Changes in QT Interval in Maintenance Hemodialysis Patients: Pre-Dialysis, One Hour after Initiation of Dialysis, and Post-Dialysis.
Nguyen VT, Pham BV, Le TTT, Vo CD, Nguyen DQ, Tran NN. Nguyen VT, et al. Blood Purif. 2023;52(5):493-502. doi: 10.1159/000529664. Epub 2023 Mar 30. Blood Purif. 2023. PMID: 36996789
INTRODUCTION: This study aimed to evaluate the effects of dialysis on change of QT interval in pre-dialysis, 1 h after dialysis initiation, and post-dialysis period in patients on maintenance dialysis (MHD). METHODS: An observational prospective study was conducted, includ …

Genetic Basis and Prognostic Value of Exercise QT Dynamics.
van Duijvenboden S, Ramírez J, Young WJ, Mifsud B, Orini M, Tinker A, Munroe PB, Lambiase PD. van Duijvenboden S, et al. Circ Genom Precis Med. 2020 Aug;13(4):e002774. doi: 10.1161/CIRCGEN.119.002774. Epub 2020 Jun 11. Circ Genom Precis Med. 2020. PMID: 32527199 Free PMC article.
BACKGROUND: Abnormal QT interval responses to heart rate (QT dynamics) is an independent risk predictor for cardiovascular disease in patients, but its genetic basis and prognostic value in a population-based cohort have not been investigated. ...We al …

Effect of liver transplantation on QT interval prolongation and autonomic dysfunction in end-stage liver disease.
Mohamed R, Forsey PR, Davies MK, Neuberger JM. Mohamed R, et al. Hepatology. 1996 May;23(5):1128-34. doi: 10.1002/hep.510230529. Hepatology. 1996. PMID: 8621144
Both a prolonged QT interval and disturbance of autonomic nervous system function are markers of poor prognosis in patients with diabetes mellitus and alcoholic liver disease (ALD). We studied the prevalence of abnormal QT interval and autonomic nervous syste …

Is there an abnormal QT interval in sudden cardiac death survivors with a "normal" QTc?
Fei L, Statters DJ, Anderson MH, Katritsis D, Camm AJ. Fei L, et al. Am Heart J. 1994 Jul;128(1):73-6. doi: 10.1016/0002-8703(94)90012-4. Am Heart J. 1994. PMID: 8017288

However, the regression line of the QT interval against the R-R interval was significantly (p < 0.01) altered in SCD survivors compared with normal subjects. These observations suggest that there is abnormal ventricular repolarization (QT interval) despite an apparently

The phenomenon of "QT stunning": the abnormal QT prolongation provoked by standing persists even as the heart rate returns to normal in patients with long QT syndrome.
Adler A, van der Werf C, Postema PG, Rosso R, Bhuiyan ZA, Kalman JM, Vohra JK, Guevara-Valdivia ME, Marquez MF, Halkin A, Benhorin J, Antzelevitch C, Wilde AA, Viskin S. Adler A, et al. Heart Rhythm. 2012 Jun;9(6):901-8. doi: 10.1016/j.hrthm.2012.01.026. Epub 2012 Jan 31. Heart Rhythm. 2012. PMID: 22300664 Free PMC article.
BACKGROUND: Patients with long QT syndrome (LQTS) have inadequate shortening of the QT interval in response to the sudden heart rate accelerations provoked by standing-a phenomenon of diagnostic value. We now validate our original observations in a cohort twice as large. W …

Influence of age, the autonomic nervous system and anxiety on QT-interval variability.
Piccirillo G, Cacciafesta M, Lionetti M, Nocco M, Di Giuseppe V, Moisè A, Naso C, Marigliano V. Piccirillo G, et al. Clin Sci (Lond). 2001 Oct;101(4):429-38. Clin Sci (Lond). 2001. PMID: 11566081
QTVIs were higher in subjects with higher anxiety scores. In younger subjects, sotalol infusion increased both QTVIs significantly, whereas propranolol infusion did not. ...Whether this change is associated with an increased risk of sudden death remains unclear. The associ …

Does abnormal QT interval prolongation reflect autonomic dysfunction in diabetic patients? QTc interval measure versus standardized tests in diabetic autonomic neuropathy.
Veglio M, Chinaglia A, Borra M, Perin PC. Veglio M, et al. Diabet Med. 1995 Apr;12(4):302-6. doi: 10.1111/j.1464-5491.1995.tb00481.x. Diabet Med. 1995. PMID: 7600743

The percentage of patients with a QTc greater than 0.440 s was: absent DAN = 11% (n = 7), probable DAN = 7% (n = 4), definite DAN = 23% (n = 12) (p < 0.05), and the mean (+/- SD) QTc values were 0.403 +/- 0.028 s, 0.405 +/- 0.023 s, and 0.421 +/- 0.026 s, respectively. A signi
