A federal judge agreed on Friday to delay the trial of John Edwards for at least two months.
Judge Catherine Eagles did not disclose the medical condition afflicting Edwards, but said she had received letters from his cardiologist.
In those letters, the judge said the doctors wrote that the condition was treatable and the former U.S. presidential candidate had a good chance of success if the course of treatment were followed.
"The letters from Mr. Edwards' physicians are pretty clear this is a serious condition," Eagles said.
She indicated that his condition has given him problems on three occasions since being diagnosed in December. She said his condition has affected his daily life and makes it difficult for him to drive.
"Certainly the ends of justice are served by continuance, given the seriousness of his medical condition," Eagles said.
Edwards needs a procedure in February, according to the judge.
She asked his lawyers to give her a medical update on Feb. 28.
