Expert consensus on acute management of ventricular arrhythmias - VT network Austria

The Arrhythmia Working Group of the Austrian Society of Cardiology (ÖKG) has set the goal of systematically structuring and organizing the acute care of patients with ventricular arrhythmias (VA), i.e. ventricular tachycardia (VT) or ventricular fibrillation (VF) in Austria. Within a consensus paper, national recommendations on the basic diagnostic work-up of VA (12-lead ECG, medical history, family history, laboratory analyses, echocardiography, search for reversible causes, ICD interrogation), as well as further medical treatment and therapeutic measures (indication of coronary angiography, ablation therapy) are established. Since acute ablation of VT is indicated in the current ESC guidelines as a class IB indication for scar-associated incessant VT or electrical storm (ES; ≥ 3 ICD therapies in 24 h) as well as for ischemic cardiomyopathy (iCMP) with recurrent ICD shocks, organizational measures must be taken to ensure that these guidelines can be implemented. Therefore, a VT network will be established covering all areas in Austria, consisting of primary and secondary VT centers. Organizational aspects of an acute VT network are defined and should subsequently be implemented by the participating hospitals. All electrophysiologic centers in Austria that deal with VT ablation are to be integrated into the network in the medium-term. Centers that co-operate in the network are divided into primary and secondary VT centers according to predefined criteria.

The role of coagulation, fibrinogenolysis and fibrinolysis in the development of fluid and clotted cadaver plasma

Parameters for coagulation, fibrinogenolysis and fibrinolysis were measured in order to understand the formation of fluid or clotted cadaver plasma. All values found were distinctly elevated without significant differences between fluid and clotted material. The electrophoretic banding pattern of the fibrinogen and fibrin material also proved extensive coagulation and fibrinolysis in all cases. In vitro experiments in which similar electrophoretic banding patterns were obtained suggested that the development of fluid cadaver plasma depends on the activation of fibrinolysis prior to complete coagulation, and is enhanced by persistence of circulation as well as a physiological pH (7.4). In correspondence to post mortal time only an increase in elastase values was found.
