...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...
...advantage of it to examine herself contorted by a passion without its object. And when Jochem Hendricks (at SFMOMA) uses a specially constructed helmet to read the smallest movements of his eyes and translate those into a scribbled line drawing like Reading, he is not paying homage to the electrocardiogram. He's using a similar technology to achieve a strangely more intimate...

The ECG, which looks at how well the heart is beating, showed no change from Cheney's previous ECGs. The blood test, which measures the presence of special enzymes released by the heart during a heart attack, showed no evidence yet of any damage. But doctors know it often takes several hours for cardiac enzymes to show up in the blood after a heart attack, so follow-up tests were ordered...

Patients are advised to use the drug only as a last resort. And before they do, doctors should perform an electrocardiogram to check for ticker trouble...

It was fascinating to watch the President's speech with a window at the bottom of the television screen showing the Dow Jones average moving like an electrocardiogram. The Dow was in losing territory when the Clinton started speaking, and rose steadily into the plus column as he went...
