Class III Antiarrhythmic Effects of Dofetilide in Rabbit Atrial Myocardium.

Journal of cardiovascular pharmacology and therapeutics

Pallandi RT, Lovell NH, Campbell TJ.
PMID: 10684421
J Cardiovasc Pharmacol Ther. 1996 Jul;1(3):229-234. doi: 10.1053/jcpt.1996.0229.

BACKGROUND: Dofetilide is a new class III antiarrhythmic agent with demonstrated efficacy in ventricular and atrial tachyarrhythmias. We investigated its class III actions and their modulation by stimulation rate in rabbit atrial myocardium. METHODS AND RESULTS: Standard microelectrode techniques...

Concomitant Block of the Rapid (I(Kr)) and Slow (I(Ks)) Components of the Delayed Rectifier Potassium Current is Associated With Additional Drug Effects on Lengthening of Cardiac Repolarization.

Journal of cardiovascular pharmacology and therapeutics

Geelen P, Drolet B, Lessard E, Gilbert P, O'Hara GE, Turgeon J.
PMID: 10684535
J Cardiovasc Pharmacol Ther. 1999 Jul;4(3):143-150. doi: 10.1177/107424849900400303.

BACKGROUND: The delayed rectifier potassium current, which comprises both a rapid (I(Kr)) and as slow (I(Ks)) component, is a major outward current involved in repolarization of cardiac myocytes. I(Kr) is the target of most drugs that prolong repolarization, whereas...

Current and emerging antiarrhythmic drug therapy for ventricular tachycardia.

Cardiology and therapy

Williams ES, Viswanathan MN.
PMID: 25135287
Cardiol Ther. 2013 Jun;2(1):27-46. doi: 10.1007/s40119-013-0012-5. Epub 2013 Feb 20.

Ventricular arrhythmias, including ventricular fibrillation (VF) and sustained ventricular tachycardia (VT), are the principal causes of sudden cardiac death in patients with structural heart disease. While coronary artery disease is the predominant substrate associated with the development of VT,...

[Congestive heart failure and sudden cardiac death: Pharmacological and non pharmacological treatment strategies].

Zeitschrift fur Kardiologie

Schmitt C.
PMID: 27320526
Z Kardiol. 2000 Oct;89:55-9. doi: 10.1007/PL00022886.

Recent multicenter studies have shown that the implantable cardioverter defibrillator (ICD) is superior compared to antiarrhythmic agents after sudden cardiac death (SCD) in patients with congestive heart failure. Further ICD studies have to be performed for primary prevention of...

Safety of Inpatient Dofetilide Initiation per Cardiology Services: A Retrospective Review.

Journal of pharmacy practice

Cicirale C, Jackson J, Gothard D.
PMID: 33736527
J Pharm Pract. 2021 Mar 19;8971900211000212. doi: 10.1177/08971900211000212. Epub 2021 Mar 19.

INTRODUCTION: Dofetilide is an antiarrhythmic medication that has the potential to cause life threatening arrhythmias, such as Torsade de pointes. The 2014 ACC/AHA/HRS guidelines for the management of patients with atrial fibrillation state that patients need to meet certain...

Refractory Torsades de Pointes Due to Dofetilide Overdose.

Journal of investigative medicine high impact case reports

Crosby J, Bhopalwala H, Kharawala A, Dewaswala N, Ganti SS, Bhopalwala A.
PMID: 34894807
J Investig Med High Impact Case Rep. 2021 Jan-Dec;9:23247096211056492. doi: 10.1177/23247096211056492.

Dofetilide, a class III antiarrhythmic, is widely used in the treatment of cardiac arrhythmias. Antiarrhythmic drugs can have a long duration of action that prolongs the QT interval. This causes bradycardia that predisposes to R-on-T phenomenon subsequently leading to...

Outpatient initiation of dofetilide: insights from the complexities of atrial fibrillation management during the COVID-19 lockdown.

Journal of interventional cardiac electrophysiology : an international journal of arrhythmias and pacing

Mascarenhas DAN, Mudumbi PC, Kantharia BK.
PMID: 33484394
J Interv Card Electrophysiol. 2021 Jan 23; doi: 10.1007/s10840-021-00942-y. Epub 2021 Jan 23.

BACKGROUND: At peak COVID-19 lockdown, patients with symptomatic atrial fibrillation (AF) were faced with an equipoise between a palliative rate-control versus cautious rhythm-control strategy, including hospitalization for initiation of antiarrhythmic drug/s (AADs) and cardiac procedures which was impossible due...

HiPSC-CMs from different sex and ethnic origin donors exhibit qualitatively different responses to several classes of pharmacological challenges.

Journal of pharmacological and toxicological methods

Zeng H, Wang J, Clouse H, Lagrutta A, Sannajust F.
PMID: 31201864
J Pharmacol Toxicol Methods. 2019 Sep - Oct;99:106598. doi: 10.1016/j.vascn.2019.106598. Epub 2019 Jun 12.

We investigated whether human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) created from diverse origins could have qualitatively (not just quantitatively) different responses to pharmacological reagents. Specifically, we challenged six hiPSC-CM syncytia made from a female Caucasian, a female black...

Frontiers in pharmacology

Diness JG, Abildgaard L, Bomholtz SH, Skarsfeldt MA, Edvardsson N, Sørensen US, Grunnet M, Bentzen BH.
PMID: 32508659
Front Pharmacol. 2020 May 20;11:749. doi: 10.3389/fphar.2020.00749. eCollection 2020.

BACKGROUND: Hypokalemia reduces the cardiac repolarization reserve. This prolongs the QT-interval and increases the risk of ventricular arrhythmia; a risk that is exacerbated by administration of classical class 3 anti-arrhythmic agents.Small conductance CaPURPOSE: To study the effects of pharmacological...

The Use of Intravenous Lidocaine in the Setting of Chronic Dofetilide Overdose: A Case Report.

Journal of pharmacy practice

Zhu E, Gabriele M, Nguyen MT.
