Mets’ Pulsipher to Wear Monitor to Test Stress

New York Met pitcher Bill Pulsipher underwent another set of tests Saturday to determine why he collapsed last week.

Internist John Olichney and his son John M. Olichney, a neurologist from UC San Diego, gave Pulsipher a thorough examination and studied all of the hospital test results, General Manager Steve Phillips said.

“On Monday we’re going to schedule Bill for a stress echocardiogram,” Phillips said. “We’re going to put a halter monitor on him, which he’ll wear for a 24-hour period.”

Pulsipher collapsed unconscious in his bathroom Wednesday and was taken to a hospital with breathing difficulties and a slow heartbeat. He was released Thursday and worked out Friday.
