Nelson undergoes shock treatment for heart

DENVER -- Chris Nelson underwent a successful procedure to shock his heart back into rhythm Tuesday at a local hospital, the Rockies announced.

Nelson was admitted to Sky Ridge Hospital on Monday after telling Rockies officials he "felt funny." Nelson was diagnosed with an irregular heartbeat, and after waiting most of Tuesday out to see if his heart would return to a regular rhythm on its own, doctors were forced to shock it.

The Rockies added Nelson, a 26-year-old infielder, to the 15-day disabled list, retroactive to July 16.

"Due to the fact that [his heart] was not able to go back into rhythm on its own, there's at least six or seven days of very limited activity he'll have," Rockies manager Jim Tracy said. "As a result, we had to put him on the disabled list."

To fill Nelson's place on the 25-man roster, DJ LeMahieu was recalled from Triple-A Colorado Springs.

In 58 games with the Rockies, Nelson, a 2004 first-round Draft pick out of Redan (Ga.) High School, has batted .256 with five home runs and 23 RBIs. He spent 15 days on the disabled list with left-wrist inflammation from May 16-31.
