General instructions for Holter monitor (24-hour electrocardiogram)
It is a non-invasive test in which a small portable device connected to your chest via cables is placed on you, in order to record the electrical activity of your heart during your usual daily routine.
- Fasting: No fasting is required. You can (and should) eat and drink completely normally before and during the test.
- Medication: Continue taking your medication as usual, unless your cardiologist has explicitly told you otherwise.
- Clothing and Accessories: Come to your appointment wearing comfortable two-piece clothing (trousers/skirt and top). A loose garment that fastens at the front (with buttons) is preferable, as it will make it easier to place the leads and will hide the device. Avoid necklaces that could rub against the chest leads.
- Specific Requirements: You should shower before your appointment, since once the device is fitted you will not be able to bathe or get your chest wet for the 24 to 48 hours the study lasts. Also, do not apply creams, lotions or oils to your chest, so that the adhesive electrodes do not come off. You will be asked to keep a small "diary" noting any symptoms you feel (such as palpitations or dizziness) and the time they occurred.
