Superstar Rajinikanth has been admitted to the Apollo Hospital in Chennai late Monday night.
Hospital sources said that a heart-related procedure has been scheduled for Tuesday. His condition, they said, was stable.
There has been no official statement yet from the hospital or the family.
The 76-year-old actor has been busy with two films - Vettaiyan by Director Gnanavel Raja, slated for October 10 release and Coolie by Lokesh Kanagaraj. He had returned to Chennai only a few days ago.
A decade ago, the superstar had undergone a kidney transplant in Singapore. Recently, he opted out of his much talked about political plunge citing health reasons.
