Holter Monitor

What is it?


It is a small portable ECG (electrocardiogram) machine that can investigate and record the rhythm of your heart, which can potentially explain your symptoms such as dizziness or palpitations.

How it works


It can record your heart rhythm for 24 to 48hrs while you carry on your daily activities. During the 24 to 48hrs of holter monitoring, remember to:


  • Please continue your daily activities except showering.


  • Take your medications as instructed by your cardiologist, note the name of medications that you take against the time.


  • Document any symptoms (eg chest pain, shortness of breath) that you experience and also the time that they occur.


  • Document your activities and the time that you engage in them.


  • Do not shower, bathe or engage in rigorous activites while you are wearing your monitor.


  • Do not come in contact with magnetic resonance imaging (MRI) systems.
