Pregnancy with an Artificial Pacemaker

Obstetrical & Gynecological Survey, 1987
Complete heart block in pregnancy is not a common encounter. The first case was reported in 1914 by Nanta and today some 100 cases are documented. Heart block may be congenital or acquired secondary to cardiac surgery, rheumatic heart disease, or infective disorders.

Nursing the Patient With an Artificial Pacemaker

AJN, American Journal of Nursing, 2022
Editor's note: From its first issue in 1900 through to the present day, AJN has unparalleled archives detailing nurses' work and lives over more than a century. These articles not only chronicle nursing's growth as a profession within the context of the events of the day, but also reveal prevailing societal attitudes about ...

Gene- and cell-based bio-artificial pacemaker: what basic and translational lessons have we learned?

Gene Therapy, 2012
Normal rhythms originate in the sino-atrial node, a specialized cardiac tissue consisting of only a few thousands of nodal pacemaker cells. Malfunction of pacemaker cells due to diseases or aging leads to rhythm generation disorders (for example ...

Self‐Powered Cardiac Pacemaker Enabled by Flexible Single Crystalline PMN‐PT Piezoelectric Energy Harvester

Advanced Materials, 2014
A flexible single-crystalline PMN-PT piezoelectric energy harvester is demonstrated to achieve a self-powered artificial cardiac pacemaker. The energy-harvesting device generates a short-circuit current of 0.223 mA and an open-circuit voltage of 8.2 V ...

ARTIFICIAL CARDIAC PACEMAKERS.

Journal of the Medical Association of Georgia, 1996
Nine patients with complete heart block and Stokes-Adams disease were treated with subcutaneously implanted, fixed-rate, artificial cardiac pacemakers. All of these patients were refractory to medical treatment and confined to bed by the frequency of their attacks.

Atrial natriuretic peptide with artificial pacemakers

The American Journal of Cardiology, 1987
Abstract 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, 1968
SUMMARY 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, 2005
The 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.

Modern Pacemakers: Implantable Artificial Intelligence?

Pacing and Clinical Electrophysiology, 1988
For 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.
