The Role of Electrical Pacemakers in the Treatment of Unexpected Cardiac Arrest.

چکیده
DURING THE PAST 8 YEARS cardiac pacemakers have found an important use in the immediate and prolonged treatment of postoperative or spontaneously occurring heart block in which the idioventricular rate has become too slow to provide adequate cardiac output. Scarcely a major hospital in the country lacks one of these electronic devices. For the treatment of Stokes-Adams disease with heart block the role of pacemaker therapy is well established, but in other situations the popularity of pacemakers has sometimes outstripped their value. Ill-conceived efforts at cardiac stimulation can result in deaths either by direct injury or because the effort at pacemaking supplants more effective means of therapy. The commonest of these abuses have occurred in the treatment of patients with cardiac arrest. Some patients with cardiac arrest have been resuscitated with pacemaker therapy. This group of patients should serve as a guide in determining the limitations and indications for electrical stimulation in cardiac arrest. In virtually all successful cases the possibility of cardiac arrest was recognized in advance, either because of preexisting abnormalities such as heart block or because of capricious behavior of the heart under anesthesia. Because of the advance warning, the pacemaker was available at the patient's side and often the electrodes were in position on the chest. When arrest occurred, stimulation was immediately performed. Pacemaking warranted a trial under these circumstances both because this is

A Study of Cerebral Performance Categories Based on Initial Rhythm and Resuscitation Time Following In-Hospital Cardiac Arrest in a State Hospital in Turkey
Background: The cerebral performance category (CPC) score is widely used in research and quality assurance to assess neurologic outcome following cardiac arrest. However, little is known about the results of the CPC in Turkey. Objective: This study aimed to determine whether the CPC is associated with the initial rhythm and resuscitation time following re...
متن کاملErosive Pressure Dermatitis Associated with Cardiac Pacemaker
Erosive dermatitis is a skin reaction associated with implantable cardiac devices (ie, pacemakers and cardioverter defibrillators). We report a 65-year-old man with a history of several cerebrovascular attacks who developed an erythematous crusted erosive patch over the pacemaker site after implantation of two subsequent pacemakers. We suggest that physical irritation may be a trigger factor fo...
متن کاملA Case report of hemodynamic instability, cardiac arrest, and acute severe dyspnea subsequent to inhalation of crystal methamphetamine
Misuse of stimulants similar to amphetamine is a universal problem. These stimulants cause many complications in their abusers. However, myocardial infarction is rarely reported as a complication of amphetamine abuse. Herein, we report a man aged 42 years presented at the Emergency Department with the chief complaint of acute dyspnea following ice inhalation without history of dyspnea. Within t...
