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.

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 ...

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 ...
