Patients who are on a waiting list for cardiac transplantation often have a clinical profile that satisfies current recommendations for the implantation of an implantable cardioverter-defibrillator for the primary prevention of sudden death. The prospect that transplantation may take place within the short-to-medium term puts the effectiveness of this therapy in doubt. We investigated the incid...

BACKGROUND Shock delivery of an implantable defibrillator may cause a change in the amplitude of endocardial electrograms and impair the detection of ventricular fibrillation. Thus, the effects of shock discharges on the amplitude of endocardial electrograms were evaluated in five patients undergoing implantation of a cardioverter-defibrillator in combination with a new nonthoracotomy lead syst...

The importance of early, uninterrupted chest compressions is emphasised throughout these guidelines. Much greater emphasis on minimising the duration of the preshock and post-shock pauses. The continuation of compressions during charging of the defibrillator is recommended. Immediate resumption of chest compressions following defibrillation is also emphasised; in combination with continuation o...

INTRODUCTION AND OBJECTIVES Implantable cardioverter-defibrillators reduce mortality in some patients with heart disease. Battery replacement is a frequent occurrence in clinical practice and is required in up to 30% of implants. The benefit/risk ratio of defibrillators varies over time and should be reevaluated at the time of replacement. The aim of this study was to determine the clinical cha...

A 46-year-old man with a history of sustained monomorphic ventricular tachycardia underwent an implantation of a third generation multiprogrammable implantable cardioverter defibrillator. One year post implant, while manipulating a remote control to a radiofrequency modulated toy car, the patient experienced a defibrillator discharge not preceded by an arrhythmia prodrome. Subsequent interrogat...

BACKGROUND There are limited data on the prognostic implications of brain natriuretic peptide (BNP) assessment in patients with mildly symptomatic heart failure (HF) who receive cardiac resynchronization therapy with a defibrillator (CRT-D). METHODS AND RESULTS The effect of elevated baseline and 1-year BNP levels (dichotomized at the upper tertile BNP of 120 pg/mL) on the risk of HF or death...

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...
