BACKGROUND Permanent pacing is the therapy of choice for treating severe and/or symptomatic bradyarrhythmia. However, augmented life expectancy and increasing health care expenditures have led to questions concerning the routine use of electrotherapy in very elderly patients. This study is aimed at assessing data on the actual number, characteristics, and(More)
AIMS Onset and termination of atrial fibrillation are often associated with abrupt changes in heart rate. Presence and time-course of delayed adaptation of the QT/QTc interval are unknown, but a temporary "mismatch" between rate and the QT interval may enhance the risk of proarrhythmia. METHODS In a prospective two-part study, time-course of adaptation of(More)
The present generation of implantable cardioverter defibrillators (ICDs) provides a very effective device for monitoring and treating life-threatening ventricular tachyarrhythmia. Patients at risk of sudden cardiac death who are directed to this form of treatment usually have severe coronary artery disease, previous myocardial infarction, and low ejection(More)
There is increasing evidence for a fatal interaction of myocardial ischemia, ventricular arrhythmias and sudden cardiac death in some patients with coronary artery disease. Evidence comes from autopsy studies, from the evaluation of patients who survived an episode of sudden cardiac death, from follow-up data of these patients either treated or not by(More)
The study was designed to assess the beat-to-beat variation of ventricular repolarization in patients with myocardial ischemia, hear failure, and in normal subjects. Autonomic tone may alter the dynamic QT/RR interval relation and thus may be involved in ventricular arrhythmia development, especially in the diseased heart. The study included 145 patients(More)
Our report describes the late migration of an atrial screw-in lead into the right internal jugular vein causing subsequent subclinical thrombus formation at the tip of the electrode. Previously initiated anticoagulation for atrial fibrillation may have prevented complete occlusion of the internal jugular vein. Therefore, prophylactic anticoagulation should(More)
AIM In the presence of coronary artery disease, implantable cardioverter-defibrillators (ICD) are used effectively for treating life-threatening tachyarrhythmias. Continuous monitoring of myocardial ischaemia would provide a new diagnostic option in future ICD generations. METHODS AND RESULTS In 22 selected patients undergoing coronary angioplasty,(More)
Modern pacemaker therapy is considered to be a safe and reliable procedure in the treatment of symptomatic and/or prognostically important bradycardiac arrhythmias. About every sixth patient dies of sudden cardiac death in the period after pacemaker implantation, whereby death is in the vast majority of cases ascribable to progression of underlying cardiac(More)
BACKGROUND Series of discharges from an implanted defibrillator (ICD) to terminate life-threatening ventricular tachyarrhythmias are one particular aspect of energy use and success of ICD therapy. Little is known about prevalence. characteristics, and risk stratification of so-called "cluster arrhythmias." HYPOTHESIS The objective of this study was to(More)
