An animal model for testing automatic defibrillators.

چکیده
A promising therapy for ventricular fibrillation--a life-threatening cardiac arrhythmia--is implantation of an automatic defibrillator. A critical component of such a device is the system that detects the presence of ventricular fibrillation. Automatic systems for detecting ventricular fibrillation have been tested with arrhythmias produced by electric shocks in normal canine hearts, but have not been tested with spontaneous arrhythmias in hyperirritable hearts. We have developed an animal model to create arrhythmias without electrical stimulation and have used it to test our automatic defibrillator. This model permits evaluation of both reliability to diagnose VF and reliability to reject other tachyarrhythmias.

An automatic test case generator for evaluating implementation of access control policies
One of the main requirements for providing software security is the enforcement of access control policies which aim to protect resources of the system against unauthorized accesses. Any error in the implementation of such policies may lead to undesirable outcomes. For testing the implementation of access control policies, it is preferred to use automated methods which are faster and more relia...
متن کاملDoes Microvolt T-Wave Alternans Testing Predict Ventricular Tachyarrhythmias in Patients With Ischemic Cardiomyopathy and Prophylactic Defibrillators?
Methods This prospective trial was conducted at 50 U.S. centers. Patients were eligible if they met MADIT-II (Multicenter Automatic Defibrillator Implantation Trial II) indications for device implant. All patients underwent MTWA testing followed by ICD implantation, with pre-specified programming to minimize the likelihood of therapies for non–life-threatening VTE. Minimum follow-up was 2 years...

متن کاملBRIEF REVIEW Approaches to modern management of cardiac arrest
Public access defibrillation The time delay to defibrillation can be reduced by five minutes if performed by a first responder to the cardiac arrest rather than by the usual paramedic service. In a review of five controlled trials in which emergency medical technicians were taught to defibrillate, odds ratios for improved survival ranged from 3.3 to 6.9. Emergency medical technicians were taugh...
