The advice marks the first time a medical-guidelines body in the U.S. has urged wide use of an electrocardiogram, which charts electrical activity in the heart, to screen a presumed healthy population for abnormalities.
But there is debate among experts about the value of using the test to screen such a large pool of patients to detect a rare condition. The hope is that such a test -- in combination with a comprehensive checkup -- will help to avoid the rare cases of sudden cardiac arrest that have been linked to the widely used medicines.
