...room suites, Lapointe's call for change echoes those heard throughout the House system. Except the B-School has the money to improve housing and more. As the changes in Chase take place, improvements of classrooms and bathrooms--what Lapointe calls a general "redecorating and refurbishing"--will occur in the final stage of a $2 million project in Aldrich Hall. "We want to really dress then up so they'll endure another 40 or 50 years," Lapointe says...
Most members of the Class of '56 recall living by the standards they found upon arriving in Cambridge. They worked hard in classes but played the roles expected of them elsewhere. "We probably knew a lot of things were unfair." says one alum." Still, it just didn't occur to us to do anything about...
Diagnosing Arrhythmias. A large percentage of the heart disease deaths in the U.S. each year are due to arrhythmias, irreguLar heartbeats that occur when the organ's electrical impulses are disrupted. Normally, the millions of heart cells contract in specific sequence as an electric current flows from one part of the heart to another. Irregular rhythms are associated with coronary artery disease, faulty valves and heart muscle damage resulting from hypertension, heart attacks or excessive drinking. When the system shortcircuits, the heart develops abnormal rhythms, which can lead in extreme situations to fibrillation, a disorganized twitching of the heart...
These are classic symptoms of a heart attack, or what doctors call a myocardial infarction. Such attacks occur all too frequently in the U.S., striking one American every 21 seconds. They can hit suddenly, without any obvious hint of previous disease, when coronary arteries pinch shut in a spasm. But they usually result from a lifelong buildup of fatty deposits in the arteries that nourish the heart. If these coronary vessels become badly obstructed, the flow of vital blood and oxygen is reduced or cut off entirely. When that happens, parts of the heart are starved. It is the death...
Still, even a heart with significant muscle loss can effectively pump blood. The real killer is disturbances in the heart's rhythm. These are most likely to occur in the first minutes or hours after the attack, caused by irregularities in the flow of electrical signals that control the beat of the heart. The heartbeat may develop abnormal rhythms and degenerate into a useless twitching or quivering. No longer is the heart able to drive blood through the body. Cardiac arrest ensues...
