Multiple Arrhythmogenic Substrate for Tachycardia in a Patient with Frequent Palpitations [PDF]

open access: yes, 2005
We report a 26-year-old woman with frequent episodes of palpitation and dizziness. Resting electrocardiography showed no evidence of ventricular preexcitation.

Atrioventricular conduction abnormalities are associated with poor outcome following intermittent umbilical cord occlusions in fetal sheep

open access: yesActa Obstetricia et Gynecologica Scandinavica, EarlyView.
Continuous electrocardiographic monitoring of fetal sheep heart during intermittent umbilical cord occlusions gradually leading to severe metabolic acidemia revealed several fetal arrhythmias including atrioventricular block, ventricular tachycardia, and ventricular fibrillation that would have gone unnoticed with current fetal monitoring systems ...

Supraventricular and ventricular arrhythmias: interventional management

open access: yesMedicine, 2010
Cardiac electrophysiology is the subspeciality of cardiology dealing with heart rhythm disorders, particularly the investigation and management of bradyarrhythmias and tachyarrhythmias, syncope and the prevention of sudden cardiac death. Recent years have seen significant developments in our understanding of arrhythmias.

Electrocardiograms from different types of exercise in Eventing horses with and without cardiac signs

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Exercising arrhythmias can be clinically irrelevant or associated with poor performance, collapse and sudden cardiac death. Objectives To test if readable exercising ECGs can be recorded by grooms or riders and to describe arrhythmias in ECGs from different types of exercise in Eventing horses and investigate associations with type ...

Catheter Ablation of Tachyarrhythmias in Small Children [PDF]

open access: yes, 2005
An estimated 80,000-100,000 radiofrequency ablation (RFA) procedures are performed in the United States each year.1 Approximately 1% of these are performed on pediatric patients at centers that contribute data to the Pediatric Radiofrequency Registry.2 ...

Association of heart rate variability, exercise intensity and exercising arrhythmias with competition results in eventing horses

open access: yesEquine Veterinary Journal, EarlyView.
Abstract Background Exercising arrhythmias are common in horses participating in eventing competitions. Heart rate variability (HRV) and a specific measure of the degree of heart rate fluctuation (Detrended Fluctuation Analysis alpha1; DFA‐α1) are proposed as exercise intensity and fatigue markers.

Risk factors of supraventricular arrhythmia in adults with congenital heart disease [PDF]

open access: yes, 2009
Background: Supraventricular arrhythmia (SVA) is a frequent clinical complication in adult patients with congenital heart disease (CHD). The aim of this study is prognostic evaluation of congenital heart defect complexity, performed cardiac surgery ...

Safety and Efficacy of a Novel Sealant‐Based Vascular Closure Device Following Electrophysiology Procedures: ReliaSeal Trial

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
In a clinical trial of a novel sealant‐based VCD to achieve hemostasis following endovascular procedures, patients randomized to receive the MYNX CONTROL VENOUS VCD had decreased TTH, TTA, and TDE, as compared to patients who received MC. ABSTRACT Background While manual compression (MC) remains the standard of care to achieve hemostasis, a novel ...

A retrospective study on the effects of illness severity and atrial fibrillation on outcomes in the intensive care unit [PDF]

open access: yes, 2013
Introduction: Atrial fibrillation (AF) is common in patients in the intensive care unit (ICU) and has been associated with worse outcomes. However, it is unclear whether AF itself adds to the risk of death or is merely a marker of illness severity ...

Supraventricular arrhythmias: investigation and treatment

open access: yesMedicine, 2006
Abstract Supraventricular arrhythmias (SVAs), with the exception of atrial fibrillation, are a group of rapid, regular tachycardias that use the atria and/or the atrioventricular (AV) node as part of their arrhythmia mechanism. This chapter examines the different electrophysiological mechanisms behind the most common SVAs. Atrial flutter is the result
