ECGs are a type of equipment that doctors may use in a hospital or clinic to record a person’s heart’s electrical activity. They create an electrical “map” of the heart from the outside.
ECG machines come with sensors that attach to people’s skin. This allows them to record the electrical signals that the heart produces.
At-home ECG monitors have built-in sensors that record the heart’s activity. People can hold their fingers against these sensors or wear them on their wrists or body.
Some devices also come with built-in screens that allow users to view their heart rhythm. People can also buy products that they can connect to a smartphone to collect their data. People can then share their readings with a doctor.
Doctors may use ECGs to detect several health conditions.
People can also use portable ECG monitors at home to check their heart rate and rhythm and use the data to discuss any symptoms or patterns with a doctor.
Conditions that ECGs can detect
The National Health Service (NHS) states that ECGs can detect certain heart conditions. These include the following.
Arrhythmia is a condition that causes an irregular heartbeat. A person’s heart may beat too fast, too slow, or with an irregular rhythm.
This condition affects
Coronary artery disease
Coronary artery disease affects around
The condition occurs when fatty substances build up inside the lining of the coronary arteries and block the heart’s blood supply. Doctors may diagnose coronary artery disease by using an ECG.
A heart attack occurs when the heart does not have enough blood supply. Some people may not notice that they have had a heart attack.
Symptoms of a heart attack include:
Doctors may use ECGs to detect this condition. However, if a person has any symptoms of a heart attack, they should seek emergency medical attention immediately.
Using an ECG monitor at home
Personal ECG monitors are similar to the ECGs that doctors use. People may use these devices to monitor their heart health at home.
However, a person should never use a personal ECG monitor as a replacement for medical advice. If the person has any symptoms that may indicate the presence of an underlying health condition — such as heart palpitations, dizziness, or fainting — they should seek immediate medical advice.
An individual should speak with a doctor to decide which at-home ECG monitor is best for their needs.
Below are some factors that people may wish to consider when looking for an at-home ECG monitor:
- Connectivity: Some ECG monitors come with Bluetooth connectivity and can connect to smartphone devices to track the user’s data and readings.
- Memory: This allows the user to save previous readings, and it can be useful if they want to show the results to a doctor.
- Size: If a person intends to use an ECG monitor while traveling, they should check its dimensions to ensure that it fits in their pocket.
- Measurement time: Most devices take 30 seconds to take one reading.

People should follow all manufacturer instructions when using a portable ECG monitor.
Although instructions may vary, some general tips for using a portable ECG include:
- not using the ECG monitor while exercising, as the measurement is less likely to be accurate
- staying still while using the ECG monitor
- placing the sensor on an area where it can register a pulse, such as the fingers, wrist, or chest
- taking measurements on dry skin
- taking measurements on bare, hairless skin
- removing any jewelry that would be close to the sensors
A portable ECG monitor is not a replacement for medical advice. If a person’s reading shows any unusual heart rhythms, they should seek medical advice immediately.
According to the Centers for Disease Control and Prevention (CDC),
- Following a healthy diet: People should try to eat foods that are low in saturated fats and add fruits and vegetables to their diets.
- Exercising regularly: If possible, individuals should get 150 minutes of moderate intensity aerobic activity or 75 minutes of vigorous intensity aerobic activity every week.
- Managing stress: Long-term stress can increase a person’s heart rate and blood pressure, so people should try to limit this.
- Avoiding or stopping smoking: This also applies to people who do not smoke, as they can still develop heart disease or lung cancer from secondhand smoke.
People who are monitoring their heart health should also attend follow-up appointments and contact a doctor if they notice any new or worsening symptoms.
A person should contact a doctor if they believe that they are experiencing any symptoms that may indicate a heart condition. These symptoms can include:
A doctor will perform tests to diagnose any conditions that can impact heart health. They will also determine a treatment plan to monitor and treat any symptoms of a heart condition.
Portable ECG monitors can be useful for people who want to monitor their heart health at home or when traveling.
There are various brands that manufacture these types of devices. A person should check the features they offer and choose one that is most suitable for their needs.
People should not use these devices to diagnose or treat a medical condition. If a person believes that they may have a heart condition, they should contact a doctor as soon as possible.
