Incessant accelerated idioventricular rhythm mimicking preexcitation.

J Electrocardiol 2020 Jun 11;61:137-140. Epub 2020 Jun 11.

Arrhythmia Unit, Cardiology Department, Hospital La Luz - Quironsalud, Madrid, Spain.

ECG of patients with Wolf Parkinson White (WPW) syndrome may simulate other entities such as myocardial infarction, ventricular premature complexes, ventricular bigeminy, accelerated idioventricular rhythm, intermittent bundle branch block or electrical alternans. On the other hand, the opposite can also occur where these other conditions may simulate WPW. We present the case of a young patient referred for WPW ablation showing an incessant accelerated idioventricular rhythm mimicking preexcitation. Read More

Accelerated idioventricular rhythm resulting in torsades de pointes and cardiac arrest in a child: successfully cryoablated in left'coronary cusp.

Cardiol Young 2020 Mar 20;30(3):418-421. Epub 2019 Dec 20.

Pediatric Cardiology, Bursa Medicana Hospital, Bursa, Turkey.

Known as a benign arrhythmia and normally requiring no specific treatment, accelerated idioventricular rhythm can rarely degenerate to a life-threatening arrhythmia. Here, we present a child with left coronary cusp-originating accelerated idioventricular rhythm, degenerating into torsades de pointes and resulting in cardiac arrest, which was ablated with a cryocatheter. An 11-year-old boy, followed due to asymptomatic accelerated idioventricular rhythm before, was referred to our department because he had experienced an aborted cardiac arrest during sleep.

Prenatal diagnosis and prognosis of accelerated idioventricular rhythm.

Ultrasound Obstet Gynecol 2017 Nov;50(5):624-631

Fetal Cardiology Unit, Department of Pediatrics, CHU Sainte-Justine, University of Montreal, Québec, Canada.

Objectives: As postnatal identification of accelerated idioventricular rhythm (AIVR) relies on specific electrocardiographic patterns, prenatal diagnosis of this condition is challenging and its true incidence is unknown. The objectives of this study were to evaluate the performance of prenatal ultrasonography in identifying intrauterine cardiocirculatory events linked to specific electrocardiographic signs of postnatal AIVR, including left or right ventricular origin, and to assess the prenatal prognosis of this arrhythmia.

Methods: We reviewed Doppler tracings from the superior vena cava/ascending aorta (SVC/Ao), ductus venosus (DV), ductus arteriosus (DA) and aortic isthmus (AoI), as well as simultaneous M-mode recordings of septal and left ventricular wall motions of fetuses diagnosed with AIVR from January 2004 to December 2014.

Arrhythmias Seen in Baseline 24-Hour Holter ECG Recordings in Healthy Normal Volunteers During Phase 1 Clinical Trials.

J Clin Pharmacol 2016 07 11;56(7):885-93. Epub 2016 Jan 11.

Quintiles Cardiac Safety Services, Mumbai, India.

Regulatory agencies encourage sponsors to submit 24-hour ambulatory ECG data for assessing cardiac safety of new drugs, and some arrhythmias, hitherto considered rare, have been observed in some early-phase studies. Interpretation of these observations is difficult given the dearth of published data on the prevalence of cardiac arrhythmias seen during 24-hour continuous ECG monitoring in healthy volunteers (HV) from clinical trials. We analyzed drug-free ambulatory ECG recordings from 1273 HV (1000 males, 273 females; age 18-65 years) from 22 phase 1 studies that were analyzed in a core ECG laboratory; all subjects had normal screening ECGs.

Abnormal rhythms in patients without known cardiac disease after a first dose of fingolimod.

Mult Scler Relat Disord 2014 May 28;3(3):408-12. Epub 2013 Nov 28.

The Section of Cardiology, The Department of Medicine, Baylor College of Medicine, One Baylor Plaza, Houston, TX 77030, USA. Electronic address:

Background: Fingolimod is used to reduce the rates of relapse and slow the progression of disability in relapsing-remitting multiple sclerosis (RRMS). In-office monitoring of patients for 6h after the first dose of fingolimod is currently recommended due to rare cardiac rhythm disturbances. The objective of this paper is to describe our experience with continuous electrocardiographic monitoring of patients with RRMS starting on fingolimod. Read More

Postconditioning attenuates early ventricular arrhythmias in patients with high-risk ST-segment elevation myocardial infarction.

J Cardiol 2015 Jun 29;65(6):459-65. Epub 2015 Mar 29.

1st Department of Cardiology, University of Medical Sciences, Poznan, Poland.

Background: It has been demonstrated that postconditioning (postcon), brief episodes of ischemia during reperfusion period, in patients with ST-segment elevation myocardial infarction (STEMI) confers protection against ischemia-reperfusion injury and as a result, postcon might reduce infarct size. However, whether postcon may exert its beneficial effect on STEMI patients by reducing the occurrence of early malignant ventricular arrhythmias (VA) is still unknown. The aim of the study was to evaluate the influence of postcon on the presence of VA in early presenters with high-risk STEMI treated with primary coronary intervention (PCI). Read More

Minerva Cardioangiol 2015 Apr 22;63(2):121-33. Epub 2015 Jan 22.

Department of Cardiology and Intensive Care Medicine, St. Vincenz-Hospital, Paderborn, Germany -

This review summarizes different types of arrhythmias in patients with acute coronary syndromes and provides an overview of the available therapeutic options for acute care and management of critical arrhythmias. The different therapeutic options are depending on the origin and type of arrhythmia. The main common dominant mechanisms are intramural re-entry in ischemia and triggered activity in reperfusion.

Ectopic automaticity induced in ventricular myocytes by transgenic overexpression of HCN2.

J Mol Cell Cardiol 2015 Mar 3;80:81-9. Epub 2015 Jan 3.

Department of Physiology, Kurume University School of Medicine, Kurume, Japan. Electronic address:

Hyperpolarization-activated cyclic nucleotide-gated channels (HCNs) are expressed in the ventricles of fetal hearts but are normally down-regulated as development progresses. In the hypertrophied heart, however, these channels are re-expressed and generate a hyperpolarization-activated, nonselective cation current (Ih), which evidence suggests may increase susceptibility to arrhythmia. To test this hypothesis, we generated and analyzed transgenic mice overexpressing HCN2 specifically in their hearts (HCN2-Tg). Read More

Accelerated idioventricular rhythm observed under total intravenous anesthesia using remifentanil, propofol, and rocuronium.

JA Clin Rep 2015 7;1(1):12. Epub 2015 Sep 7.

Department of Anesthesia, Osakafu Saiseikai Noe Hospital, Fruichi 1-3-25, Joto-ku, Osaka City, Osaka Japan.

Accelerated idioventricular rhythm (AIVR) during anesthesia has been described in several drug toxicity such as from cocaine, halothane, desflurane, and propofol. We present the case of a man who developed episodes of AIVR observed under total intravenous anesthesia (TIVA) using remifentanil, propofol, and rocuronium. AIVR during anesthesia was a benign phenomenon, and further examinations after surgery showed no structural heart disease and the daily occurrence of idioventricular arrhythmias. Read More

Transient post-reperfusion left bundle branch block and accelerated idioventricular rhythm with paradoxical QRS narrowing.

J Electrocardiol 2014 Sep-Oct;47(5):705-7. Epub 2014 May 6.

Christus St. Vincent Hospital, Santa Fe, NM; Department of Medicine University of New Mexico Albuquerque, NM.

Accelerated idioventricular rhythm (AIVR) commonly follows coronary reperfusion and has been called a "reperfusion arrhythmia". Transient left bundle branch block (LBBB) is only rarely seen after interventional reperfusion and is usually considered a procedural complication. We report herein electrocardiograms (ECGs) in a case of acute lateral myocardial infarction which demonstrate both post-perfusion AIVR and a simultaneous transient LBBB with fusion complexes causing paradoxical QRS narrowing.
