Out of hospital cardiac arrest (OHCA) requiring cardio-pulmonary resuscitation (CPR) remains a mojor public health concern. OHCA affects nearly 275 000 people in Europe annualy with more than 70 000 of those in Germany alone. It represents of the major causes of death in Europe.In 40 % of patients CPR is successful and leads to a return of spontaneous circulation (ROSC). Due to the relevance of OHCA and CPR detailed guidelines with sound scientific foundation exist. However, even after successful CPR, mortality and morbidity remain high due to the severity of underlying diseases and sequelae of OHCA and CPR itself. Thus, optimization of the initial CPR treatment with reducing overall no-flow time (time from collaps with cardiac arrest to start of CPR) and optimization and streamlining of treatment algorithms and quality in hospitals receiving patients after cardiac arrest have been a strong focus to improve overall survival. Current guidelines suggest creation of Cardiac Arrest Centers as specialized hospitals who focus on high quality of post-resuscitation care with standardized processes and interdisciplinary treatment of patients after OHCA to establish fast, secure and effective treatment that is widely available in all regions.This article will address the relevant items to be considered in daily practice of resuscitation and post-resuscitation care for cardiac arrest. © Georg Thieme Verlag KG Stuttgart · New York.in English, German ANAMNESE UND KLINISCHER BEFUND  Eine 66-jährige Patientin mit chronischer HBV-Infektion unter antiviraler Therapie stellte sich mit Ikterus und allgemeiner Schwäche 2 Wochen nach einem Infekt der oberen Atemwege vor. Die Therapie setzte die Patientin 6 Monate vor Vorstellung eigenständig ab. Die Leber war leicht vergrößert tastbar, das Abdomen sowie der weitere körperliche Untersuchungsstatus waren unauffällig. UNTERSUCHUNGEN UND DIAGNOSE  Das Labor zeigte deutlich erhöhte Lebertransaminasen sowie ein erhöhtes Bilirubin. Der Hepatitis-B-Infektionsstatus bestätigte das Bild des chronisch-aktiven Verlaufs (HBsAg positiv), die Virusquantifizierung ergab Werte > 21 Mio. IU/ml. Sonografisch zeigten sich keine Auffälligkeiten. THERAPIE UND VERLAUF  Die antivirale Therapie wurde wieder aufgenommen mit nachfolgender Besserung der Lebertransaminasen und Abfall der Virusmenge. Nach 22 Wochen Behandlung traten eine Serokonversion (HBsAg negativ) und Ausheilung der Hepatitis ein. FOLGERUNG  Im Rahmen eines akuten Schubs einer chronischen Hepatitis B nach Beendigung der antiviralen Therapie ist eine Ausheilung mit Verlust des HBsAg möglich.Rhythm control therapy, comprising antiarrhythmic drugs, cardioversion, and AF ablation, is an important component in the management of patients with atrial fibrillation (AF). Catheter ablation for AF, mainly targeting isolation of the pulmonary veins (AF ablation), has markedly improved the effectiveness of rhythm control therapy. Rhythm control improves symptoms and quality of life in patients with symptomatic AF. AF ablation maintains sinus rhythm more effectively than antiarrhythmic drug therapy. Antiarrhythmic drugs remain effective after AF ablation, underpinning the synergistic mechanisms of action of AF ablation and antiarrhythmic drugs. Different lifestyle interventions might additionally improve symptoms and rhythm stability in patients with AF. AF ablation appears to improve left ventricular function in a subset of patients. Summarized, rhythm control therapy in patients with symptomatic AF is safe and improves quality of life, including elderly patients with stroke risk factors. cis-diamminedichloroplatinum II Further studies are needed to determine whether rhythm control therapy reduces AF-related complications while improving patient outcome with regard to prognosis. © Georg Thieme Verlag KG Stuttgart · New York.The assessment of the QT interval has been an integral part of ECG interpretation since the first descriptions of long QT syndrome by Wolff in 1950 and by Jervell and Lange-Nielsen in 1957. The correct measurement of the QT interval as well as a correct interpretation of the causes and of the clinical consequences of a QT prolongation, however, may be difficult even for trained internists and cardiologists. In this review, we give an overview on physiological determinants of cardiac repolarization, its marker in the surface ECG - the QT interval -, methods to correctly assess QT interval duration, causes for pathologically prolonged QT intervals, and resulting clinical consequences. A correct measurement of the QT interval should be performed by using the "tangent method", excluding possible U waves. A heart rate correction formula should be employed to determine the heart rate corrected QT interval (QTc).Many factors, which may prolong the QT interval, should be checked whenever a QTc prolongation is observed. These include drugs, electrolyte imbalances, hormonal influence, and comorbidities. The correct management of a patient with (genetically determined) LQTS starts with a risk stratification based on genotype, ECG phenotype, clinical history, age, sex, concomitant diseases, drug therapies, and family history for syncope or sudden cardiac death. The therapeutic approaches for LQTS are multimodal. Prevention is the basis of the therapy and includes avoiding known risk factors / and potentially QT-prolonging drugs, and a pharmacological treatment with non-selective beta blockers. According to the risk profile and to the patient's lifestyle the implantation of an ICD or a pacemaker should be considered. © Georg Thieme Verlag KG Stuttgart · New York.The use of medical antiarrhythmic therapy apart from beta-blockers has been steadily decreasing in the recent past. This can partly be attributed to technological progress that has rendered the ablation of complex cardiac arrhythmias like atrial fibrillation, focal atrial tachycardias and ventricular arrhythmias feasible and efficacious. Furthermore, an awareness regarding pro-arrhythmic and toxic side-effects of antiarrhythmic medication has evolved. Nevertheless, medical antiarrhythmic therapy still plays a fundamental role in acute therapy of arrythmias as well as certain indications for long-term therapy. This review comprehensively summarizes the current role of medical antiarrhythmic therapy in daily clinical practice focusing on mechanisms and therapies of the most common cardiac arrythmias. © Georg Thieme Verlag KG Stuttgart · New York.
