Benny Hinn was admitted to the Intensive Care Unit at a hospital in Orange County, California this weekend with heart problems, although he is expected to make a good recovery.

The 63-year-old televangelist and faith healer suffered shortness of breath and was admitted to hospital after returning from a crusade in Brazil.

His daughter, Jessica Hinn-Koulianos, said in letter to supporters on the Benny Hinn Ministries website, that he had been ministering to more than 100,000 in Brazil and had felt tired on his return.

"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," she said, adding that she visited her father and he had then been to see a doctor.

After he was admitted to hospital he was treated for a lack of oxygen in his cardiovascular system and experienced "almost immediate relief".

According to Charisma News, Hinn was diagnosed with atrial-fibrillation, a relatively common heart problem that results in an irregular and often unusually fast heart rate.

"This is a challenge, but I'm getting good reports," Hinn told Charisma News. "We don't have all the answers ... as we get older, our bodies need repair."

"By God's grace and with the help of your prayers, we are told to expect a complete recovery," Hinn-Koulianos said in the statement. "More importantly, his doctors are assuring him that within a very short time he will be on his feet ministering around the world again, just as he has for over 40 years."

She thanked the ministry's partners for their prayers and asked for their continued support while her father recovers. He is expected to be released from hospital later this week.

Hinn is regarded by some as a controversial figure for preaching a prosperity message, and for his style of ministry at the large-scale 'miracle crusades' held around the world.
