Doctors have suggested immediate hospitalisation of yoga guru Ramdev whose indefinite fast against corruption and black money entered seventh day today as his health parameters continued to remain "worrisome".

"His blood pressure is 104/70 which is low and pulse rate is 58 per minute which is also low. If his pulse rate and BP continue to go down, it may put some pressure on his heart. We found that his health is going down. It is worrisome," Chief Medical Officer Yogesh Chandra Sharma said after conducting medical examination of Ramdev.
