Risk of cardiac arrhythmias after electrical accident: a single-center study of 480 patients.

Clin Res Cardiol 2019 Feb 15. Epub 2019 Feb 15.

Semmelweis University Heart and Vascular Centre, Városmajor u. 68, Budapest, 1122, Hungary.

Objective: Patients with electrical injury are considered to be at high risk of cardiac arrhythmias. Due to the small number of studies, there is no widely accepted guideline regarding the risk assessment and management of arrhythmic complications after electrical accident (EA). Our retrospective observational study was designed to determine the prevalence of ECG abnormalities and cardiac arrhythmias after EA, to evaluate the predictive value of cardiac biomarkers for this condition and to assess in-hospital and 30-day mortality.

Radiofrequency catheter ablation for drug-refractory atrial tachyarrhythmias in a patient with catecholaminergic polymorphic ventricular tachycardia: A case report.

J Cardiol Cases 2019 Jan 6;19(1):36-39. Epub 2018 Dec 6.

Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama, Japan.

Patients with catecholaminergic polymorphic ventricular tachycardia (CPVT) frequently have atrial arrhythmias, such as atrial tachycardia (AT) and fibrillation (AF), in addition to the ventricular tachyarrhythmias. The development of AT/AF in patients with CPVT is associated with adverse outcomes, and its management is still challenging. A 43-year-old woman with CPVT underwent radiofrequency catheter ablation (RFCA) for drug-refractory AT/AF. Read More

Nonreentrant atrial tachycardia occurs independently of hypertrophic cardiomyopathy in RASopathy patients.

Am J Med Genet A 2018 Aug 28;176(8):1711-1722. Epub 2018 Jul 28.

Genetics Unit, MassGeneral Hospital for Children, Boston, Massachusetts.

Multifocal atrial tachycardia (MAT) has a well-known association with Costello syndrome, but is rarely described with related RAS/MAPK pathway disorders (RASopathies). We report 11 patients with RASopathies (Costello, Noonan, and Noonan syndrome with multiple lentigines [formerly LEOPARD syndrome]) and nonreentrant atrial tachycardias (MAT and ectopic atrial tachycardia) demonstrating overlap in cardiac arrhythmia phenotype. Similar overlap is seen in RASopathies with respect to skeletal, musculoskeletal and cutaneous abnormalities, dysmorphic facial features, and neurodevelopmental deficits. Read More

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.

Int J Cardiol 2016 Jan 30;203:855-7. Epub 2015 Oct 30.

Prof. Dr. Mazhar Osman Mental Health and Neurologic Disorders Training and Research Hospital Istanbul, Turkey.

Risperidone, an atypical antipsychotic drug, is one of the most frequently used atypical neuroleptic drugs for the treatment of symptoms of behavioral disorders seen in autism. Although various cardiovascular side effects have been reported with risperidone, to our knowledge, it has not yet been reported that it can also result in multifocal atrial tachycardia. Based on the case reported herein, our aim is to bring awareness that risperidone may cause multifocal atrial tachycardia. Read More

Effect of an electronic control device exposure on a methamphetamine-intoxicated animal model.

Acad Emerg Med 2010 Apr;17(4):436-43

Department of Physiology and Biophysics, University of Louisville, Louisville, KY, USA.

Objectives: Because of the prevalence of methamphetamine abuse worldwide, it is not uncommon for subjects in law enforcement encounters to be methamphetamine-intoxicated. Methamphetamine has been present in arrest-related death cases in which an electronic control device (ECD) was used. The primary purpose of this study was to determine the cardiac effects of an ECD in a methamphetamine intoxication model. Read More

A case with catecholaminergic polymorphic ventricular tachycardia unmasked after successful ablation of atrial tachycardias from pulmonary veins.

Pacing Clin Electrophysiol 2009 Nov 27;32(11):e21-4. Epub 2009 Aug 27.

Division of Cardiology, Yokohama Rosai Hospital, Yokohama, Japan.

Catecholaminergic polymorphic ventricular tachycardia (VT) is characterized by polymorphic VT during exercise, and the association of atrial fibrillation (AF) has been reported. However, the mechanism of AF in this disease and the relationship between VT and AF has been obscured. We described a 13-year-old girl who referred for catheter ablation of exercise-induced paroxysmal AF. Read More

Intravenous magnesium for cardiac arrhythmias: jack of all trades.

Authors:
Kwok-Ming Ho

Magnes Res 2008 Mar;21(1):65-8

Department of Intensive Care, Royal Perth Hospital, Perth, Australia.

Intravenous magnesium has been used to prevent and treat many different types of cardiac arrhythmia. It has diverse electrophysiological actions on the conduction system of the heart; including prolonging sinus node recovery time, and reducing automaticity, atrioventricular nodal conduction, antegrade and retrograde conduction over an accessory pathway, and His-ventricular conduction. Intravenous magnesium can also homogenise transmural ventricular repolarisation. Read More

Cardiac arrhythmias imprint specific signatures on Lorenz plots.

Ann Noninvasive Electrocardiol 2008 Jan;13(1):44-60

Division of Cardiology, School of Medicine, Otto-von-Guericke-University, Magdeburg, Germany.

Background: Despite the growing number of studies using Lorenz (Poincaré) plots (LPs) for the analysis of heart rate variability (HRV), a possible correlation between the underlying ECG waveforms and the RR scatter plots has never been systematically studied. We report a comprehensive investigation of distinct Lorenz plot patterns (LPPs) encountered in the context of major cardiac tachyarrhythmias as assessed by 24-hour Holter monitoring and detail the mechanisms underlying the specific LPPs.

Methods: The 24-hour ambulatory electrocardiograms (AECGs) of 2700 patients with atrial and/or ventricular tachyarrhythmias and the AECGs of 200 controls with pure sinus rhythm were analyzed using an Elatec arrhythmia analyzing system (Elamedical, Paris 1996). Read More

Further delineation of the phenotype resulting from BRAF or MEK1 germline mutations helps differentiate cardio-facio-cutaneous syndrome from Costello syndrome.

Am J Med Genet A 2007 Jul;143A(13):1472-80

Division of Medical Genetics, A.I. duPont Hospital for Children/Nemours Childrens' Clinic, Wilmington, DE 19899, USA.

Because Cardio-facio-cutaneous (CFC) syndrome has significant phenotypic overlap with Costello syndrome, it may be difficult to establish the diagnosis on a clinical basis. The recent discoveries of germline HRAS mutations in patients with Costello syndrome and mutations in BRAF, MEK1, and MEK2 in CFC syndrome uncovered the biologic mechanism for the shared phenotypic findings based on the close interaction of the affected gene products within the MAP kinase pathway. We evaluated a series of patients who were either clinically diagnosed with Costello syndrome, or in whom the diagnoses of both Costello and CFC syndromes were considered. Read More

[Lipomatous hypertrophy of the cardiac interatrial septum].

Cesk Patol 2006 Oct;42(4):182-5

Fingerlandův ústav patologie LF UK a FN, Hradec Králové.

Lipomatous hypertrophy of the interatrial septum (LHIS) is a rare lesion of unknown origin usually diagnosed as an incidental finding during autopsy. It can be associated with supraventricular arrhythmias, venous return obstruction and sudden cardiac death. Five necropsy cases (4 females, 1 male) of LHIS were encountered during the last 31 years; only one case from this series was diagnosed ante mortem. Read More

Systolic outward motion of the left ventricular apical wall as detected by magnetic resonance tagging in patients with apical hypertrophic cardiomyopathy.

J Cardiovasc Magn Reson 2006 ;8(3):453-60

Department of Cardiology, Akashi Municipal Hospital, Hyogo, Japan.

Patients with apical hypertrophic cardiomyopathy (APH) associated with paradoxic jet flow (ie, diastolic flow away from the apex) may gradually develop an apical aneurysm, which often leads to arrhythmia and mural thrombus formation. We observed systolic outward motion of the left ventricular apical myocardium in patients with APH using a magnetic resonance tagging procedure and examined the relationship of the outward motion to echocardiographic and scintigraphic findings and to cardiac events. Systolic displacement of the myocardial tags of the apical region perpendicular to the long axis in the 4-chamber view was recorded in 31 patients with APH. Read More
