A Figure Of Merit For Evaluation and Comparison Of ICD Sensing Algorithm Performance

Author: Kelly H. McClure, Gabriel A. Mouchawar

Rate sensing in an ICD is used to deliver or withhold therapy. A standard method is needed for the evaluation of sensing algorithm performance. We composed 52 ventricular arrhythmia scenarios from patient data in the Ann Arbor Electrogram Library. The...

Atrial Oversensing in a Dual Chamber Implantable Cardioverter-Defibrillator due ...

Author: Todd J. Cohen, MD, Bassiema Ibrahim MD, et.al.

Recently, dual chamber implantable cardioverter-defibrillators have been approved by the United States Food and Drug Administration and released for the treatment of life-threatening ventricular tachyarrhythmias. These devices offer increased sensing and ...

Cerebral Autoregulation As A Major Determinant Of Tolerance To Ventricular Tachycardia In Patients With Implanted Cardioverter Defibrillator

Author: Igor Singer M.D. and Harvey L Edmonds Jr., Ph.D

Background. ICD therapy is based on the results of supine electrophysiologic (EP) testing. However, EP testing does not provide information about tolerance to ventricular tachycardia (VT) during upright posture. Transcranial Doppler (TCD) and cerebral ven...

Early and Late Surgical Complications in Subpectoral Implanted Cardioverter/Defibrillator-Systems (ICD): Experience in more than 100 Patients

Author: Ulrich F. Wolfhard, Fred H. Splittgerber, Michael Knocks et al.

Subpectoral (SP) implantation of ICD shells is now feasible in nearly all patients because of reduced case dimensions. The course of 101 patients who received a pectoral ICD system was compared with the course of patients who had the system implanted abdo...

Effect of Various Metal Areas with the Same Shadow Area on Defibrillation Electr...

Author: Bonner, Matthew; Mehra, Rahul.

The objective of this paper is to determine if the electrode resistance for defibrillation electrodes with the same shadow area changes with the exposed metal area. To accomplish this the electrode resistance was compared for identical coil electrodes wit...

Ipsilateral Implantation of ICD and Pacemaker

Author: Chetan P. Shah, MD, DM, Ranjan K. Thakur, MD, et.al.

The implantable cardioverter defibrillator (ICD) has dramatically changed the management of sudden cardiac death due to ventricular tachycardia (VT) or fibrillation. An estimated 15-20% of patients with an ICD also require cardiac pacing. The first genera...

Ischemic Skin Necrosis: A Complication of Implantable Cardioverter Defibrillator...

Author: Saihari Sadanandan, MD, Jonathan S Steinberg, MD, and Daniel Mark Siegel, MD

The Implantable cardioverter defibrillator (ICD) is widely used in the treatment of serious ventricular arrhythmias. A variety of complications of the ICD, including cutaneous lesions has been described. Ischemic skin necrosis due to the pressure of the I...

Life Threatening Ventricular Arrhythmias in Patients with Minimal or no Stuctural Heart Disease: Experience with the Implantable Cardioverter Defibrillator

Author: Emmanuel Manios, MD, Guilherme Fenelon, MD, Tibor Malacky et al.

Limited data exist about prognosis and appropriate treatment of life threatening ventricular arrhythmias in patients with no or minimal heart disease. In this study we report on a series of patients who suffered sudden cardiac death or syncope due to docu...

Local Anesthesia Versus General Anesthesia For Cardioverter / Defibrillator Implantation

Author: Günter Stix, MD , Anahit Anvari, MD, Thomas Pernerstorfer et al.

It has been shown recently that unipolar implantable cardioverter/defibrillators (ICD) can safely be implanted under local anesthesia (LA) with mild sedation only for defibrillation threshold (DFT) testing , and that the procedure is well tolerated. The a...

Stabilization and Resuscitation of Patients with Automatic Implantable Cardiover...

Author: John I. Ellis, MD

The AICD pulse generator is a computerized device that is usually implanted into the abdominal wall. Leads are placed on or in the heart to sense cardiac activity and to conduct the impulses from the pulse generator. The primary purpose of the AICD is to ...

Submuscular Pectoral Implantation of Cardioverter Defibrillators

Author: Andreas Markewitz, M.D., OFA, Hans Kaulbach, M.D et al.

Purpose of this paper is to review the experience with submuscular pectoral ICD implantation at two separate institutions, to describe the current surgical approach and to report the results obtained by this technique. From March 1993 until December 1995,...
