Holter Monitor

A Holter Monitor (24‑hour heart monitor) is a small device that records every heartbeat for a full day. It helps doctors check your heart rhythm over a longer period than a standard ECG. This test can detect irregular heartbeats, palpitations, or other heart problems that may not show up during a short test.  

What happens during the Holter Monitor test?  

- Electrodes applied: Three small sticky pads (ECG electrodes) are placed on your chest.  

- Monitor connected: The electrodes connect to a small monitor that records your heart activity for 24 hours.  

- Patient diary: You’ll be given a diary to write down your daily activities and any symptoms.  

- Symptom button: The monitor has a button you can press if you feel symptoms like chest pain or palpitations.  

- Appointments:
