Benny Hinn, the televangelist was hospitalized Friday upon returning from a trip to Brazil.
"After he arrived home he suddenly began battling fatigue and shortness of breath," his daughter, Jessica Hinn Koulianos, wrote ;in a letter posted to the Benny Hinn Ministries website.
"For those of you who know my Dad, you know that he never stops; so when he spent over a week in bed, we knew something was wrong," Koulianos wrote.
Hinn, 62, is being treated for "lack of oxygen in his cardiovascular system."
"At this moment, his physicians are conducting thorough tests, the results of which have been very positive. He is alert and in good spirits, and we expect he will be released later this week," Koulianos wrote.
"By God's grace and with the help of your prayers, we are told to expect a complete recovery," she continued.
Hinn has been in international ministry for 40 years. He has been a guest on CBN's flagship program The 700 Club.
