  • You will be asked to remove any chains or other electronic objects that may interfere with the ECG reading.
  • You will be asked to remove the clothing from the upper body so that electrode sensors can be attached to your chest and abdomen.
  • To maintain contact with the skin patches of hair might have to be shaved or clipped and cleaned so that the electrodes will stick closely.
  • Electrodes patches will stick to your chest and abdomen. The Holter monitor will be connected to the electrodes via wires. The small monitor box can be worn around your waist.
  • Once you have been armed with the monitor and given further instructions, you can do your usual activities like going to work, having food, doing house chores etc. This will allow your cardiologist to detect problems that may only occur due to certain activities.
  • You will be asked to take notes of your activities while wearing the monitor. Write down any symptoms such as chest pains, dizziness or palpitations, as and when they occur.

    • Mobile phones
    • MP3 players
    • Metal Detectors
    • Magnets
    • High-frequency waves
    • Shavers
    • Microwave
