BACKGROUND Intramural septal idiopathic ventricular arrhythmias have not been described systematically. METHODS AND RESULTS In a consecutive group of 93 patients with idiopathic ventricular arrhythmias referred for ablation, the site of origin of ventricular arrhythmias was assessed by activation mapping and pace-mapping. In 7 of 93 patients (8%), an intramural focus in the interventricular s...

AIMS To describe the frequency and type of arrhythmia induced by forced expiratory and inspiratory flow-volume loop manoeuvres. METHODS 735 subjects (548 men) aged from 10 to 98 years old (mean 54 years, SD +/- 15) were submitted to a conventional medical examination and spirometry testing prior to a maximal cardiopulmonary exercise test (CPET). A continuous digital electrocardiogram (ECG) wa...

A severe case of flecainide-induced incessant ventricular arrhythmias is presented. These arrhythmias were resistant to various intravenous antiarrhythmic drugs and to cardiac pacing. Intravenous amiodarone administered over a short period and in a high dose strikingly abolished all ventricular arrhythmias.

Atrial arrhythmias are being increasingly recognized in inherited arrhythmogenic disorders particularly in patients with Brugada syndrome and short QT syndrome. Atrial arrhythmias in inherited arrhythmogenic disorders have significant epidemiologic, clinical, and prognostic implications. There has been progress in the understanding of underlying genetic characteristics and the mechanistic link ...

BACKGROUND A comprehensive evaluation of postoperative arrhythmias following surgery for congenital heart disease by continuous Holter monitoring has not been carried out. We aimed, firstly, to establish the time course of pre- and early postoperative arrhythmias by beat-to-beat analysis following cardiopulmonary bypass and, secondly, to examine which surgical procedures present risk factors fo...

PURPOSE OF REVIEW To explore recent findings on the treatment and outcome of cardiac arrhythmias and how they affect ICU activities. RECENT FINDINGS The rate vs. rhythm control debate for the treatment of chronic atrial fibrillation continues. It is still unclear whether the postcardiac surgery inflammatory response contributes to the development of atrial fibrillation. In noncardiothoracic s...

objective: in ventricular arrhythmias, due to their free radical scavenging action, antioxidant agents are usually used in the treatment of cardiovascular disease. since stress is considered as risk factor for increased mortality by causing malignant arrhythmias, the study was designed to evaluate the cardioprotective effects of ellagic acid (ea) on cacl2-induced arrhythmias in rat stress model...

Aims Alcohol is a risk factor for cardiac arrhythmias. Retrospective analyses suggest supraventricular arrhythmias consecutive to acute alcohol consumption, but prospective data are limited. We intended to prospectively associate acute alcohol consumption with cardiac arrhythmias. Methods and results At the 2015 Munich Octoberfest, we enrolled 3028 voluntary participants who received a smartp...

objective(s):this study aimed to examine the hypothesis that an antiarrhythmic effect might be obtained by ischemic preconditioning of the liver, and also to characterize the potential underlying mechanisms. materials and methods: male wistar rats were anesthetized by thiopental sodium (50 mg/kg, ip) followed by iv injection of heparin (250 iu). remote ischemic preconditioning (ripc) was induce...

In patients without established cardiac disease, the occurrence of premature ventricular complexes without sustained ventricular tachycardia is more an annoyance than a medical risk, and treatment is not required. In contrast, patients with established heart disease and premature ventricular complexes have a higher likelihood of developing ventricular tachycardia or fibrillation. These patients...
