Sudden cardiac death (SCD) is an important cause of mortality. In this article, we review the definition, impact and underlying aetiology of SCD. Ventricular tachyarrhythmia accounts for the majority of SCDs and can be caused by various underlying heart diseases, the most frequent being ischaemic cardiomyopathy. The most effective ways to reduce the risk of SCD in ischaemic cardiomyopathy are the optimal prevention of recurrent coronary ischaemia and the use of an implantable cardioverter-defibrillator (ICD) in high-risk patients. We discuss current patient selection for ICD implantation and focus on the need for, and possibilities to improve, SCD risk stratification.

The most common reason for sudden cardiac death is ischaemic heart disease. Patients who survive cardiac arrest are at particularly high risk of recurrent ventricular arrhythmia and sudden cardiac death, and are candidates for secondary prevention defined as ‘therapies to reduce the risk of sudden cardiac death in patients who have already experienced an aborted cardiac arrest or life-threatening arrhythmias’. The mainstay therapy for secondary prevention of sudden cardiac death is implantation of an implantable cardioverter defibrillator. Furthermore, revascularization and optimal medical therapy for heart failure and concurrent cardiovascular diseases should be ensured.

Dilated cardiomyopathy (DCM) is a disease characterised as left ventricular (LV) or biventricular dilatation with impaired systolic function. Regardless of underlying cause patients with DCM have a propensity to ventricular arrhythmias and sudden cardiac death. Implantable Cardioverter Defibrillator (ICD) implantation for these patients results in significant reduction of sudden cardiac death [1-3]. ICD devices may be limited by right ventricle (RV) sensing dysfunction with low RV sensing amplitude. We present a clinical case of patient with DCM, implanted ICD and low R wave sensing on RV lead.

AbstractImplantable cardioverter-defibrillators effectively reduce the rate of sudden cardiac death in children. Significant efforts have been made to better characterise the indications for their placement, and over the past two decades there has been a shift in their use from secondary to primary prevention. Primary prevention includes placement in patients thought to be at high risk of sudden cardiac death before the patient experiences any event. Secondary prevention includes placement after a high-risk event including sustained ventricular tachycardia or resuscitated cardiac arrest. Although liberal device implantation may be appealing even in patients having marginal indications, studies have shown high rates of adverse effects including inappropriate device discharges and the need for re-intervention because of hardware malfunction. The indications for placement of an implantable cardioverter-defibrillator, whether for primary or secondary prevention of sudden cardiac death, vary based on cardiac pathology. This review will assist the provider in understanding the risks and benefits of device implantation in order to enhance the shared decision-making capacity of patients, families, and providers.

Work Up

Background: Main objective of the study is details work up of the patients of ventricular tachy-arrhythmias and to find out its association with any structural heart disease.Methods: This institution based observational study was conducted in patients of documented sustained VT (ventricular tachycardia) with consecutive 102 patients.Results: The mean age of the VT patients was 56.7 years and the number of male patients were 70 (69%). In our study, among 102 patients 45 patients were diabetic, 64 patients were hypertensive, 30 patients were current smoker, family history of heart disease was present in 25 patients and family history of SCD (sudden cardiac death) was present in 5 patients. Among the patients who presented with symptoms of ventricular tachy arrhythmia, 25 patients had EF (ejection fraction) above 40%, 36 had EF between 31 to 40% and only 2 had EF below 30%. CAG (coronary angiography) done in 98 patients and 16 had normal coronaries. 20, 16 and 46 patients had single, double and triple vessel disease respectively. 80 patients had coronary heart disease (78%), 20 patients among them had acute ischemic events and 60 had chronic ischemic disease. 12 patients didn’t have any structural heart disease.Conclusions: Ischemic heart disease, acute or chronic, is the most common causes of ventricular tachyarrhythmia. male sex, diabetes mellitus, hypertension, smoking, family history of heart diseases or sudden cardiac death being the risk factors of coronary artery disease are also predisposing factors of ventricular tachyarrhythmia.
