What is an Electrocardiogram (EKG/ECG)? What Can It Tell You? What Are Normal Values?
What is an Electrocardiogram (ECG or EKG)?
An Electrocardiogram (EKG) is a test that measures the electrical activity of your heart. During the procedure, a doctor or nurse places electrodes at various points on your body. As your heart beats, it generates electrical impulses, which are then picked up by these electrodes and converted by the EKG machine into a line graph showing your heart’s rate and rhythm.
The results of an EKG can provide doctors with several pieces of information about your heart, including its rhythm, regularity of beats, and electrical conduction. This helps in detecting abnormalities or potential diseases such as an enlarged heart, heart muscle damage, myocardial ischemia (lack of blood flow to the heart muscle), or imbalances in certain electrolyte levels in the body.
For EKG screening, it’s recommended for individuals aged 35 and older, or those with risk factors for heart disease such as high blood pressure, high cholesterol, diabetes, or a history of smoking. It’s also advised for people who work at high altitudes or in confined spaces. If any abnormalities are detected, it’s important to consult a specialized cardiologist for further diagnosis and treatment.
What’s an EKG For?
An Electrocardiogram (EKG/ECG) is a crucial test that helps doctors understand your heart’s information and any abnormalities, leading to a more effective diagnosis. According to a 2022 report from Thailand’s Ministry of Public Health, over 70,000 Thais died from cardiovascular diseases, averaging 8 people per hour, and this trend is expected to increase annually. This can be due to many risk factors, including age, gender, family history, high blood pressure, high blood sugar, high cholesterol, obesity and overweight, as well as behaviors like regular smoking or alcohol consumption. Therefore, to understand the risks of various heart conditions, an EKG is one of the top methods doctors choose because it’s convenient, fast, painless, and requires no special preparation. Importantly, it’s suitable for all ages and genders.
What Can an EKG Tell You?
Doctors can assess heart health from the EKG graph. An EKG can indicate several important pieces of information, from the heart’s rhythm and the structure or size of each heart chamber, to potential underlying abnormalities, as follows:
1. Basic Heart Function
An EKG can check if your heart’s rhythm is regular by recording your heart rate (normally 60-100 beats per minute) and how well all four heart chambers coordinate their work.
2. Condition of the Heart Muscle
Doctors can perform a preliminary assessment of your heart muscle’s strength, including its thickness, any blood supply deficits (ischemia), injuries, or scar tissue within the heart muscle.
3. Abnormalities That Could Lead to Various Diseases
From the rhythm, heart rate, and characteristics of the heart’s electrical activity, doctors can identify abnormalities that might lead to conditions like arrhythmias, pericarditis, an enlarged heart, or coronary artery disease. Furthermore, if the EKG graph shows abnormalities, your doctor might recommend additional tests for a more detailed examination to find the cause of your symptoms in a timely manner.
Normal EKG Values: What Do They Mean?
An Electrocardiogram (EKG) provides a detailed look at the electrical activity of your heart. While a medical professional is always needed for a complete interpretation, here’s what’s generally considered normal for key parameters:
Resting Heart Rate
A normal resting heart rate for adults typically ranges from 60 to 100 beats per minute (bpm).
If your heart rate is consistently faster than 100 bpm at rest, it’s called tachycardia.
If your heart rate is consistently slower than 60 bpm at rest (and you’re not a well-trained athlete), it’s called bradycardia.
Benefits of an Electrocardiogram (EKG)
Beyond providing insights into overall heart health, an EKG offers several advantages:
It’s quick, taking only a short amount of time.
No special preparation is needed before the test.
It’s suitable for all ages and genders.
It’s painless and harmless to the patient.
The heart wave measurements can be used to diagnose a variety of illnesses.
It can indicate potential risks or undetected abnormalities.
Who Should Get an EKG?
An EKG can be done by anyone, regardless of age or gender. It’s recommended to have one at least once a year as part of your annual health check-up. Additionally, those in the following high-risk groups should consider getting an EKG:
Individuals aged 40 and above, or those with a family history of heart disease.
Those experiencing symptoms that might indicate heart disease, such as palpitations, chest pain, or easy fatigue.
Individuals with high cholesterol, high blood pressure, high blood sugar, or diabetes.
Those who smoke or drink alcohol regularly.
Individuals who do not exercise regularly.
Is an EKG Painful?
An EKG is a safe and painless procedure. It only involves attaching electrodes to the skin to pick up electrical signals; no instruments are inserted into the body. You might feel a slight coolness from the gel used to attach the electrodes.
Furthermore, patients can undergo an EKG without needing to fast or abstain from water, and no special preparation is required. The test itself takes only 5-10 minutes, making it a convenient option for everyone, regardless of age.

Recommendations for Electrocardiogram (EKG) Testing
Wear clothing that can be easily removed or opened around the chest area for convenience during the EKG.
If you have any cardiac assistance devices, please inform the staff every time.
Avoid exercising or engaging in activities that might affect your heart rate before the test.
Ensure all metal jewelry is removed from your body, including earrings, necklaces, etc.
Turn off all communication devices while undergoing the test.
How Much Does an EKG Cost?
Initially, the cost of an EKG varies by healthcare facility. Generally, it’s often included in annual health check-up packages. The price will depend on several factors, such as the type of healthcare facility (government/private hospital), the specific check-up package chosen, current promotions, and any existing healthcare benefits like social security or health insurance.
An EKG is a fundamental and highly important test for screening and monitoring various heart conditions. It’s also easy, fast, safe, and painless, making it suitable for annual check-ups, especially for those at risk or over 40 years old. Regular testing helps doctors detect abnormalities in their early stages, allowing for effective treatment planning and reducing the risk of potential complications.
