The Member of Parliament from Pune, who arrived at around 10:00 am today, has not yet been admitted to the hospital.
"Kalmadi is likely to be admitted at the institute's cardio neurosciences department late in the afternoon," a source in the hospital said.
A three member team of doctors including, Dr M V Padma, cardiologist Dr Rakesh Yadav and Dr Aarti Vij, has been formed to conduct tests on him.
Kalmadi, who is in jail for his alleged involvement in CWG scam, was first taken to Deen Dayal Upadhyay Hospital on July 12 after he complained of dizziness.
"After tests, the hospital referred him to Lok Nayak Jai Prakash Hospital to undergo an MRI test of the brain. The MRI was done on July 19," DIG Tihar Prisons R N Sharma had said earlier.
The test results stated in medical jargon, "Diffused cerebral atrophy with old ischemic changes in brain parenchyma with calcified granuloma in caudothalamic groove on left side (of his brain)".
"After reading the MRI reports, DDU doctors advised us to show him to a good neuro specialist either at AIIMS or GB Pant hospital. Kalmadi, being an MP, requested in writing to be admitted to AIIMS. That is why he is being taken there for further treatment," Sharma had said.
67-year-old Kalmadi was first taken to AIIMS on July 28 for medical investigations and doctors had opined that he be admitted there for a ''short duration''.
After the check-up, Kalmadi had dismissed reports that he was suffering from dementia, a disease related to memory loss.
