The apicobasal dispersion of ventricular repolarization in humans is associated with age and affects arrhythmia vulnerability

The Journal of Physiology, EarlyView.
Abstract figure legend We investigated the age‐ and sex‐related differences in the apicobasal repolarization gradient (ABRG) and evaluated their possible role inventricular arrhythmia vulnerability. Electrocardiographic imaging (ECGI) was performed in healthy subjects during sinus rhythm, and the average recovery time (RT) and activation–recovery ...

Estudio de los mecanismos de las arritmias cardiacas mediante modelado y procesado robusto digital de señal [PDF]

, 2008
Las arritmias cardiacas son alteraciones del funcionamiento eléctrico normal del corazón. Algunas, las arritmias patológicas, son potencialmente malignas y constituyen una de las principales causas de mortalidad en el mundo occidental.

Evidence regarding clinical use of microvolt T-wave alternans [Accuracy of microvolt T-wave alternans testing]

, 2011
Background: Microvolt T-wave alternans (MTWA) testing in many studies has proven to be a highly accurate predictor of ventricular tachyarrhythmic events (VTEs) in patients with risk factors for sudden cardiac death (SCD) but without a prior history of ...

Effective cardiac resynchronization therapy for an adolescent patient with dilated cardiomyopathy seven years after mitral valve replacement and septal anterior ventricular exclusion

Journal of Cardiothoracic Surgery, 2010
Cardiac resynchronization therapy (CRT) is a new treatment for refractory heart failure. However, most heart failure patients treated with CRT are middle-aged or old patients with idiopathic or ischemic dilated cardiomyopathy.

Results of catheter ablation in patients with idiopathic premature ventricular contractions depending on the use of fluoroscopy

Российский кардиологический журнал, 2020
Premature ventricular contractions (PVC) is a very common type of arrhythmia. Some patients require surgical treatment. The search for the safest methods of surgical treatment is an important research task.Aim.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

Night syncope: a case report

Clinical Case Reports, 2017
Key Clinical Message “Idiopathic” ventricular fibrillations are rare and are estimated between 5% and 10% of survivors of hospital cardiac arrest, for at least some of them have as origin, a trigger in the Purkinje fibers. Interventional therapy could be

Longer action potential duration in the Purkinje network than in the ventricular myocardium delays retrograde activation of the human His‐Purkinje system

The Journal of Physiology, EarlyView.
Abstract figure legend Activation time (AT) maps from right ventricular apical pacing in a human ventricles model with longer action potential duration in the His‐Purkinje system (HPS) than in the myocardium (MYO). For pacing with a long S1S2 coupling interval (CI), the AT from the myocardial pacing site to the first AT of the HPS (ATMYO) is longer ...

Epidemiology of Arrhythmias in Children

Indian Pacing and Electrophysiology Journal, 2008
Unlike the adult population, arrhythmias occur less commonly in childhood. Only 5% of the emergency hospital admissions in the paediatric population is attributed to symptomatic arrhythmias.
