Wearing Apollo’s a little gadget called a Holter Monitor allows you to track your heart's activity for 24 to 48 hours. It is used to detect arrhythmias, track the effectiveness of heart drugs, or identify the origin of symptoms such as palpitations, fainting, or dizziness that may not be detected by a standard ECG. 

The monitor connects to a portable gadget by affixing tiny stickers, or electrodes, to your chest. While the monitor records your heart's activity and provides a thorough report on how your heart is functioning both during the day and at night, you can carry on with your everyday activities.
