A Statistical Index for Early Diagnosis of Ventricular Arrhythmia from the Trend Analysis of ECG Phase-portraits [PDF]

open access: yesPhysiological Measurement, vol. 36, no. 1, pp. 107-131, January 2015, 2016
In this paper, we propose a novel statistical index for the early diagnosis of ventricular arrhythmia (VA) using the time delay phase-space reconstruction (PSR) technique, from the electrocardiogram (ECG) signal. Patients with two classes of fatal VA - with preceding ventricular premature beats (VPBs) and with no VPBs have been analysed using extensive

Antiarrhythmic Activity of Amino Acids Containing Nibentan Derivatives in Case of Symptoms of Occlusive and Reperfusion Arrhythmias

open access: yesРазработка и регистрация лекарственных средств, 2023
Introduction. Pharmacotherapy of cardiac arrhythmias is one of the urgent problems of modern medicine. The presence of serious side effects, in particular proarrhythmic action, limits the use of known antiarrhythmics in clinical practice.

Machine Learning-based Efficient Ventricular Tachycardia Detection Model of ECG Signal [PDF]

open access: yesarXiv, 2021
In primary diagnosis and analysis of heart defects, an ECG signal plays a significant role. This paper presents a model for the prediction of ventricular tachycardia arrhythmia using noise filtering, a unique set of ECG features, and a machine learning-based classifier model.

Clinical and molecular characterization of a cardiac ryanodine receptor founder mutation causing catecholaminergic polymorphic ventricular tachycardia [PDF]

open access: yes, 2015
Background Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a difficult-to-diagnose cause of sudden cardiac death (SCD). We identified a family of 1400 individuals with multiple cases of CPVT, including 36 SCDs during youth.

Anger and ventricular arrhythmias [PDF]

open access: yesCurrent Opinion in Cardiology, 2010
Although anecdotal evidence has long suggested links between emotion and ventricular arrhythmia, more recent studies have prospectively demonstrated the arrhythmogenic effects of anger, as well as mechanisms underlying these effects.Epidemiological studies reveal that psychological stress increases sudden death, as well as arrhythmias, in patients with

Ventricular arrhythmias following coronary artery bypass grafting for ischemic cardiomyopathy: When to insert an implanted cardioverter defibrillator?Central MessagePerspective

open access: yesJTCVS Open, 2023
Objectives: The study objectives were to determine the incidence, predictors, and clinical impact of ventricular arrhythmias after coronary artery bypass grafting and to evaluate the impact of implantable cardioverter defibrillators on the survival of ...

Attenuation of stretch-induced arrhythmias following chemical ablation of Purkinje fibres, in isolated rabbit hearts

open access: yesFrontiers in Physiology, 2023
Purkinje fibres (PFs) play an important role in some ventricular arrhythmias and acute ventricular stretch can evoke mechanically-induced arrhythmias. We tested whether Purkinje fibres, play a role in these arrhythmias.

A comparison of antiarrhythmic-drug therapy with implantable defibrillators in patients resuscitated from near-fatal ventricular arrhythmias.

open access: yesNew England Journal of Medicine, 1997
BACKGROUND Patients who survive life-threatening ventricular arrhythmias are at risk for recurrent arrhythmias. They can be treated with either an implantable cardioverter-defibrillator or antiarrhythmic drugs, but the relative efficacy of these two ...

Multiscale studies of delayed afterdepolarizations II: Calcium-overload-induced ventricular arrhythmias [PDF]

open access: yesarXiv, 2023
Disturbances in calcium homeostasis in a cardiac myocyte can lead to calcium-overload conditions and abnormal calcium releases, which occur primarily in the following two phases of the action potential (AP): (a) triggered or late calcium release (LCR) during the plateau phase; (b) spontaneous calcium release (SCR) during the diastolic interval (DI ...

Ventricular Arrhythmias in First Acute Myocardial Infarction: Epidemiology, Mechanisms, and Interventions in Large Animal Models

open access: yesFrontiers in Cardiovascular Medicine, 2019
Ventricular arrhythmia and subsequent sudden cardiac death (SCD) due to acute myocardial infarction (AMI) is one of the most frequent causes of death in humans.
