What is a Holter Monitor?
A Holter monitor involves monitoring your heartbeat constantly over a 24-hour period for any arrhythmias or abnormal heart rhythms. It is also known as a 24-hour ECG monitor. Several electrodes are attached around your chest – these are connected by wires to a recorder. You are requested to fill in a diary of the times you feel any palpitations or events, and return the unit together with the diary the next day. We will then analyse the monitor recordings using specialised computer software, and provide a report to your referring doctor, usually within one week. Based on the results, recommendations for treatment will be provided. This may involve ongoing observations, additional or change in medications, or even a pacemaker in some circumstances.
