What We Do​​​

The test gives us information about how your heart is working. A medication called Adenosine is used to increase the blood flow to your heart.

The test is very useful in checking whether there are any blocked arteries, ​how your heart treatment is progressing and if your heart is strong enough for surgery. It will also tell us if any recent heart surgery (like a bypass or angioplasty) has done its job and is improving your health.​
