When you DIAL 105, the phone rings in the Intensive Care Cardiac Unit (ICCU) of a "hospital station" serving your area. A cardiologist picks up the phone and attends your call. He calls back to confirm your address, and then the cardiac ambulance rushes off with its team.

On reaching the patient, the team renders first aid and stabilizes him/her so that the heart does not suffer any further damage. The doctor gives the patients relatives his diagnoses and suggests what needs to be done next. 

If the doctor advices admission to an ICCU, the patient/relatives can decide which hospital to go to, depending on their financial position, the family physician's advice and other factors.
