Atrial natriuretic peptide with artificial pacemakers
The American Journal of Cardiology, 1987Abstract Accumulating evidence indicates that atrial natriuretic peptide (ANP) is a circulating hormone in humans. 1–4 Plasma levels of ANP increase in patients with various heart diseases such as paroxysmal atrial arrhythmias 2 and congestive heart failure.

The Vectorcardiographic Findings in Patients with Artificial Pacemakers
Diseases of the Chest, 1968SUMMARY The vectorcardiographic findings in 20 cases with artificial pacemakers (intravenous or implanted) are presented. In patients with implanted pacemakers, the vectorcardiogram displays two major patterns: (a) the main QRS loop is directed to the right, anteriorly and inferiorly; (b) the QRS loop is located mainly in the right posterosuperior ...

Radiotherapy to patients with artificial cardiac pacemakers
Cancer Treatment Reviews, 2005The in vitro studies show that the modern cardiac pacemakers utilising the complementary metal-oxide semi-conductor (CMOS) circuitry can be adversely affected by therapeutic radiation. However, the published clinical data are sparse regarding the safety of radiotherapy delivery to patients with artificial pacemakers.

An artificial cardiac pacemaker is a medical device used for regulating the beating of the heart by using the electrical impulses delivered by the electrodes on contraction of the heart. The pacemaker used at present produces a fixed heart beat and it does not vary according to human activities.

Modern Pacemakers: Implantable Artificial Intelligence?
Pacing and Clinical Electrophysiology, 1988For over twenty years computer programs have been written for applications in cardiology. Approximately one decode ago the first Expert Systems using knowledge on cardiology were built. The use of Expert System shells enabled a breakthrough. Many systems were developed, each covering a small part of cardiology.

Ventricular arrhythmias in a patient with artificial pacemakers
The American Journal of Cardiology, 1967Abstract The case of a patient is reported whose implanted pacemaker manifested different mal-functions, including the development of ventricular premature beats, tachycardia and fibrillation. The ventricular premature beats were satisfactorily controlled when the catheter pacemaker was turned off and the heart was paced only by the internal ...

Minerva medica, 1977
The new generation of pacemakers satisfy three basic requirements; histocompatibility, small size, and long life. Resins have been abandoned in favour of titanium cases. These are completely sealed and there is no risk of infiltration or histotoxicity. In addition, the employment of low consumption circuits and new sources of energy, especially lithium,

Tachycardia and Death Due to an Artificial Pacemaker
Annals of Internal Medicine, 1965Excerpt Chronic complete heart block is compatible with life as long as a steady idioventricular rhythm continues and the beat remains above 40/min.

Artificial cardiac pacemakers.
International journal of clinical pharmacology, therapy, and toxicology, 1990Artificial pacemakers are electronic devices used primarily to control cardiac rate in patients in whom the intrinsic heart rate is inadequate for a normal life style. These devices automatically and rhythmically provide electrical impulses to stimulate the heart.

Cardiac arrhythmias related to artificial pacemakers
Journal of Electrocardiology, 1971Summary Various cardiac arrhythmias related to artificial pacemakers are described in detail, and representative electrocardiographic illustrations are presented. The importance of recognizing malfunction of various pacemakers has been emphasized. An early manifestation of malfunction should be suspected even when the pre-set rate is altered by only ...
