A 54-year-old man travelling in a taxi was declared dead on Sunday evening after the cabbie found him unresponsive at the Shyambazar five-point crossing, where he was supposed to get down.
Doctors who examined Ashok Roy at RG Kar Medical College and Hospital said he had suffered a cardiac arrest.
Roy, the owner of a sari shop on Bhupen Bose Avenue in north Calcutta, boarded the taxi at Tegharia on VIP Road.
“When the taxi reached the Shyambazar crossing around 4.15pm, the driver asked Roy where he would get down. As the man was not responding, the driver asked him again,” said an officer of Shyampukur police station.
When Roy didn’t respond to the driver’s repeated queries, the cabbie took the vehicle to a nearby police kiosk. “We thought he (Roy) had passed out. We took him to RG Kar hospital, where doctors declared him dead,” said the officer.
“The man probably suffered a ventricular fibrillation, where after an attack the heart beats 200 to 300 times per minute against the normal rate of 70-75. But these beats are ineffective as no blood is pumped out of the heart and the person dies almost immediately,” said critical care expert Subrata Maitra.
