Tension prevailed at a private hospital here on Monday following a heated argument between relatives of S.S. Gowda from Tepparahalli in Hirekerur taluk and doctors over his death during an angioplasty. The relatives staged a protest contending that the patient’s death was due to power failure during surgery. Later, the relatives told mediapersons that it took nearly eight minutes to start the generator after the power failed.

As a result, the surgery was delayed and because of that, the patient must have died, they alleged.

Somashekar, in charge of the hospital, however, told The Hindu that the death was due to a massive heart attack when the patient was about to be shifted to the ward after completing the surgery. He said the allegations made by the relatives of the patient were false.

His death was in no way connected to the power failure, he said, adding that the hospital had a backup generator. The UPS ensured continuous power supply to the operation theatre and to the whole hospital in case of power failure.

Police rushed to the hospital and prevented any untoward incident.

The body had sent for post-mortem and the exact cause of death will be known after the report is received.
