Diagnostik des Vorhofflimmerns und Beurteilung des Schlaganfallrisikos – Wie viel Vorhofflimmern ist zu viel Vorhofflimmern?

Vorhofflimmern ist definiert als eine Folge supraventrikulärer Extrasystolen von mehr als 30 Sekunden Dauer. Diese Definition ist arbiträr. Sie entspricht nicht dem tatsächlichen thromboembolischen Risiko, das durch Vorhofflimmern beeinflusst wird. Das Schlaganfallsrisiko bei Vorhofflimmern wird zum einen durch die Dauer, aber wesentlicher noch durch klinische Variablen bestimmt. Eine frühzeitige effektive Antikoagulation oder thromboembolische Präventionstherapie, wie sie auch durch den Vorhofohroccluder möglich ist, ist sinnvoll [24] [32] [34].

Atrial fibrillation is defined as a sequence of supraventricular extrasystoles of more than 30 seconds. This definition is arbitrarily. It does not correspond to the actual thromboembolic risk that is affected by atrial fibrillation. The risk of stroke in atrial fibrillation is essential determined by the duration of atrial fibrillation, but even more important by clinical variables. Early effective anticoagulation or thromboembolic prevention therapy (i.e. LAA occlusion) is useful.

Key words

Atrial fibrillation - stroke - anticoagulation
