Patients could be diagnosed and treated for heart disease sooner as more tests now need to be carried out within an eight week waiting time target.
Cardiovascular (heart and circulatory) disease is the biggest killer in Wales, with more than 9,000 deaths each year.
Currently, only those waiting for stress tests and an echocardiogram have to be seen within eight weeks.
