Abbreviated ECG or EKG, an electrocardiogram provides vital information about the electrical activity of your heart. It is a key element in the detection of various cardiac complications.
Learn more about the test's requirements, its reading, and how to interpret certain abnormalities with a home-based wearable electrocardiogram.
An ECG is the graphical representation of the heart’s electrical activity recorded via electrodes. It can detect many cardiovascular pathologies.
With each heartbeat, an electrical signal travels through your heart. This signal causes your heart to contract and pump blood.
The role of an electrocardiogram is to record and amplify this electrical activity for a few seconds. It takes the form of a wave on a graph that reproduces cardiac cycles. Doctors can deduce the heart rate and rhythm by interpreting the tracing.
Heart rate gives you information about how fast your heart beats. The speed can vary as a result of physical activity, emotional responses and certain pathologies. According to the European Society of Cardiology, "a normal heart rate usually averages 60 to 80 beats per minute (b.p.m.)." (source: escardio.org)
A normal heart rhythm originates from the sinus node within the atrium. This electrical stimulus causes the heart ventricles to contract and pump out blood. Some dysfunctions may cause other heart tissues to start an impulse that will disturb the normal electrical sequence. The heart beating out of its normal rhythm is called an “arrhythmia.”
An electrocardiogram is traditionally recorded at rest, by placing small sensors called electrodes on the patient’s skin.
They are connected to an ECG recording machine, which traditionally has been used in a hospital or medical office. ECG recordings have moved out of the hospital environment with the emergence of wearable and mobile measurement systems. Whether in a medical setting or at home, the principle of recording an ECG remains the same, even if the method for obtaining the record differs.
Usually, this non-invasive test lasts from a few seconds to a few minutes. It is painless and has no side effects.
A normal heartbeat on the ECG graph will show the time the electrical wave takes to move through your heart.
By measuring time intervals on an ECG, health practitioners can see whether this electricity travel is too slow, normal, too fast, or even irregular. There are 3 distinct patterns:
The graph shows a first electrical wave as electricity moves into the left and right atrium.
This second pattern shows electricity moving through the right and left ventricles.
The final wave represents the return to a resting state for the ventricles.
ECG measurements are particularly important for people who present the symptoms of certain arrhythmias such as:
Furthermore, an ECG is also of interest for people having the following risk factors :
Arrhythmias, such as atrial fibrillation (or AFib). This is an anomaly of the heart’s electrical activity.
Electrocardiograms* performed by Body Scan only detect AFib and do not cover the detection of other heart issues, including:
Myocardial infarction. It happens when an artery that supplies blood to the heart becomes obstructed. Deprived of blood and oxygen, the heart muscle is damaged.
Evidence of heart positioning issues while looking for an electrical axis deviation.
Various other heart dysfunctions can be diagnosed by a cardiologist based on ECG results.
ECGs records a normal sinus rhythm for the following heart issues and followup tests are required to make a diagnosis.
Heart failure
Often caused by other heart conditions that damage the heart, it occurs when the heart’s pumping function is not strong enough to drive oxygen-rich blood to the body.
Valvular heart diseases
Also called VHD, they affect how the heart valves function to regulate blood flow into and out of the heart.
Some life-threatening heart diseases such as atrial fibrillation may be challenging to diagnose because AFib episodes may not occur at the doctor’s office. Keep your cardiac risk in check with our on-demand electrocardiogram solutions.
Body Scan is the first health station ever conceived. It offers a variety of cardiovascular measurements at every weigh-in including a 6-Lead ECG*.

BPM Core is a smart blood-pressure monitor with an ECG and a digital stethoscope designed to help users monitor and manage heart health.
To record an ECG that can detect AFib, place the cuff on the upper arm and place the other hand on its stainless-steel sensors for 20 seconds. Heart rhythms are tracked and displayed within the Health Mate app and will show if the heart beats too quickly and irregularly.
Equipped with advanced built-in medical sensors, the award-winning BPM Core is a 3-in-1 device that has a battery life up to 6 months.
