How does a cardiac event monitor work?

A cardiac event monitor, also known as a Holter monitor, is a small portable device used to monitor and record the electrical activity of your heart over an extended period of time. It can help detect and diagnose certain heart conditions, such as arrhythmias, palpitations, or recurring episodes of unexplained fainting.

How does it work?

The cardiac event monitor works by continuously recording your heart’s electrical signals as you go about your daily activities. It comprises electrodes that are attached to your chest and connected to the recording device. The device can be worn on a belt clip or carried in a pocket.

It captures data as you experience symptoms:

When you experience symptoms such as palpitations or dizziness, you press the event button on the monitor to capture the electrical signals during that time. This allows your doctor to correlate your symptoms with the recorded ECG data.

The recording is analyzed by a healthcare professional:

After wearing the monitor for the prescribed duration, you return the device to your doctor’s office. The recorded data is then analyzed by a healthcare professional who is specialized in interpreting ECGs. They assess the data for any abnormal heart rhythms or patterns.

A detailed report is generated:

The healthcare professional generates a detailed report outlining any abnormal events or arrhythmias. This report helps your doctor make an accurate diagnosis and determine the appropriate treatment if necessary.
