The corruption trial of Nikita Belykh, the liberal former governor of Russia's Kirov region, was interrupted when an ambulance was called after the defendant felt ill.
The Presyna district court in Moscow said that Belykh felt ill when transported from a detention center to the court, where his trial resumed on October 11.
It said the defendant was diagnosed with high blood pressure.
The medical team attended to Belykh and the trial proceeded.
The former governor's trial started on September 5.
Russian investigators detained Belykh in June 2016, saying they had caught him accepting a bribe of 400,000 euros ($475,000) at a restaurant in the capital.
Belykh has pleaded not guilty, calling the case against him "a police provocation."
Once a leader of a liberal opposition party, the Union of Right Forces, Belykh was one of the few provincial governors not to be closely allied with President Vladimir Putin.
Putin dismissed him from his post after his arrest.
