Do you sometimes feel things like a fluttering in your chest, a little shortness of breath, or fainting? But when you go to a doctor, those annoying symptoms are gone right away. Then even the doctor can't figure out what's really going on. That's when this little device called a Heart Monitor , or Cardiac Event Monitor, comes in handy. Let's talk about it in a little more detail today, shall we? What is it, how does it work, and what benefits can it give you?
What is a Heart Monitor?
Simply put, a heart monitor is a small electronic device that can record your heart rate and heart rhythm . It collects information about your heart's activity while you're wearing it or keeping it with you. Your doctor can then use this information to determine if there's anything wrong with your heart.
This is like an ECG (Electrocardiogram) test, but not as big as an ECG machine. This monitor is very small, smaller than a deck of cards. And since it runs on a battery, you can use it for about a month. This is especially useful for detecting abnormal heart rhythms (arrhythmias) that occur occasionally, rather than every day.
What types of heart monitors are there?
There are different types of heart monitors. Your doctor will help you choose the right one for you. Let's look at a few of the main types:
- Patch recorder: This is used to monitor heart function for about two weeks at a time. It has everything in one patch. It can be stuck to the skin of the chest.
- Symptom event monitor: This involves attaching a series of sensors to the skin of your chest. You turn on the device when you start experiencing those troubling symptoms (e.g., chest pain, fainting).
- Loop memory monitor: This also has sensors attached to your body. This is also turned on when you have symptoms. But there is something special about this one. It can record not only when symptoms appear, but also a minute or two before they appear, and a minute or two after the symptoms disappear. That is, the electrical activity of your heart, which is the same as an ECG , is recorded at that time.
- Implanted loop recorders: This is a slightly different type. It is implanted under the skin, so it can be used for several years.
When is a heart monitor used?
Your doctor may recommend using a monitor like this if your symptoms are not recurring. For example, if you only experience them once a week or once a month.
Think of it this way: Your car makes a strange noise sometimes, but when you take it to the garage, the noise is gone. There's nothing to show the mechanic. It's like when you go to the doctor and that abnormal heart rhythm might disappear at that moment.
So, it's really helpful to have a device that can record your heart rhythm right when you have symptoms. The doctor can look at those recordings and figure out exactly what's wrong.
Doctor, the information from this heart monitor can be used in situations like:
- If you fainted , had chest pain, or felt dizzy.
- If you have palpitations , that means your chest is pounding loudly, feeling like it's being pounded.
- If you have had a heart attack or stroke before.
- If you want to know if your heart is getting enough oxygen.
- If you want to check if your heart medication is working properly.
- Estimate how often your heart goes into an abnormal rhythm.
- If you have a pacemaker or ICD (Implantable Cardioverter Defibrillator) , check that it is working properly.
- If you are at risk of developing an abnormal heart rhythm, or arrhythmia .
What can you find with a heart monitor?
This cardiac event monitor can help your doctor find answers to questions like:
- Is your heart rhythm steady or irregular?
- How strong are your heart's electrical signals?
- Is the timing of your heart's electrical signals normal?
- How fast is your heart beating?
How does a heart monitor work?
Okay, now let's see how this little machine works:
1. Sensors attached to your chest measure your heart rate.
2. These sensors then send information about heart rhythms to your cardiac monitor device, either via wire or wirelessly.
3. Your heart monitor records these heart rhythms.
4. You need to send this information to the doctor. There are ways to do this, either via phone or computer.
5. The doctor will review the data you sent and check for any abnormal heart rhythms.
6. Sometimes, if the doctor sees a suspicious arrhythmia, he or she may call you and ask you about your current symptoms. Or he or she may ask you to come in for an examination.
What should you expect before using a heart monitor?
If you are given a heart monitor that is attached to your skin, the doctor or nurse will do the following:
- If there is hair on the chest where the sensor will be attached, it will be shaved .
- Cleanse and prep your skin thoroughly. If your skin is oily or sweaty, those sticky strips won't stick properly.
- Several sensors are attached to the skin of the chest with adhesive plastic tapes. The most important thing is that if you have an allergy to the adhesive in these tapes, you should tell your doctor beforehand.
- You will be given a set of sensors to use, and you will need to replace them with new ones. The doctor will tell you how often to replace them, where exactly to stick them, and how to bathe with the device.
Some heart rate monitors don't require you to wear sensors on your chest. You can wear the monitor on your wrist or hold it to your chest.
What to expect during a heart monitor test?
You need to wear or carry a device that receives information from sensors embedded in your body. Depending on the type of cardiac event recorder it is, you may need to carry it in your hand, pocket, or wear it on your wrist.
Some heart monitors require you to push a button when you experience symptoms to record your heart rhythm. Others start recording automatically when an abnormal heart rhythm is detected.
Here's a very important thing: This monitor does not protect you, because it usually does not provide real-time monitoring. The results are available after a few weeks. So if you are seriously concerned about your symptoms, please go to an emergency room immediately.
Follow your doctor's instructions exactly. Your doctor may tell you to exercise, and you may want to see what your heart monitor shows. Otherwise, do what you normally do. It's helpful to keep a record of what you do and what symptoms you experience when you're active. Also, keep a record of when you take your heart medication.
Things that can interfere with communication between sensors and the monitor
Keep your monitor at a safe distance from these things, or you may have to stop using them:
- Electric blankets, electric toothbrushes and razors.
- Magnets.
- Cell phones.
- Portable music (MP3) players.
- Microwave ovens.
- Computer tablets.
- Metal detectors.
- Places with high voltage.
The electromagnetic waves emitted by these can interfere with the functioning of the monitor. So be careful about this as well.
What to expect after a heart monitor test?
Once your doctor has received all the information they need from the cardiac monitor, you will need to return it. If you had an implantable device, your doctor will remove it and put it back in. If you had a patch device, you may need to mail it back when you are finished using it.
What are the risks of using a heart monitor?
- The adhesive on the sensor patches may cause a slight irritation to your skin , but this usually goes away after you remove the patches.
- If it is an implanted cardiac event recorder, there is a small risk of minor pain or infection due to the minor surgery that involves placing it under the skin.
Other than that, there is no pain involved in using a heart monitor. You will just feel some sensors stuck to your skin. There is nothing to worry about.
What are the results like? What do they mean?
If your doctor doesn't see any major changes in your heart rhythm, your results can be considered normal.
However, if your cardiac event monitor results show abnormal heart rhythms, you may have an arrhythmia like this:
- Heart block: Electrical signals in the heart do not travel properly.
- There are different types of tachycardia (rapid heartbeat), which can be supraventricular or ventricular .
- Bradycardia (slow heart rate).
- Atrial fibrillation: Irregular and rapid beating of the upper chambers of the heart (atria).
- Atrial flutter: The upper chambers of the heart beat rapidly, but in a certain pattern.
These names may be new to you, but the doctor will explain them to you.
How long does it take to get the results of a heart monitor test?
Depending on the type of cardiac event recorder you use, it can take anywhere from a few days to a few weeks to get the results. Ask your doctor when you can expect the results.
If the results are abnormal, what do you do next?
If your cardiac monitor results are abnormal, your doctor may decide to run more tests or start treatment right away. This will help you find a solution to your problem sooner.
When should I call the doctor?
- If you have any questions about how to use your heart monitor, or if anything is unclear about the instructions your doctor has given you, be sure to talk to your doctor.
- If you feel like you are having a heart attack, call 1990 (Sri Lanka's emergency ambulance service) immediately. If you have symptoms such as severe chest pain, difficulty breathing, or pain radiating down your left arm, don't delay.
What is the difference between a cardiac event monitor and a Holter monitor?
If you have frequent symptoms, your doctor may recommend that you wear a Holter monitor . This is also a heart monitor, but it records your heart rhythm continuously for 24 or 48 hours.
If the doctor gets enough information from the Holter monitor to accurately diagnose your condition, then you won't need to use a cardiac event monitor.
However, if the doctor doesn't get enough information to accurately diagnose the condition even after using the Holter monitor, then you may need to use a cardiac event monitor.
Who prescribes a heart monitor?
Your cardiologist , a doctor who specializes in heart disease, will recommend that you use a cardiac event monitor. He or she will use the information it collects to make a diagnosis.
Is it serious if I have to wear a heart monitor?
Yes, sometimes this can be a serious condition. If a doctor tells you to wear a heart monitor, he or she is usually trying to figure out what is causing your symptoms, such as fainting. Some abnormal heart rhythms can be more dangerous than others. But your cardiologist can't tell you exactly what type you have until he or she looks at the results of your heart monitor.
Although wearing a cardiac event monitor may seem like a bit of a hassle, it's worth it because it can help you get long-term relief from your symptoms. If you're feeling a little lazy about wearing this heart monitor, remember that it gives your doctor the information they need to diagnose your condition. Only then can they give you the treatment you need.
