A commuter who had suffered a cardiac arrest and fell unconscious at Marine Lines station on August 29 and was saved by a Western Railway (WR) staffer using an automated external defibrillator remained in a coma for several days at HN Reliance hospital and was discharged late last week, hospital authorities said.

His survival, however, may not have been possible without the efforts of Dr Akshay Mehta, an interventional cardiologist affiliated with the Rotary Club of Bombay Airport, who has worked at leading hospitals like Nanavati and Breach Candy. He has trained railway staffers at 24 stations—10 on the Western line and 14 on the Central line—over the past year.
