Pacemaker Failure following External Defibrillation
نویسنده
چکیده
Schematic diagram of an alternate possible mechanism in the Lown-Ganong-Levine syndrome. The impulse from the sinoatrial node (SAN) arrives either via the posterior internodal tract (PIT) or the normal tract to the atrioventricular node (AVN) at a His-Purkinje junction (LAMBDA) distal to the recording site of the His electrode. Retrograde depolarization of the proximal, and antegrade depolarization of the distal His-Purkinje system may therefore occur, producing an unusually shortened H-V interval.

Effects of compression depth and pre-shock pauses predict defibrillation failure during cardiac arrest.
BACKGROUND Cardiopulmonary resuscitation (CPR) and electrical defibrillation are the primary treatment options for ventricular fibrillation (VF). While recent studies have shown that providing CPR prior to defibrillation may improve outcomes, the effects of CPR quality remain unclear. Specifically, the clinical effects of compression depth and pauses in chest compression prior to defibrillation...
متن کاملPacemaker failure following external defibrillation.
T HE ENCLOSED tracings were recorded from a patient with transvenous Medtronic Demand Pacemaker Model 5841 no. 9K00824 after d-c shocks at 400 w-sec administered for ventricular fibrillation. The beginning of ventricular fibrillation is shown on strip A. The first and second d-c shocks did not abolish the fibrillation. The third d-c shock transiently abolished ventricular fibrillation, and irre...
متن کاملExternal cardiac pacing using low impedance electrodes suitable for defibrillation: a comparative blinded study.
OBJECTIVES The objective of this study was to determine whether the threshold for successful cardiac pacing is affected by electrode impedance and whether this procedure can be successfully carried out through low impedance electrodes that are also suitable for defibrillation. BACKGROUND Reintroduced in the early 1980s, external cardiac pacing utilizes large externally placed electrodes with ...
متن کاملCardiac Pacemaker Battery Discharge After External Electrical Cardioversion for Broad QRS Complex Tachycardia
External electrical cardioversion or defibrillation may be necessary in patients with implanted cardiac pacemaker (PM) or implantable cardioverter defibrillator (ICD). Sudden discharge of high electrical energy employed in direct current (DC) transthoracic countershock may damage the PM/ICD system resulting in a series of possible device malfunctions. For this reason, when defibrillation or car...
