HONOLULU – Honolulu Police Chief Lee Donohue left Queen’s Medical Center Saturday, a week after he collapsed with an irregular heart rhythm. 

   The chief, 57, walked out of the hospital, accompanied by family and friends.

   Dr. Raymond Itagaki, Donohue’s cardiologist, said a small defibrillator was implanted in his chest to monitor his heart rhythm. Police officers used a defibrillator on Donohue after he collapsed during a fitness competition at the police academy last Saturday.

   Doctors said the officers’ action probably saved Donohue’s life.

   Police officers are being trained in the use of the defibrillator, which the Police Department hopes to place in all patrol cars. Donohue had campaigned for funds to purchase the machines.

   Itagaki said Donohue will rest for another two weeks before returning to work.

   Deputy Chief William Clark is in charge of the department in Donohue’s absence.
