What is a 24-hour ECG and why would I need this?
This test is a way of continuously recording your heart rhythm and the hearts electrical activity over a
period of time. The tests can help diagnose various symptoms that do not happen very often or have not
previously been picked up by an ECG (heart tracing). The heart produces tiny electrical impulses which
cause the heart muscle to contract. These impulses can be detected and recorded by an ECG. This test
may be recommended to help diagnose symptoms such as palpitations, dizzy spells or black outs.
