Gandhi spent some time in the Cardio-Neuro Centre of the hospital where Swaraj is undergoing treatment since April 25.
Swaraj has had a good rapport with Gandhi and his mother and Congress President Sonia Gandhi since she was the Leader of Opposition in the last Lok Sabha.
The premier hospital had yesterday said that Swaraj continued to show rapid improvement and would be discharged soon.
AIIMS has also set up a medical board for formulating a combined treatment strategy for the minister.
Both Sonia and Rahul had, last year in Parliament, walked up to the Minister to ask about her well being when she was unwell.
