Kartar Kaur Sangha was admitted to a Ludhiana hospital on February 24 after a drop in her blood pressure.

An 118-year-old woman in Punjab registered her name in the Guinness World Record to become the oldest person to be operated upon, doctors at a hospital in Ludhiana confirmed on Thursday.

Kartar Kaur Sangha was admitted to Satguru Partap Singh Apollo Hospital in Punjab's Ludhiana on February 24 after a drop in her blood pressure.

Doctors then implanted a pacemaker in her heart to improve her BP.

"To operate upon her at this age was a challenge for us but she is doing fine. According to the Guinness World Record, a 107-year-old from Lucknow holds the record for being the oldest person to receive pacemaker implantation. We have now applied for both the Guinness Book of World Records and the Limca Book of Records," Ravinder Singh, Ms Sangha's younger brother, said.

"We are confident that she has broken the record for being the oldest living person to be operated upon. I am proud of her for being strong," he added.

Ms Sangha is also the oldest living person in the world, beating the record of 116-year-old Kane Tanaka from Japan.

"This is the first time she has been admitted to a hospital because of a major problem. Otherwise, she has remained healthy her entire life," her 90-year-old daughter Baljinder Kaur said.
