Ahmed Raza Kasuri, a key member of Musharraf's legal team, said doctors at the Armed Forces Institute of Cardiology in Rawalpindi could make a recommendation to send the 70-year-old former army chief abroad for treatment.
"Doctors' opinion will be final and the court is bound to follow it," he told reporters outside the hospital where Musharraf is being treated since he fell ill while travelling to a special court yesterday to face charges of high treason for imposing emergency in 2007.
His legal team expects to get his medical reports by Sunday evening and they would be presented in the special court during the next hearing on Monday, Kasuri said.
"No one can challenge the doctors' report - if the doctors advise to take him abroad for medical treatment then the doctors' opinion will be carried out," he said.

Musharraf's condition "remains static but not dangerous" and he was in the intensive care unit, he said. He added that Musharraf was "under stress" but refused to go into details.
Dawn News quoted its sources as saying that three vessels in Musharraf's heart "are blocked and he would either require an angioplasty or a heart by-pass". The possibility of his treatment in Dubai or London was being considered, it said.
The sources said Musharraf was being administered blood thinning medication. They said he had experienced extreme mental stress which led to chest pains.
So far, no statement has been issued by the Armed Forces Institute of Cardiology about Musharraf's condition.
Musharraf is the first army chief to face trial for treason. If convicted, he could get life imprisonment or the death penalty. The trial has also raised the possibility of a standoff between the civilian government and the powerful army.
The former President is facing several criminal cases dating back to his rule and he is also barred from travelling out of Pakistan.
