A special court, constituted to try 70-year-old Musharraf on charges of high treason for imposing emergency in 2007, had issued a warrant on Friday, carrying a bail bond of Rs 2.5 million.
The court had also ordered the Islamabad police to submit a compliance report to the court on February 7.
Police were able to serve the warrants only after waiting for two-and-half hours at the reception of the medical facility, media reports said.
Musharraf's lawyers, who were also present at the hospital, provided the police with details about the surety bonds of Rs 2.5 million.
Musharraf was admitted to the Armed Forces Institute of Cardiology in Rawalpindi after he developed heart problems while being driven to the special court.
