What are the tests performed in Cardiology?
Non-invasive investigations (tests that do not need needles or operations) include:
- n electrocardiogram (ECG) records the electrical patterns of the heart.
- Echocardiography (Echo), an ultrasound scan of the heart.
- Stress testing, TMT.
- Holter test. This records the ECG while the person is walking around for one day i.e., 24hrs.
- Ambulatory blood pressure monitoring – records the BP while the person is walking around for one day.
- Head Up Tilt Test (HUTT) – to evaluate causes of fainting
There are two modern cardiac catheterisation laboratories. In the cardiac catheterisation laboratories, (often just called the cath labs) they do invasive tests and invasive procedures are conducted.
Invasive tests involve putting needles, wires or tubes into the body.
- Cardiac catheterisation – to study the heart, a tiny tube is inserted into the heart. Then the doctor injects a “dye” that shows the inside of the heart.
- Coronary angiogram – injecting a “dye” to show the arteries of the heart.
- Electrophysiological procedures – measuring and treating abnormal electrical activity in the heart.
