In a written request to the legislature, Chavez said doctors have recommended he "begin special treatment consisting of various sessions of hyperbaric oxygenation" and physical therapy to continue "consolidating the process of strengthening health."
The request did not provide more details about the treatment or Chavez's condition and was promptly approved by allied lawmakers at a special session in the city of Maracay. National Assembly President Diosdado Cabello read the request on television.
It said Chavez would travel to Cuba as soon as Tuesday. It did not say how long he will stay, though it said he would be back by Jan. 10, when he is being sworn in for a fourth term. Venezuelan law requires presidents to receive legislative approval before leaving the country for extended periods.
