Abstract: An automated external defibrillator (AED) is provided with an electrode package mounted to an exterior surface of its casing. The electrode package includes a tray, two electrodes disposed in the tray, and a cover attached to the tray. The tray can include an outer rim that surrounds a recessed receptacle portion, with the cover being attached to the outer rim so as to cover the receptacle portion. The cover has a pull tab formed thereon and graphics that illustrate how the electrodes are accessed and used. A connector is mounted to the outer rim and has a first end that extends into the receptacle portion and a second end that extends out of the tray. The electrodes are connected to the first connector end, and the second end of the connector is inserted into a socket located on the exterior surface of the casing for electrically connecting the electrodes to the unit.

Abstract: Nuclear magnetic resonance imaging of animal or human tissue is enhanced when a paramagnetic pyrophosphate compound is administered intraveneously as a contrast agent. The contrast agent is particularly useful in magnetic resonance imaging of area of tissue calcification, such as acute myocardial infarctions. Specific localization of paramagnetic pyrophosphate in ischemic and necrotic muscle cells at the periphery of a myocardial infarction makes accurate localization and sizing of the central infarct and peri-infarct zones possible.
