Fifty-seven-year-old Tharoor was rushed to the hospital at around 3 am after he complained of severe chest pain, anxiety and palpitation, sources at the AIIMS said. The Union minister was admitted to the ICU of the cardiothoracic centre of the AIIMS and a number of investigations including ECG have been carried out on him.
Doctors said he was brought to the hospital with a "cardiac condition" but he is stable now. A team of doctors are monitoring him at the ICU, the sources said.
Sunanda, who was upset over an alleged extra-marital affair between her minister husband Tharoor and a Pakistani journalist, was found dead in a five-star hotel room on Friday night.
The body of 52-year-old Pushkar, a woman entrepreneur who married Tharoor in August 2010, was found in mysterious circumstances in luxury LeelaPalace hotel in South Delhi.
Police sources speaking on condition of anonymity said they suspect it could be a case of suicide. Delhi police spokesman Rajan Bhagat had said inquest proceedings have been initiated by the sub-divisional magistrate of the area. Any death within seven years of marriage is legally required to be investigated by the sub-divisional magistrate.
Pushkar and Tharoor were at the centre of a raging controversy in the last two days when reports emerged that she was upset over reported text and tweet messages between her husband and Mehr Tarar, Pakistani journalist.
Tharoor had to attend two sessions and to launch a book during the Jaipur Literature Festival.
He was one of the prominent personalities to watch out during the fest.
"It is sad but Tharoor won't be able to attend the festival," festival producer Sanjay Roy said.
The minister had two sessions in the fest named The Paradoxes of Growth and Development on Saturday at 3.30 pm and History strikes back and the Collapse of Globalism on Sunday at 10 am.
Besides these, he had to launch a book authored by Louise Khurshid, wife of another Union Minister Salman Khurshid. In his last Twitter post on Friday, the Union minister had also said that he would not have been able to attend the festival due to illness of his wife.
"My wife's illness means i need to be with her & will miss all 5 events of #JaipurLitFest 2014." This was the last tweet posted by the Union Minister last evening before her death later on Friday night.
