Defibrillation Threshold for Implantable Defibrillators
Background The time constant of truncated exponential pulses used with implantable defibrillators is determined by the output capacitor size and defibrillation pathway resistance. The optimal capacitor size is unknown. Methods and Results This study compared defibrillation threshold (DFT) for standard 120-,uF capacitors (DFT120) and smaller 60-,gF capacitors (DFT60) at implantation of cardiover...

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...
متن کاملImplantable Cardioverter Defibrillators
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...
متن کاملImplantable transvenous cardioverter-defibrillators.
BACKGROUND Implantable transvenous cardioverter-defibrillators offer a significant opportunity to decrease procedural morbidity and medical costs in the care of patients with life-threatening ventricular arrhythmias who otherwise would have required a sternotomy or thoracotomy for device insertion. The purpose of this study was to examine prospectively the safety, efficacy, and limitations asso...

N Engl J Med 2003;349:1836-47. Copyright © 2003 Massachusetts Medical Society. espite advances in emergency medical systems and in techniques of resuscitation, sudden death from cardiac arrest remains a major public health problem. Most persons who have an out-of-hospital cardiac arrest do not survive. 1,2 Those who are resuscitated may have severe, long-term cognitive impairment and motor impa...
