AIMS First-line ablation prior to antiarrhythmic drug (AAD) therapy is an option for symptomatic paroxysmal atrial fibrillation (PAF); however, the optimal ablation technique, radiofrequency (RF), or cryoballoon (CB) has to be determined. METHODS AND RESULTS The FREEZE Cohort Study compares RF and CB ablation. Treatment-naïve patients were documented in(More)
BACKGROUND Patients with idiopathic dilated cardiomyopathy (DCM) and impaired left ventricular ejection fraction have an increased risk of dying suddenly. METHODS AND RESULTS Patients with recent onset of DCM (< or =9 months) and an ejection fraction < or =30% were randomly assigned to the implantation of an implantable cardioverter-defibrillator (ICD) or(More)
Electromagnetic radiation may interact adversely with implanted pacing systems and implantable cardioverter-defibrillators (ICDs). 1–4 Modern life exposes us all to an ever increasing number of potential sources of electromagnetic interference (EMI) and patients with implanted pacemakers or ICDs often ask about the use of microwave ovens, walking through(More)
BACKGROUND Defibrillation thresholds (DFT) with standard implantable cardioverter-defibrillator leads in the right ventricle (RV) may be determined by weak shock field intensity in the myocardium of the left ventricle (LV). Adding a shocking electrode in a coronary vein on the middle of the LV free wall, thereby establishing biventricular defibrillation,(More)
BACKGROUND If intravenous access cannot be attained during resuscitation of adult patients, endotracheal application of at least 2 mg of adrenaline is recommended. However, the effects of this intervention have not yet been demonstrated in adults. OBJECTIVE To demonstrate the effects of adrenaline administered through the airways. DESIGN Prospective(More)
OBJECTIVES Five drug classes have been shown to improve the prognosis of acute myocardial infarction in clinical trials: aspirin, beta-blockers, statins, renin angiotensin system (RAS) blockers and thienopyridines. We aimed to assess whether the benefits of combining these drugs (termed optimal medical therapy, OMT), will result in a reduction of mortality(More)
INTRODUCTION An increasing number of genetically altered mice with specific molecular cardiac defects are being assessed by electrophysiological studies and ECG monitoring. This approach should allow for the identification of critical genes involved in the arrhythmogenesis in myocardial infarction. Therefore it was the aim of this study to establish a(More)
Appropriate and inappropriate therapies of implantable cardioverter defibrillators have a major impact on morbidity and quality of life in ICD recipients, but have not been systematically studied in children and young adults during long-term follow-up. ICD implantation was performed in 20 patients at the mean age of 16 +/- 6 years, 11 of which had prior(More)
INTRODUCTION Bidirectional conduction block at the subeustachian isthmus predicts long-term efficacy of atrial flutter ablation. Limited data are available on the incidence and outcome of minor conduction changes such as unidirectional or incomplete block. This prospective study sought to systematically assess discrete acute and long-term alterations of(More)
