CARDIAC PACER HAVING INPUT/OUTPUT CIRCUIT\nPROGRAMMABLE FOR USE WITH UNIPOLAR AND BIPOLAR PACER LEADSAbstract of the DisclosureAn implantable cardiac pacer having atrial\nand ventricular electrodes includes an input/output\ncircuit which can be programmed for use with either\nunipolar or bipolar pacer ...
Cardiac Output Pods are used with high performance T-type thermocouples for the determination of cardiac output in small animals (mice, rats, guinea pigs or rabbits) using the thermodilution technique. Cardiac Output Pods have a 'delta' temperature mode to allow a signal offset to be applied an...

The ability of the heart to beat without neural input enables surgically transplanted hearts to function. When a donor's heart is connected to a recipient's circulation during cardiac transplantation, no nerves are attached to the transplanted heart. The pacemaker cells in the transplanted heart ...
