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 a person’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 feature 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. They can then share their readings with a doctor.

Medical News Today chose portable ECG monitors that fit the following criteria:

  • Customer reviews: We chose products that have a high average customer rating.
  • Price: We chose products available in a wide range of budgets.
  • Ease of use: We chose products suitable for people of all ages.

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, which can be useful if they want to share results with 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.

Several portable ECG monitors are available to buy online. People should carefully read the product descriptions to ensure they purchase the right device for their needs.

Many of these ECG monitors are unsuitable for individuals with pacemakers or implantable cardioverter defibrillators. If a person has any of these devices, they should contact a doctor before making a purchase.

Doctors may use ECGs to detect several health conditions.

A person 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 United Kingdom 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 up to 5% of people but may not cause any symptoms. A doctor can perform an ECG test to diagnose arrhythmia. Once they diagnose this condition, they will discuss a treatment plan with the individual.

Learn more about arrhythmia here.

Coronary artery disease

Coronary artery disease affects around 18.2 million adults aged 20 years and above in the United States.

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.

Learn more about coronary artery disease here.

Heart attack

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.

Learn more about heart attacks here.


Cardiomyopathy is a condition where the heart muscle changes size, shape, or thickness and is unable to pump enough blood. This can lead to an irregular heartbeat and heart failure.

Learn more about cardiomyopathy here.

Using an ECG monitor at home

Personal ECG monitors are similar to the ECGs that doctors use. An individual 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 they have 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.

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, including 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), 47% of people in the U.S. have one of the following risk factors for heart disease:

The CDC offers some tips to help people prevent heart disease. These include:

  • Following a nutritious diet: People should try to eat foods that are low in saturated fats and add fruits and vegetables to their diets.
  • Exercising regularly: Individuals should get 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous aerobic activity every week.
  • Maintaining a healthy weight: The CDC says people who are overweight or obese have an increased risk of heart disease.
  • Avoiding or stopping smoking: This also applies to individuals who do not smoke, as they can still develop heart disease or lung cancer from secondhand smoke.
  • Managing medical conditions: People with conditions that increase their risk of heart disease should ensure they stay on top of managing these conditions. These include high cholesterol, high blood pressure, and diabetes.

The American Heart Association (AHA) states that those who have already had a heart attack should take any medications a doctor prescribes. Taking prescription medication can lower the risk of experiencing another heart attack.

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.

People should contact a doctor if they believe 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 affect heart health. They will also determine a treatment plan to monitor and treat any symptoms of a heart condition.

When to seek emergency medical attention

People who are experiencing the following symptoms should seek emergency attention:

These symptoms may indicate a heart attack.
