The Event Monitor is a patient-activated device that records the heart's electrical activity (ECG). The main aim of event monitoring is to document and describe occurrences of abnormal electrical behaviour in the heart. These can be random, spontaneous, emotionally or exercise induced. These events are often rare and sometimes can be life threatening. Event monitoring is particularly useful where symptoms are only occurring intermittently and therefore may not have been documented on other diagnostic tests, including ECG and Holter monitoring. This information has been designed to assist you and your family in understanding the Event Monitor.
The Event Monitor is always scanning the ECG via the patient leads (looping method), but only stores the ECG in memory when activated by the patient. It is pre-programmed to capture and store a timed amount of ECG before and after the record button is pressed. Memory capacity varies between models, but as a minimum standard, the monitor can store five events, each being one minute long (30 secs before and 30 secs after the record button is pressed). The monitor may be worn on a belt, in a pocket or clipped to your clothes at your waist. Two adhesive electrodes (stickers) are attached to your chest, which are connected to leads from the machine.
When the patient feels a symptom, a simple press of the record button stores and records the ECG surrounding the event.

How do I pay for the Event Monitor?
For Medicare card holders the Hospital will bulk bill (please remember to bring your Medicare card), and no additional payment is required.
Are there any risks involved?
There is a small risk of minor skin irritation caused by the electrodes. Your technician will explain how best to avoid this. Please discuss any concerns with your doctor prior to wearing the monitor. You may deny consent at any time.
