24 hour ECGs and event recorders
This test normally takes 10 to 15 minutes to fit and can be worn for anywhere between a day to 7 days depending on the type of device. The devices use sticky tabs similar to those used for an ECG (usually less of them), that stay attached to the skin for the duration of the test. The wires to the device can be worn discreetly under clothing. The device itself is about the size of an iPhone. This test is used to track and recorder the heart 's ECG tracing. If a patient experiences symptoms (fainting, dizziness or palpitations) when the device is attached then the cardiologist can understand if the heart may be the cause. It is important to fill in a diary of symptoms (and timing) when you have one of these tests.
