ATI's first R200-based card was the Radeon 8500, launched in Aug 14, 2001. In the end of Oct, 2001, ATI launched the Radeon 8500LE (later re-released as the Radeon 9100), an identical chip with a lower clock speed and slower memory. Whereas the full 8500 was clocked at 275 MHz core and 275 MHz RAM, the 8500LE was clocked more conservatively at ...
Currently, C-reactive protein is not recommended as a cardiovascular disease screening test for average-risk adults without symptoms. [58] The American Heart Association and U.S. Centers for Disease Control and Prevention have defined risk groups as follows: [59] [26] Low Risk: less than 1.0 mg/L; Average risk: 1.0 to 3.0 mg/L; High risk: above ...
The heart is a muscular organ found in humans and other animals. This organ pumps blood through the blood vessels. [1] Heart and blood vessels together make the circulatory system. [2] The pumped blood carries oxygen and nutrients to the tissue, while carrying metabolic waste such as carbon dioxide to the lungs. [3]

RAP reflects the amount of blood returning to the heart and the ability of the heart to pump the blood into the arterial system. RAP is often nearly identical to central venous pressure (CVP), [ 1 ] although the two terms are not identical, as a pressure differential can sometimes exist between the venae cavae and the right atrium.
Cardiopulmonary bypass (CPB) or heart-lung machine, also called the pump or CPB pump, is a machine that temporarily takes over the function of the heart and lungs during open-heart surgery by maintaining the circulation of blood and oxygen throughout the body. [1]
Cardiac index is a critical parameter in evaluating cardiac performance and the adequacy of tissue perfusion. In healthy adults, the normal range of cardiac index is generally between 2.6 to 4.2 L/min/m².
The primary purpose of a pacemaker is to maintain an even heart rate, either because the heart's natural cardiac pacemaker provides an inadequate or irregular heartbeat, or because there is a block in the heart's electrical conduction system. Modern pacemakers are externally programmable and allow a cardiologist to select the optimal pacing ...
