Automated vulnerability testing identifies patients with inadequate defibrillation safety margin.
BACKGROUND Implantable cardioverter-defibrillator system efficacy is tested at implant by induction of ventricular fibrillation (VF). Defibrillation safety margin can be assessed without VF induction using upper limit of vulnerability methods, but these methods have required manual determination of T-wave timing. METHODS AND RESULTS To test the feasibility of an inductionless system of implan...
متن کاملA prospective evaluation of two defibrillation safety margin techniques in patients with low defibrillation energy requirements.
INTRODUCTION In patients undergoing defibrillator implantation, an appropriate defibrillation safety margin has been considered to be either 10 J or an energy equal to the defibrillation energy requirement. However, a previous clinical report suggested that a larger safety margin may be required in patients with a low defibrillation energy requirement. Therefore, the purpose of this prospective...
متن کاملInductionless or limited shock testing is possible in most patients with implantable cardioverter- defibrillators/cardiac resynchronization therapy defibrillators: results of the multicenter ASSURE Study (Arrhythmia Single Shock Defibrillation Threshold Testing Versus Upper Limit of Vulnerability: Risk Reduction Evaluation With Implantable Cardioverter-Defibrillator Implantations).
BACKGROUND Implantable cardioverter-defibrillators and cardiac resynchronization therapy defibrillators have relied on multiple ventricular fibrillation (VF) induction/defibrillation tests at implantation to ensure that the device can reliably sense, detect, and convert VF. The ASSURE Study (Arrhythmia Single Shock Defibrillation Threshold Testing Versus Upper Limit of Vulnerability: Risk Reduc...
متن کاملVulnerability Detection in ActiveX Controls through Automated Fuzz Testing
Vulnerabilities in ActiveX controls are frequently used by attackers to compromise systems using the Microsoft Internet Explorer web browser. A programming or design flaw in an ActiveX control can allow arbitrary code execution as the result of viewing a specially-crafted web page. In this paper, we examine effective techniques for fuzz testing ActiveX controls, using the Dranzer tool developed...
متن کاملDefibrillation threshold testing fails to show clinical benefit during long-term follow-up of patients undergoing cardiac resynchronization therapy defibrillator implantation.
BACKGROUND The utility of defibrillation threshold testing in patients undergoing implantable cardioverter-defibrillator (ICD) implantation is controversial. Higher defibrillation thresholds have been noted in patients undergoing implantation of cardiac resynchronization therapy defibrillators (CRT-D). Since the risks and potential benefits of testing may be higher in this population, we sought...
