Lotulelei was discovered to have an abnormally low Ejection Fraction, detecting that the left ventricle of his heart was pumping at only 44 percent efficiency, sources said. The normal range is between 55-70 percent efficiency.
The 6-foot-2, 311-pound Lotulelei will undergo further testing in Salt Lake City in an effort to seek more clarity with the condition, a source said. If it's a confirmed chronic condition, medical experts consider it an indication of possible heart damage.
