...operating room, nurses pasted electrodes to the President's chest, so that a continuous electrocardiogram could be taken and shown on a TV-type screen. Dr. Didier worked a thin plastic tube through the President's throat and down his windpipe to deliver the anesthetic. Anesthetics must be chosen with special care for a patient with Johnson's heart-attack history; nitrous oxide offered the advantage of inducing only light anesthesia, so that the patient wakes up with a minimum of hangover. Dr. Didier had to use an especially thin tube to leave room for what else...
...story behind the new look at the electrocardiogram [May 13] is the story of the men who developed the device that made the new look possible-Norman J. Holter and William Glasscock. Jeff Holter was a wartime Navy scientist who returned to his home town of Helena, Mont., to take up the family business, but managed to carry on his lifelong interest in biophysics in a laboratory in an abandoned passenger station of the Great Northern Railway. To work with him, he hired another Montana native, Bill Glasscock, who had just finished his training in physics at Montana State College...

Computers are being used more widely to help in diagnosis, and Philco recently developed a "medi-chair" that can read a patient's pulse, check his respiration rate and skin response, and produce an electrocardiogram 20 seconds after he sits down in it. These and other processing techniques can leave the doctor more time to offer what no computer can-judgment and sympathy.

While an ECG will reveal some types of heart abnormality, and specifically whether a man has recently had a heart attack, it has limited predictive value-a fact made dramatically clear in the case of Lyndon B. Johnson, then Majority Leader of the Senate...
...Lingering Thought. After a series of tests-including an electrocardiogram, which proved normal-Dr. Burkley summed it up: "A respiratory infection similar to that which is prevailing at this time of year." So prevalent was the infection that Lady Bird too checked into the hospital the same...
