A 24-hour ECG is a non-invasive test that records your heart’s electrical activity continuously for a full day.
Unlike a standard ECG, which captures a snapshot of your heart’s rhythm at a single point in time, the 24-hour ECG monitors your heart throughout its daily activities.
This extended monitoring helps detect irregularities or symptoms that might not be present during a brief examination.
You will be given a small, battery-powered device called a Holter monitor to wear in a small pouch around your neck. The monitor attaches to your body with several electrodes on your chest and arms, using a gel to help them stick.
These electrodes are comfortable and should not hurt. You can go about your usual activities during the monitoring period, but you must avoid swimming, bathing, or showering with the device on, and keep it dry at all times.
It is important to note any symptoms you have while wearing the monitor, as this will help us understand the results better. After the monitoring period, return to the clinic to have the device removed.
A cardiologist will then review the results. This test is especially useful for diagnosing intermittent arrhythmias, assessing the effectiveness of medications, and evaluating heart conditions that are not apparent during a routine ECG.
A Holter monitor is typically recommended for individuals who:

Wear clean, dry clothing and avoid applying lotions to your chest. Continue with your daily routine, but remember not to bathe or swim while wearing the monitor. Additionally, refrain from consuming caffeine and alcohol for at least 24 hours before the test, as they can affect your heart rhythm.
During a 24-hour ECG test, electrodes are placed on your chest and arms and connected to a portable device that records your heart’s activity as you go about your day. If instructed, keep a diary of your symptoms and return the device to the clinic after 24 hours for evaluation.
Once you return the ECG recorder to the clinic or hospital as instructed, the staff will remove the electrodes and dispose of them properly. If you kept a symptom diary, submit it at this time. This will help the healthcare provider correlate your symptoms with the ECG data. They will then interpret the data and recommend any necessary treatment or further tests.
