...chest pains but otherwise seems fine. The biggest concerns are that she might be having a heart attack, that her aorta may have developed a tear or that she has a major clot in the blood vessels of the lungs. Any of these could swiftly be deadly. Her electrocardiogram comes back normal, and blood tests indicate no cardiac damage. With no compelling reason to suspect a heart attack, it's hard to make the case for ordering a cardiac catheterization. But because she continues to complain of chest pains, doctors are reluctant to send her home. So they keep...
...doctor is summoned. An unprecedented 24-hour time out is called, but even as al-Qahtani is put under a doctor's care, music is played to "prevent detainee from sleeping." Nine hours later, a medical corpsman checks al-Qahtani's pulse and finds it "unusually slow." An electrocardiogram is administered by a doctor, and after al-Qahtani is transferred to a hospital, a CT scan is performed. A second doctor is consulted. Al-Qahtani's heartbeat is regular but slow: 35 beats a minute. He is placed in isolation and hooked up to a heart monitor...
...five large, airy but rather impersonal rooms. It is furnished with several comfortable armchairs, but the President slept on a standard metal hospital bed. Before dropping off, he was put through the battery of tests drearily familiar to anyone who has been prepared for major surgery: chest X ray, electrocardiogram and CAT (computerized axial tomography) scan, a kind of super X ray of a large portion of the body. The scan showed no sign of cancer outside the colon. The tests ended about 11 p.m.; Reagan then read for a while (what, no one would say) and fell asleep...
...released many details about Kile's medical history other than to say he passed a routine physical during spring training. (It apparently was unaware that the ballplayer's father had died from a stroke after suffering a heart attack at age 44.) Kile's examination probably included an electrocardiogram (ECG), which gives doctors an indirect reading on how well the heart muscle is working by monitoring its electrical activity...
...about 30% of heart-failure patients, the damage to the heart also interferes with the electrical signals that coordinate the contraction of the left and right ventricles--its main pumping chambers. The timing is off--as can be measured on an electrocardiogram--but the blood is still moving. Would synchronizing the electrical signals with a pacemaker, doctors wondered, reduce the problems associated with heart failure in these patients...
