BACKGROUND Current recommendations for anticoagulation management during cardioversion are largely based on historical data and expert consensus. METHODS AND RESULTS To characterize current practice of anticoagulation during and after elective cardioversion for AF and the risk of stroke and bleeding events, all patients enrolled into the Flec-SL trial(More)
OBJECTIVE To identify factors associated with short-term, intermediate and long-term outcome in patients with infective endocarditis (IE) and the need for treatment on intensive care unit (ICU). DESIGN AND SETTING Retrospective analysis and long-term follow-up by questionnaire in the two medical ICUs of our university hospital. PATIENTS We conducted a(More)
AIMS Atrial fibrillation (AF) is the most common cardiac arrhythmia. 'Silent', undiagnosed AF is often only detected with the first complication, e.g. a stroke. Detection of 'silent' AF prior to the first cerebrovascular event would be valuable to institute adequate therapy and prevent complications related to AF. We performed a simple electrocardiography(More)
OBJECTIVE To report the long-term safety and efficacy data of a third generation drug eluting stent (DES) with biodegradable polymer in the complex patient population of diabetes mellitus after a follow-up period of 5 years. BACKGROUND After percutaneous coronary intervention patients with diabetes mellitus are under higher risk of death, restenosis and(More)
BACKGROUND We investigated whether multichannel ECG-recordings are useful to risk-stratify patients with congenital long-QT syndrome (LQTS) for risk of sudden cardiac death under optimized medical treatment. METHODS In 34 LQTS-patients (11 male; age 31±13 years, QTc 478±51ms; LQT1 n = 8, LQT2 n = 15) we performed a standard 12-channel ECG and a(More)

AIMS Clinical and electrocardiographic (ECG) presentation of patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) and idiopathic right ventricular outflow-tract tachycardia (RVOT) may be similar. The aim of the study was to assess the validity and utility of T-wave integral measurement as an ECG discriminator of patients with ARVC and RVOT(More)
Atrial fibrillation (AF) is the most common cardiac arrhythmia, with a projected number of 1 million affected subjects in Germany. Changes in age structure of the Western population allow for the assumption that the number of concerned people is going to be doubled, maybe tripled, by the year 2050. Large epidemiological investigations showed that AF leads(More)
BACKGROUND Antiarrhythmic drugs prolong the atrial action potential and refractory period, and thereby prevent recurrent atrial fibrillation after cardioversion. The atrial action potential normalises after 2-4 weeks of sinus rhythm, suggesting that antiarrhythmic drugs might not be needed beyond that period. Therefore, we investigated whether short-term(More)
Percutaneous coronary intervention of complex stenoses is becoming more and more of an alternative to coronary bypass surgery. Nevertheless, complications can occur and lead to the need for circulatory support and/or emergency surgery. Circulatory support devices like the intra-aortic balloon pump showed only low benefit in patients' outcome. Devices with(More)
