External Mechanical Cardiac Stimulation
New England Journal of Medicine, 1976TEMPORARY cardiac stimulation in the emergency resuscitation from cardiac arrest and in other less urgent conditions is generally applied by way of a pervenous endocardial electrode and an external...

A microcomputer-controlled cardiac stimulator
Journal of Medical Engineering & Technology, 1991Detailed investigation of abnormal heart rhythms requires electrical stimulators that can deliver sophisticated sequences of stimuli to the heart under controlled laboratory conditions. A dual-channel stimulator that provides an appropriate hardware interface between a controlling microcomputer and the patient is described.

Noninvasive temporary cardiac stimulation
Critical Care Medicine, 1985A new noninvasive temporary cardiac pacemaker-monitor has been developed to stimulate effective ventricular contraction in ventricular asystole or symptomatic bradycardia. It is quickly and easily applied, safe, and well tolerated even in conscious patients. It produced electrical cardiac responses in 105 of 134 patients; almost all of the remaining 29

Electrical stimulation of cardiac myocytes
Annals of Biomedical Engineering, 1995The influence of nonuniform cell shape and field orientation on the field stimulation thresholds of cardiac myocytes was studied both experimentally and computationally. The percent change in excitation threshold, which was studied with patch clamp technique, was found to be 182 +/- 83.1% (mean +/- SD) higher when the electric field (EF) was parallel ...

Human cardiac nerve stimulation
The Annals of Thoracic Surgery, 1992Cardiovascular responses were elicited in 12 patients undergoing cardiac operations when cardiopulmonary neural elements between the aortic root and pulmonary artery or in the right atrial ganglionated plexus were stimulated. Heart rate and left ventricular intramyocardial systolic pressure were augmented when cardiopulmonary nerves between the aorta ...

Direct electrical cardiac stimulators
Progress in Cardiovascular Diseases, 1960Summary o 1. Direct cardiac pacemaking can be accomplished by a variety of means at the present time and can be lifesaving to a large group of patients. 2. The available clinical and experimental approaches to direct stimulation have been described. 3.

A programmable cardiac stimulator
Proceedings Computers in Cardiology, 2003A programmable constant current cardiac stimulator for use in a cardiac electrophysiology research lab has been implemented with a Macintosh II interfaced to voltage to current converters. The Macintosh II was equipped with three boards from National Instruments.

In resuscitation from cardiac arrest effective circulation of oxygenated blood must be re-stored in the brief time interval available before anoxic brain damage is suffered. Circulation may be effected temporarily without cardiac contractions by emergency mechanical compression of the heart (“cardiac massage”), either externally through the closed ...
