Long QT syndrome (LQT) represents a heterogeneous family of cardiac electrophysiologic disorders characterized by QT prolongation and T-wave abnormalities on the electrocardiogram. It is commonly associated with syncope, however, sudden cardiac death can occur due to torsades de pointes. LQT is a clinical diagnosis and should be suspected in individuals on the basis of clinical presentation, family history and electrocardiogram characteristics. Management is focused on the prevention of syncope and ultimately sudden death...

To compare outcome results from different institutions in a registry, it is necessary to have a way to take into account differences in the risk characteristics of the patients. This model has been constructed for the Implantable Cardioverter Defibrillator (ICD) Registry, and the most important variables have been identified. In another study, it has also been found that many of these patients have comorbidities, and the mortality rate 60 months after a replacement ICD was 41.2%. In a third study, it was determined that for individuals at least 65 years of age, 60 months after ICD placement, 50...

This article discusses 2 specialized implantable cardioverter defibrillator (ICD) devices. A special type of implantable device is available for cardiac resynchronization therapy, which can also have a defibrillator, in which case it is called a CRT-D device. In patients who meet guidelines for eligibility, a CRT-D will diminish the number of significant cardiac events including death. A subcutaneous ICD device does not need any leads placed in the vascular system and therefore does not have some of the complications that may be seen with transvenous ICDs...

Hypertrophic cardiomyopathy is the most common genetic cardiac disease. The most important pathophysiological finding is dynamic (outflow tract) obstruction of the left ventricle in about 70% of affected patients. Especially in younger patients, an increased risk of sudden cardiac death has been observed. Syncope and presyncope-in addition to extremely variable cardiac symptoms (dyspnea and angina)-are common. The etiology of syncope is complex. The most important aspect for diagnosis is a detailed history regarding the accompanying circumstances of the syncope...

The subcutaneous implantable cardioverter-defibrillator (S-ICD®, Boston Scientific, Marlborough, MA, USA, previously Cameron Health, San Clemente, CA, USA) represents an important milestone in ICD therapy for prevention of sudden cardiac death (SCD). Since the introduction of the S‑ICD in 2010, the device has undergone further development. Based on the unique feature of an entirely extracardiac implantation, the S‑ICD is able to reduce the common perioperative and long-term complications of the usual endovascular implanted ICD systems...
