Drug-induced atrial fibrillation.
Kaakeh Y, Overholser BR, Lopshire JC, Tisdale JE. Kaakeh Y, et al. Drugs. 2012 Aug 20;72(12):1617-30. doi: 10.2165/11633140-000000000-00000. Drugs. 2012. PMID: 22834678 Free PMC article. Review.
Atrial fibrillation (AF) is a common cardiac arrhythmia that is associated with severe consequences, including symptoms, haemodynamic instability, increased cardiovascular mortality and stroke. While other arrhythmias such as torsades de pointes and sinus bradycardia are m …

The heart and the liver.
Møller S, Dümcke CW, Krag A. Møller S, et al. Expert Rev Gastroenterol Hepatol. 2009 Feb;3(1):51-64. doi: 10.1586/17474124.3.1.51. Expert Rev Gastroenterol Hepatol. 2009. PMID: 19210113 Review.
Pathophysiological mechanisms include reduced beta-adrenergic receptor signal transduction and defective cardiac electromechanical coupling. However, the QT interval is prolonged in approximately half of patients with cirrhosis and it may be improved by beta-blockers. ...T …

Sympathoexcitation increases the QT/RR slope in healthy men: differential effects of hypoxia, dobutamine, and phenylephrine.
Xhaët O, Argacha JF, Pathak A, Gujic M, Houssiere A, Najem B, Degaute JP, Van de Borne P. Xhaët O, et al. J Cardiovasc Electrophysiol. 2008 Feb;19(2):178-84. doi: 10.1111/j.1540-8167.2007.01039.x. Epub 2007 Dec 12. J Cardiovasc Electrophysiol. 2008. PMID: 18081764
The effects of changes in sympathetic and vagal activity on the QT/RR slope are controversial. We tested the hypothesis that sympathoexcitation is an important determinant of the QT/RR slope. ...Vagal cardiac activation by phenylephrine does not change the QT …

The effects of dobutamine and dopamine on intrapulmonary shunt and gas exchange in healthy humans.
Bryan TL, van Diepen S, Bhutani M, Shanks M, Welsh RC, Stickland MK. Bryan TL, et al. J Appl Physiol (1985). 2012 Aug 15;113(4):541-8. doi: 10.1152/japplphysiol.00404.2012. Epub 2012 Jun 14. J Appl Physiol (1985). 2012. PMID: 22700799 Free PMC article.
It is possible that, as with exercise, intrapulmonary shunts are recruited with increased cardiac output during dobutamine and/or dopamine infusion that may contribute to the observed increase in Qs/Qt. ...Both dobutamine and dopamine increased cardiac output …

Site-specific effects of dobutamine on cardiac conduction and refractoriness.
Ismail H, Gabriels JK, Chang D, Donnelly J, Kim BS, Epstein LM, Hentz R, Fishbein J, Huang X, Kowalski M, Dasrat P, Rahyab AS, Goldner B. Ismail H, et al. J Interv Card Electrophysiol. 2024 Jan;67(1):71-82. doi: 10.1007/s10840-023-01573-1. Epub 2023 May 25. J Interv Card Electrophysiol. 2024. PMID: 37227538
CONCLUSION: In this study, there was no statistically significant change of AVNBCL and VABCL relative to SCL from baseline to any dose level of dobutamine. As expected, the AH and QT intervals, and the VABCL, VERP, AERP and AVNERP all significantly decreased from ba …

Diastolic and autonomic dysfunction in early cirrhosis: a dobutamine stress study.
Dahl EK, Møller S, Kjær A, Petersen CL, Bendtsen F, Krag A. Dahl EK, et al. Scand J Gastroenterol. 2014 Mar;49(3):362-72. doi: 10.3109/00365521.2013.867359. Epub 2013 Dec 16. Scand J Gastroenterol. 2014. PMID: 24329122 Clinical Trial.

However, time to resume HR of 100 beats/min was significantly longer in cirrhosis, p < 0.01. The QTc interval increased after dobutamine infusion in cirrhosis (0.41 0.02 vs. 0.43 0.02 s, p = 0.001) but similar electrophysiological changes were seen in controls. ...Howev

Dobutamine infusion for unmasking long QT syndrome and torsades de pointes.
Quan F, Peng G, Kangan C, Dayi H, Cuilan L, Richard CC. Quan F, et al. Clin Cardiol. 2009 Jun;32(6):E79-82. doi: 10.1002/clc.20248. Clin Cardiol. 2009. PMID: 19353679 Free PMC article.
Prolonged QT interval is usually seen on routine electrocardiogram (ECG), but in some patients it may only be seen immediately before the evolution of torsades de pointes (Tdp). ...Torsades de pointes occurred 5 d later when the patient received an implantabl …
