[ESC guideline 2022: management of ventricular arrhythmias in clinical practice].

The recently published guideline of the European Society of Cardiology for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death updates the guideline from 2015. Overall, the current guideline is characterised by a great practical relevance: Illustrative algorithms, e.g., for diagnostic evaluation, and tables make the guideline a user-friendly reference book. In the diagnostic evaluation and risk stratification of sudden cardiac death, cardiac magnetic resonance imaging and genetic testing are significantly upgraded. In long-term management, the optimal treatment of the underlying disease is essential, and recommendations for heart failure therapy are adapted to current international guidelines. Catheter ablation is upgraded especially for patients with ischaemic cardiomyopathy and recurrent ventricular tachycardia, as well as in the management of symptomatic idiopathic ventricular arrhythmias. Criteria for primary prophylactic defibrillator therapy remain controversial. In the context of dilated cardiomyopathy, imaging, genetic testing, and clinical factors are given special weight in addition to left ventricular function. Additionally, revised diagnostic criteria for a large number of primary electrical diseases are provided.
