The ‘10 commandments’ for the 2022 ESC Guidelines for the management of patients with ventricular arrhythmias and the prevention of sudden cardiac death
Why the study?
Management of patients with ventricular arrhythmias and prevention of sudden cardiac death requires updated comprehensive guidance incorporating risk stratification, diagnostic evaluation, and treatment strategies.
Key Points
- To summarize the fundamental clinical principles and essential recommendations from the 2022 European Society of Cardiology guidelines for managing ventricular arrhythmias and preventing sudden cardiac death.
- Expert consensus and evidence synthesis conducted by the European Society of Cardiology guideline task force.
- Evaluation of diagnostic tools, autopsy protocols, risk calculators, genetic screening, and interventional strategies across inherited and acquired arrhythmogenic disorders.
- Multidisciplinary evaluation is advised for cardiac arrest survivors, and comprehensive autopsies are recommended for unexplained sudden deaths, particularly in individuals under 50 years of age.
- Indications for primary prevention implantable cardioverter defibrillators in dilated cardiomyopathy extend beyond left ventricular ejection fraction ≤35% through integration of cardiac magnetic resonance and genetics.
- Catheter ablation is recommended as first-line therapy for symptomatic idiopathic ventricular arrhythmias from the outflow tract or fascicles, arrhythmia-induced cardiomyopathy, and post-infarct recurrent ventricular tachycardia refractory to amiodarone.

Key expert perspectives
Captured external expert commentary on this paper, strongest first. Original sources are linked where available.
“The public is our major ally in the battle against sudden cardiac death in communities. Everyone, including schoolchildren, should learn how to do cardiopulmonary resuscitation (CPR) and use an AED. Both of these actions can save lives.”
“It's a very practical guideline, and I do think it will change the way that people do diagnosis of certain diseases, use imaging, [and apply] treatment modalities. Overall there's going to be less ICDs, not a lot, but some fewer ICD implantations, and I see that the general cardiologist really can use this.”
“Going one step further, emergency services should consider adopting mobile phone systems to locate and activate volunteers near to victims, allowing early resuscitation attempts before the arrival of paramedics.”

Abstract
Important points to remember (the ‘10 commandments’): The risk of VA/SCD increases with age. However, the age at presentation, the ‘age peak’ and the subtype of VA potentially leading to SCD, is different for different diseases (Figure 1). Survival rate remains low after out-of-hospital cardiac arrest. Early implementation of resuscitative interventions is pivotal to improve survival. It is important to increase the availability of public access defibrillators at sites where cardiac arrest is more likely to occur and to promote community training in basic life support, especially in schools. Sudden cardiac arrest survivors should undergo systematic examination overseen by a multidisciplinary team, to identify the cause of cardiac arrest and those at risk of an inherited cardiac disease that would warrant a familiar evaluation. Investigation of unexpected sudden death (SD) should be made a public health priority. A comprehensive autopsy is recommended, ideally, in all cases of unexpected SD, and always in those <50 years of age. Genetic testing is increasingly available. Risk stratification, including genetic findings, exists for several diseases and risk calculators have been developed (i.e. long QT syndrome (LQTS), lamin A/C cardiomyopathies). However, genetic and clinical testing should be undertaken only by multidisciplinary teams including professionals with skills to counsel on the implications and the uncertainty of results and experienced cardiologists able to direct testing. Risk prediction based on a single parameter does not consider the potential combined effect and interactions between factors. In patients with dilated cardiomyopathy/hypokinetic nondilated cardiomyopathy, indication for primary prevention implantable cardioverter defibrillator (ICD) implantation should not be restricted to an left ventricular ejection fraction (LVEF) ≤35%. The clinical presentation and results of additional tests (i.e. cardiac magnetic resonance imaging, genetic testing) are important to consider. Idiopathic premature ventricular contractions (PVCs) or VT are a diagnosis per exclusion. Cardiac magnetic resonance is important if initial evaluation is inconclusive or the presentation is atypical, and in patients with an unexplained reduced LVEF and a PVC burden of ≥10%. For symptomatic idiopathic PVC/VT from right ventricular outflow tract or left ventricular fascicle and for PVC-induced cardiomyopathy catheter ablation is first-line treatment. Catheter ablation is first-line treatment for recurrent VT in patients after myocardial infarction on amiodaron treatment. In patients with a preserved or mildly reduced LVEF after prior myocardial infarction presenting with a haemodynamically tolerated VT, either VT ablation performed in experienced centres or ICD implantation are treatment options requiring shared decision-making. Medical treatment has been specified for some diseases. Non-selective beta-blockers Nadolol or propranolol are the preferred beta-blockers in LQTS and catecholaminergic polymorphic ventricular tachycardia patients.
