Artificial cardiac pacing

Postgraduate Medicine, 1976
With increasing use of artificial cardiac pacing, criteria for selection of patients have been refined. In general, the most important indication for pacing is the presence and severity of symptoms due to bradyarrhythmias. Use of pacing in acute myocardial infarction remains controversial, but some guidelines are presented here.

Medical and physiological considerations in the use of artificial cardiac pacing. Part I

American Heart Journal, 1968
Abstract This review has been concerned with medical and physiological considerations in the clinical use of cardiac pacing. Certain problems were selected for discussion and the relevant pathology and pathophysiology treated in some depth. Particular attention was given to the Stokes-Adams syndrome, heart block complicating acute myocardial ...

Postcountershock pulseless rhythms: Response to CPR, artificial cardiac pacing, and adrenergic agonists

Annals of Emergency Medicine, 1986
Clinically, countershock of ventricular fibrillation (VF) may result in asystole or a pulseless rhythm in more than 50% of attempts. We conducted a study to assess the effects of immediate artificial pacing, CPR, and adrenergic drug therapy in the management of postcountershock pulseless rhythms. Thirty-four episodes of VF followed by countershock were

Sleeping Threshold Change Causing Failure of Artificial Cardiac Pacing

JAMA: The Journal of the American Medical Association, 1971
To the Editor.— Along with environmental, metabolic, and pharmacologic influences on artificial cardiac pacing, important threshold changes have been reported to occur incident to changes in physical activity. 1 Clinically evident interruption of pacing as the result of these influences has largely been reported as a result of drug administration. 2,3

Artificial Cardiac Pacing: Practical Approach

JAMA: The Journal of the American Medical Association, 1980
With more than a third of a million patients now carrying permanently implanted electronic pacemakers and with the lives of many of these patients absolutely dependent on that device, physicians now require at least rudimentary knowledge of their function.

Artificial Cardiac Pacing: A Practical Approach

Archives of Surgery, 1984
Gone are the halcyon days when a patient could have a syncopal episode, obtain a diagnosis of heart block, receive a comprehensible ventricular-demand pacemaker, thank you profusely, go home, and live happily ever after. Your tax dollar has sired a space program resplendent with sophisticated microprocessing and computerization that are readily ...

Abstract 4139637: Artificial Intelligence ECG Mapping of Biventricular Pacing QRS Morphology Predicts Response to Cardiac Resynchronization Therapy

Circulation
Background: Cardiac resynchronization therapy (CRT) is an important treatment modality for patients with heart failure and electrical dyssynchrony. A current limitation is that approximately 30% of patients do not respond, and identification of patients at greater risk for suboptimal outcome remains challenging.
