An electrocardiogram (EKG) is a noninvasive test that measures your heart’s electrical activity. It’s an important tool that healthcare professionals use to detect heart conditions, particularly if you’re at risk.
If you get an EKG and the results come back abnormal, it can point to a range of heart problems—some benign, some more serious.
That’s why it’s important to see a doctor if you have abnormal EKG results. They will be able to give you an accurate diagnosis and help you begin treatment, if necessary. This article will help you understand what abnormal EKG results could mean and what next steps you may need to take.
What is an EKG?
An electrocardiogram (EKG or ECG) is a quick, noninvasive test that measures your heart’s electrical activity.
During an EKG, technicians attach electrodes to your chest, arms, and legs. These electrodes detect the tiny electrical signals produced by your heart. The EKG machine records these signals as waves that doctors can analyze.
EKGs are essential for detecting a range of heart conditions, including arrhythmias and heart attacks. They’re especially useful for people who have risk factors for heart disease, like high blood pressure, high cholesterol, or a family history of heart problems.
Doctors may order an EKG if you have chest pain, shortness of breath, heart palpitations, or dizziness.
Common Causes of Abnormal EKG Results
An abnormal EKG can be a sign of several different heart conditions. Here are some of the more common:
Arrhythmias
Arrhythmias are irregular heartbeats that happen when there’s a problem with your heart’s electrical system. Some common arrhythmias are atrial fibrillation, tachycardia (a too-fast heartbeat), and bradycardia (a too-slow heartbeat).
An arrhythmia can change the timing and shape of the waves on an EKG.
Heart Attack (Myocardial Infarction)
A heart attack happens when something blocks the flow of blood to your heart. This blockage can damage the heart muscle. Ischemia, or reduced blood flow to the heart, can show up on an EKG.
One of the classic signs of a heart attack on an EKG is ST-segment elevation.
Electrolyte Imbalances
Electrolytes such as potassium, calcium, and magnesium help your heart generate electrical impulses. If your electrolyte levels are too high or too low, this can disrupt your heart’s electrical activity.
High or low potassium levels, for example, can cause changes in the T wave on your EKG.
Other Causes
Sometimes, medications or structural abnormalities of the heart can lead to abnormal EKG results.
What are the signs and symptoms of an abnormal EKG?
EKGs can detect a variety of heart problems, which may or may not cause noticeable symptoms. If you have an abnormal EKG, you may also experience:
- Chest pain
- Shortness of breath
- Heart palpitations (a racing, fluttering, or pounding feeling in your chest)
- Fainting or near-fainting
- Unusual fatigue
- Dizziness or lightheadedness
It’s also possible to have an abnormal EKG and feel perfectly fine. But even if you don’t have any symptoms, it’s important to follow up with your doctor, especially if you have risk factors for heart disease. Early detection is key to managing heart conditions and preventing serious complications.
Treatment options for conditions associated with abnormal EKG results
If your doctor has found something unusual in your EKG results, there are a variety of treatments that may help. Here are some of the most common.
Medications
Depending on what your EKG showed, your doctor might want to prescribe medication. Antiarrhythmic drugs are often used to control irregular heartbeats. Beta-blockers and calcium channel blockers can help lower your heart rate and blood pressure.
Procedures
Several procedures are used to treat heart conditions. Angioplasty and stent placement are used to open blocked coronary arteries. Catheter ablation can get rid of abnormal electrical pathways in the heart.
- During angioplasty, a tiny balloon is inflated to widen a narrowed artery.
- With stent placement, a tiny mesh tube is inserted to keep the artery open.
- Catheter ablation uses radiofrequency energy to destroy the tissue that’s causing the problem.
Lifestyle modifications
You may also need to make some changes in your daily habits to improve your heart health. Eating a heart-healthy diet, exercising regularly, and quitting smoking can all make a big difference.
It’s also important to manage your weight and try to reduce stress in your life.

Frequently Asked Questions about Abnormal EKGs
What does an abnormal EKG mean?
Basically, it means your heart’s electrical activity isn’t following the usual pattern. It doesn’t automatically mean something’s seriously wrong, but it’s a signal that you should probably get it checked out further.
How often should I get an EKG?
That really depends on your own situation – your risk factors, your medical history, all that jazz. Best bet is to chat with your doctor about what’s right for you.
Can an abnormal EKG be normal sometimes?
Yep, definitely. Sometimes these things come and go. An abnormality might show up on one EKG but not the next.
What should I do if I have an abnormal EKG?
Don’t freak out, but do follow up with your doctor. They’ll likely want to run some more tests to figure out what’s going on.
Can stress cause an abnormal EKG?
Stress can sometimes throw things off temporarily, but it’s crucial to make sure there isn’t something else going on underneath. Rule out the serious stuff first.
Wrapping Up
An abnormal EKG can point to a number of different heart conditions, so it’s important to follow up with your doctor and take the next steps.
Proactive heart health management is key to staying well. Regular check-ups and EKGs, when appropriate, are crucial for keeping your heart in good shape.
