Author: Riccardo Fenici, Elisabetta Baldo, Maria Pia Ruggieri and Peter Fenici

Both acute and chronic forms of psychological stress have been proposed as precipitants of sudden cardiac death in patients with coronary artery disease. However few information has been gained so far, about the effects of acute psychological stress in pa...

Changes In Programmed Electrical Stimulation Results, Qt Interval Duration And Qt Interval Dispersion Following Ptca In Patients With Left Ventricular Hypertrophy

Author: Jyri Kaik MD, PhD, Jaan Eha MD, PhD et al.

The aim of the study was to evaluate the effect of successful PTCA on enhanced myocardial electrical instability, assessed by programmed ventricular stimulation (PES) and QT/QTc interval dispersion (QTD/QTcD) determination in 27 CAD patients (pts) with le...

Clinical competence in electrophysiological procedures

Author: Ronald W F Campbell, Richard Charles, et.al.

All aspects of health care are under intense scrutiny, none more so than the competence of health care professionals to diagnose and manage disease. Correctly, patients expect those who minister to them to be competent and properly trained. Concepts of wh...

Comparison of QT Dispersion Between Hypertrophic Cardiomyopathy and Hypertensive...

Author: Andrzej Lubinski, Anna Baczynska, Jacek Kubica, et.al.

Patients (pts) with idiopathic hypertrophic cardiomyopathy (HCM) are thought to be at increased risk of sudden cardiac death. Recently, QT dispersion has been suggested to reflect dispersion in cardiac repolarisation (DCR) which is responsible for occurre...

Evaluation Of Antiarrhythmic Effect Of Extended Transatrial Septal Approach In M...

Author: Dusan Velimirovic MD PhD , Predrag Petrovic MD PhD, et al.

The aim of the study was to analyze the effect of surgical moderation of conduction from the atrium to the atrio-ventricular (AV) node on ventricular rate control in 25 patients with chronic atrial fibrillation (AF) undergoing mitral valve replacement (MV...

Functional State of Sinus Node in Patients with Conduction Disturbances

Author: G.V. Matiouchine, V.A. Shulman, S.E. Golovenkin, B.V. Nazarov

It is well known that patients with sick sinus syndrome (SSS) may present associated atrioventricular (AV) and/or intraventricular (IV) conduction defects [1] [2] [3] [4]. On the other hand, the incidence of sinus node dysfunction (SND) pathogenetic and p...

Methods Of High Resolution Electrocardiography For Children At Risk Of Life-Thre...

Author: Gennady G. Ivanov, Maria.A. Shkolnikova, Tatiana T. Masterkova

The method of high resolution (or signal-averaged) electrocardiography (ECG HR) with analysis of the late ventricular potentials is one of the non invasive procedures for diagnosis. The purpose of the present study is to examine the facilities of high res...

Radiofrequency Ablation for Inappropriate Sinus Tachycardia Following Successful Ablation of Atrioventricular Nodal Reentrant Tachycardia

Author: Jamie B. Conti MD, Kelly J. Tucker MD, Mark H. Mines MD et al.

Inappropriate sinus tachycardia is an uncommon clinical problem that may be refractory to medical management. It has been described after radiofrequency ablation of other supraventricular tachycardias. We describe a case of successful ablation of inapprop...

Restoration And Maintenance Of Sinus Rhythm After Valvular Heart Surgery. Is It ...

Author: Andrzej Szyszka, M.D. Andrzej Szyszka, M.D.

There are several advantages of restoring sinus rhythm in patients with atrial fibrillation after successful heart valve surgery [1]. However, longterm arrhythmia, advanced atrial remodeling diminish the chance of restoring stable sinus rhythm in this gro...

Rupture of Left Ventricular Aneurysm Causing Sudden Death Late After Radiofrequency Ablation

Author: Robert M. Campbell, MD, J. Edward Hulse, MD , Steve Neuberge MD et al.

Radiofrequency ablation is a widely accepted and practiced treatment for many supraventricular and ventricular tachycardias in both adult and pediatric patients [1] [2] [3] [4]. Even the enthusiasm of reported high success rates is tempered by catheteriza...

Singular Value Decomposition Of Body Surface Potential Maps And Vulnerability To...

Author: Petr Stovicek, MD, Zdenek Drska MD et al.

To evaluate the predictive value of a new diagnostic technique for detection of arrhythmogenic substrate, the following patients populations were studied: 46 healthy subjects (mean age 4515 yrs) with normal 12 lead electrocardiogram, and no history of car...

Surgical Parasympathetic AV Node Denervation In a Canine Model: Anatomical and E...

Author: V. Sokolovas, R. Lekas, D. Pauza, J. Sakalauskas, K. Lukosevicius

The Atrioventricular node (AV node) plays an important role in the transmission of impulses from atria to ventricles. Sometimes it can perform the function of the accessory pacemaker. Due to disorders in its function arrhythmia can arise (AV block, suprav...
