The left vein of the heart of Mian Nawaz Sharif is not working properly.
Doctors have decided for a test next week.
The former prime minister was taken to the Sharif Medical City for tests.
The doctors said, his heart beat is not normal which is not a good sign.
They suggested Peace Maker and ICD to make it normal.
According to sources, the doctors are continuing consultations and will come up with a final decision.
Nawaz Sharif after staying two-and-a-half-hours at the Sharif Medical City went back to his home.
