Country star Randy Travis is in critical condition and hospitalized in Texas with a viral heart infection, his publicist said late Monday.

According to CNN, the 54-year-old singer entered an unidentified hospital Sunday because he was having problems related to his "recently acquired viral cardiomyopathy," Travis’ spokesman Kirt Webster said in a written statement.

"Viral cardiomyopathy can be caused by 30-plus different viruses, but it's almost impossible to pinpoint which virus it is," Dr. Ramin Oskoui, a cardiologist and internal medicine specialist in Washington, told CNN. "Hospitals use viral cardiomyopathy as a 'catch all' diagnosis."

People with viral cardiomyopathy have a virus that attacks the muscles in the heart and cause it to beat slower, according to the U.S. Centers for Disease Control and Prevention website. Sometimes, the disease can cause a person’s heart to stop.

Last year Travis made headlines after he was arrested for assault and public intoxication. He got probation.

"To say that Mr. Travis' alcohol use exacerbated his problems would be pure speculation, but if someone told me alcohol played a role in his cardiac problems, I wouldn't be surprised," Oskoui said.

According to TMZ, it’s unclear what caused Travis’ condition. The celebrity news site added the Grammy winner was supposed to perform in Deadwood, S.D., Wednesday. It’s unknown if he will be able to make that performance.

The country singer is best known for hits like “Three Wooden Crosses,” “Forever and Ever, Amen,” “Diggin’ Up Bones” and “Deeper Than The Holler.”
