...team stopped CPR, waiting for Jessie's heart to pump on its own. No pulse. Nurse Sandi Miller, who was keeping watch for the arrival of the arm, prayed under her breath as the team continued CPR, then paused for a third time. One doctor felt a faint carotid pulse, another felt a femoral pulse. The blood began to flow on its own. Outside, the ambulance had pulled up.

...blood pressure and reduce the risk of heart attack. Now researchers have shown that low doses of the drug may also help prevent clogged arteries. In a study of 800 adults, the blockers cut by 40% the rate at which vital arteries leading to the brain, known as the carotid arteries, built up plaque. Bonus: unclogged carotids may reduce stroke risk...
...little while. After you have seen the Headless Horseman perform three or four ride-by whackings, after you have watched Russell Crowe (Everyman, gone twitchingly postal) take off half a dozen heads, the instruments of human feeling shut down. You react to blood firehosing from a severed carotid as you would to the sight of a man spilling gravy on his tie. Whoops...
...form of noninvasive, "black blood" magnetic-resonance-imaging technique allows doctors to detect problem spots in carotid arteries, the aorta and coronary arteries before patients develop symptoms of atherosclerosis or stroke. The high-resolution MRI blacks out blood flow, offering doctors a clear view of the blood vessels and allowing them to precisely measure the thickness of their walls. Though the black-blood technique still needs improvement, doctors hope the technology will eventually identify those at risk of heart attack long before they have...
