:2613-2620

Even though this article is about LQTS and not SQTS there are many similarities between the two syndromes in making the right diagnoses and especially the right interpretation of the QT interval. The authors found that diagnostic concordance was present for less than one third of patients who sought a second opinion regarding the diagnosis of LQTS.

The Short QT Syndrome. Proposed Diagnostic Criteria. Gollob MH, Redpath CJ, Roberts JDJ AM Coll Cardiol 2011;57:802-12

A ‘Schwartz score’ for short QT Syndrome Veltman C, Borggrefe M.. Nat Rev. Cardiol. 2011;8:251-252

Several possible limitations of the score system proposed by Gollob et al. are discussed. The lack of a control group of ‘normal’ individuals with shorter than normal QTc intervals is pointed out and it is stressed that at best the scoring system can do is to estimate the probability of having the disease, not to make the diagnosis. Also the omission of using data from an electrophysiological study or exercise testing in the scoring system is emphasized.

Proposed Diagnostic Criteria for Short QT Syndrome Are Badly Founded Bjerregaard P.. J Am Coll Cardiol 2011;58:549-550

In this letter to the editor of JACC several errors in the article by Gollob et al is pointed out, and the limitations of using Bazett’s formula to correct the QT interval in patients with possible SQTS emphasized. It is the opinion of the author: “that the proposed diagnostic criteria for SQTS are poorly founded and should be used with great caution”.
