APPROACH AND MANAGEMENT OF SUDDEN DEATH RISK IN PATIENTS WITH COMPLEX VENTRICULAR ARRHYTHMIAS

Abstract

The implantable cardioverter-defibrillator (ICD) is a cornerstone in the prevention of sudden cardiac death in patients with complex ventricular arrhythmias. This study aimed to evaluate the effectiveness of ICDs in reducing mortality and the associated risk stratification strategies in patients at high risk of sudden cardiac death. A comprehensive review of the literature was conducted, focusing on the latest evidence from clinical trials and observational studies. The findings demonstrate that ICDs significantly improve survival rates in patients with a history of ventricular arrhythmias or those with underlying conditions predisposing them to sudden cardiac arrest. However, the decision to implant an ICD requires careful consideration of individual risk factors, including left ventricular ejection fraction, the presence of ischemic heart disease, and genetic predispositions. Additionally, the study discusses the complications related to ICD implantation, such as infection, lead displacement, and inappropriate shocks, highlighting the importance of ongoing follow-up and device management. The results underscore the critical role of ICDs in the management of patients with complex ventricular arrhythmias, while also calling attention to the need for personalized risk assessment and the management of potential complications.
