Some tests, long ignored, showed signs of heart illness at Harlem Hospital Center

New York City's public hospital system said that some of the thousands of heart test results that were never sent to doctors at Harlem Hospital Center since 2007 had shown signs of abnormal heart function. Hospital officials made the admission a day after acknowledging that results of 4,000 of the echocardiograms tests had never been seen by doctors because of a practice of allowing technicians to read them first, the New York Times reports.
