Association of Long vs StandardDetection Intervals for Implantable Cardioverter-Defibrillators WithHospitalizations and Costs The roleof implantable cardioverter-defibrillators (ICDs) in reducing sudden and overall mortality is established.1 Recently, an ICD programming strategy that allows delayed detection of arrhythmiaswas shown to reduceunnecessary and inappropriate therapies.2,3 In this ex...

UNLABELLED Catecholaminergic polymorphic ventricular tachycardia (CPVT) is an electrophysiological disorder of a physically normal heart that occurs in children when the body is subjected to intense emotional or physical stress that causes adrenergic discharge. This troubling disease can be sporadic (spontaneous) or familial (genetic/inherited). Unfortunately, its associated ventricular tachyca...

udden cardiac death is a common problem, and increasing numbers of patients are surviving a first episode of a life threatening ventricular arrhythmia. In the absence of an acute myocardial infarction, patients who survive either ventricular fibrilla-tion or sustained ventricular tachycardia have a high risk of further episodes, which may be fatal. 1 Until recently, class I and class III antiar...

In recently years, Artificial Neural Networks have been studied extensively and applied in medical field, and have been demonstrated to have much better pattern recognition ability. In this chapter we present a VLSI chip to be implemented using 0.35 μm CMOS technology which is the implantable cardioverter defibrillator (ICDs). Implantable cardioverter defibrillator is a device which monitors th...

Electronic article surveillance (EAS) systems are widely implemented in public spaces and can adversely affect the performance of pacemakers and implantable cardioverter defibrillators. The interaction between implantable devices and EAS systems is a serious problem that can be minimized through appropriate facility design. Careful facility design and employee education along with patient vigil...

A 56 year old man with an implantable cardioverter defibrillator was admitted with chest pain and collapse. Erosion of the left ventricle by an epicardial patch was confirmed by thoracotomy, but surgical repair was impossible. This rare complication should be considered in patients with a history of cardioverter defibrillators implanted by thoracotomy.
