Goa Deputy Speaker Vishnu Wagh was admitted to the Goa Medical College and Hospital here after he complained of uneasiness during an Independence Day function.
"He is having high blood pressure and sugar. Doctors attending him told me that he is in a critical stage. He is currently under observation," GMCH Dean Dr Pradip Naik told PTI.
Wagh was rushed to GMCH last night following chest pain during an event at Kala Academy here.
Initially, it was suspected to be a case of cardiac arrest, but upon detailed examination no blockage was found in the heart, Naik said.
He said Wagh collapsed after being brought to GMCH and was attended to immediately by a team of doctors.
Wagh, who represented St Andre constituency, had suffered a heart attack on May 15 this year when he was attending a public function to celebrate birthday of a BJP functionary Anil Hoble. He had undergone angioplasty and had recovered.
