In your first cardiologist appointment, you are usually greeted by a member of the nursing staff who measures your weight and height in order to calculate your body mass
(BMI). At this stage, you are normally asked to go for one of the following tests:
Electrocardiography  (ECG) which is a tracing of the heart carried out by attaching leads
Echocardiograph (ECHO), a scan of the heart.
Both of these tests are simple and painless.
