Holter monitoring is a test that records your heart’s activity continuously for a period ranging from 24 hours to 14 days. It helps doctors assess your heart rhythm and identify any irregularities that might not show up during a standard exam.

Before the test, your doctor will explain the process and may ask you to avoid certain activities, like showering or bathing, while wearing the monitor. You might also be advised to keep a diary of your daily activities and any symptoms you experience, such as palpitations or dizziness.

During the monitoring period, small adhesive patches, called electrodes, will be placed on your chest. These electrodes are connected to a small recording device that you can carry with you in a pocket or strap to your waist. The device will continuously record your heart’s electrical activity as you go about your daily routine.

After the monitoring period, you’ll return to your doctor, who will remove the electrodes and analyze the recorded data. This information helps them understand your heart’s function and decide if any further tests or treatments are needed. The test is painless and allows for a thorough assessment of your heart health in a real-world setting.
