Stress Echo

This is a normal echocardiogram test that is undertaken firstly at rest on the couch and then under ‘stress’ conditions. The heart is put under stress by making it work hard and this is achieved either by exercising on a bike or by injecting a drug that makes the heart pump more quickly and vigorously. This test is useful to assess the blood supply to the heart, to assess heart valve and to get an idea of how well a heart will respond to a bypass operation or a stent procedure.

What to expect

this test usually takes about 40 minutes. The rest images are taken as usual. The test will then be repeated either whilst you are exercising on a bike or whilst a drug is injected into one of the arm veins.
