United Continental Holdings has named an interim CEO while its permanent top executive is on indefinite medical leave.
Executive Vice President Brett J. Hart will fill the position while Oscar Munoz recovers from a heart attack.

He took over for Jeff Smisek, who stepped down during a federal investigation that's looking into if the company traded favors with the chairman of the Port Authority of New York and New Jersey.
United's shares dipped about 3 percent last week after the news of Munoz's heart attack surfaced and were still down Tuesday.
