The Ambulatory electrocardiogram (ECG) - holter monitoring is a test where the electrocardiogram (ECG) is continuously monitored for 24 to 48 hours and the signals are simultaneously recorded onto a special recorder worn by the patient.
In contrast to the usual 12 lead ECG, where the heart’s electrical signals are captured for only a few seconds, the continuous ambulatory ECG (holter) monitor can record such signals over a prolonged period at the patient’s own home or work environment. Hence, any abnormal rhythms or ECG abnormalities can be captured during the 24-hour monitoring period.
This test is useful for detecting transient rhythm disorders of the heart, which are not detected at the time when an ECG is done. This test is indicated for patients with palpitations, giddiness or fainting spells. By quantifying the amount and type of ECG abnormalities, it will be able to provide quantitative and qualitative information on the effect of the drug therapy.
The test is also useful for patients with possible ischaemic heart disease (also known as coronary artery disease) and not able to perform an exercise stress test. This test will help post procedural patients, especially those who have undergone the electrophysiological studies, to determine if the procedure was successful.
There are no risks involved. However, some patients may experience skin irritations from the prolonged contact with the electrodes. If you are allergic to plasters or micropore tapes, please inform the medical technologist as they will be able to provide you with hypoallergenic tapes and electrodes.
