Screening Means Having
An Electrocardiogram (ECG), which looks at the electrical conduction pathways around the heart. Small stickers known as electrodes are placed on the client’s chest and the wires connect to an ECG machine whilst you lie still.
A printout of the heart’s electrical activity is obtained for evaluation by the cardiologist. This test is painless, non-invasive and takes only a few minutes to perform.
An Echocardiogram (Echo) is an ultrasound test (such as offered to pregnant women) which looks at the structure of the heart. From the information provided on screen, measurements are taken which give a guide to muscle thickness and size of the chambers of the heart.
Again, this test is non-invasive and painless; and it takes approximately 20 minutes to perform. The tests are performed with the client lying down on a couch or bed. For both tests clients will need to be undressed to the waist.The email says the test takes 20 minutes so it looks like the are going the whole hog rather than just an ECG.
