Implantable Cardioverter Defibrillators and their Role in Cardiovascular Disease

Abstract

Fatma Karadeniz*

Cardiovascular disease remains a leading cause of mortality worldwide. Implantable cardioverter defibrillators have become a crucial component of managing certain high-risk CVD patients, primarily those with a history of ventricular arrhythmias or cardiac arrest. However, despite advances in technology and the life-saving potential of ICDs, not all patients derive the same benefit from these devices. Recent research has suggested that nighttime heart rate, a previously underexplored parameter, may have prognostic significance in patients with ICDs. This article delves into the association between nighttime heart rate and cardiovascular mortality in patients with ICDs, exploring the potential implications for risk stratification and patient management. ICDs are specialized devices designed to treat life-threatening ventricular arrhythmias, particularly ventricular tachycardia and ventricular fibrillation.
