EKG Versus Other Heart Tests: What’s the Difference?

An electrocardiogram (EKG) is a common test that records the electrical activity of your heart. Other heart tests, such as an echocardiogram (which uses sound waves to create images of your heart), a stress test (which measures your heart’s response to exercise), and a cardiac CT scan (which creates detailed images of your heart and blood vessels), provide different information about your heart health. At PACS Urgent Care, our doctor, Dr. Walid Hammad, and his team will choose the right test based on your symptoms and medical history. For more information, contact us today or simply visit us. We have convenient locations to serve you in Alexandria VA, and Ruther Glen VA!

What heart conditions can an EKG diagnose that other tests cannot?


An EKG is a non-invasive diagnostic procedure that captures your heart’s electrical activity. This vital tool helps us to diagnose a wide range of heart conditions, such as arrhythmias, including atrial fibrillation and paroxysmal supraventricular tachycardia, heart attacks, ischemia, and heart failure. It can also help detect abnormalities in the heart’s electrical system, such as heart block and sick sinus syndrome, and even rare inherited disorders that can lead to sudden cardiac death, like long QT syndrome.

Our skilled medical professionals can interpret the EKG tracings to identify specific patterns, like the Brugada sign and Wolff-Parkinson-White syndrome, that indicate genetic predispositions to arrhythmias and cardiac arrest. It also allows us to detect thickened heart muscle, which can lead to sudden cardiac death in young athletes. Furthermore, it can provide insights into valvular abnormalities by showing changes in heart chamber sizes and pressures, which could suggest valve stenosis or regurgitation.

At PACS Urgent Care, your well-being is our first concern. In addition to having cutting-edge equipment, we have skilled medical professionals who are dedicated to offering the best possible care. Whether you’re experiencing heart-related symptoms or require routine screening, our team is ready to provide you with the EKG services you need. Don’t wait for your heart health concerns to become emergencies; visit us today for immediate, comprehensive care.

How are the results of an EKG and a cardiac PET scan different?


An EKG looks for issues with your heart’s electrical activity. This test records the heart rate, rhythm, and the conduction of electrical impulses. It can identify if your heart is beating too fast, too slow, or irregularly, and can detect signs of previous heart damage. However, due to their lower spatial resolution, EKGs are less effective in detecting small structural abnormalities.

On the other hand, a cardiac PET scan produces fine-grained pictures of the anatomy and physiology of your heart. A tiny quantity of radioactive material is used in this imaging test to show how well blood is flowing to your heart and how your heart’s pumping efficiency is. It can pinpoint specific cardiac muscle regions that are not receiving enough blood, a potential sign of coronary artery disease.

While the EKG focuses mainly on electrical activity and the PET scan provides metabolic and blood flow information, the combination of both tests provides a comprehensive view of the heart’s health. Doctors utilize both electrical and metabolic information from these tests to provide the best possible care for patients. By combining the results of an EKG and a PET scan, doctors can more accurately diagnose heart conditions, assess the severity of disease, and develop appropriate treatment plans.

Is there a difference in preparation needed for an EKG vs. other heart tests?


Our skilled team of healthcare professionals will guide you through the process. The EKG test requires minimal preparation; however, patients can be required to take off their jewelry or clothes that may interfere with the EKG electrodes. We also recommend avoiding full meals, exercise, lotions, or oils before the test to ensure accurate results.

If a stress test is required to monitor your heart while you exercise, the doctor will provide you with instructions on what to avoid prior to the test. Similarly, for coronary angiograms and certain types of echocardiograms, patients may be required to fast for a predetermined amount of time.

Echocardiograms don’t require special preparation, but patients may need to remove clothing or jewelry that could interfere with the ultrasound probe. In the case of a specific type of echocardiogram, called a transesophageal echocardiogram, health care providers will advise you to abstain from food and liquids for a few hours before the test.

For more invasive procedures like a cardiac catheterization, doctors will make sure you understand the need for sedation and possible overnight fasting for 6–8 hours. They’ll also discuss any necessary medication adjustments and the importance of having someone drive you home after the procedure.

At PACS Urgent Care, your health and comfort are our top priorities. Our team will ensure you understand each procedure and the necessary preparations to guarantee the most accurate results. Always consult with our healthcare providers for precise instructions on each specific test.

How does the cost of an EKG compare to that of an echocardiogram?


EKG, a simple, non-invasive test that records the electrical activity of the heart, can be performed by our experienced healthcare professionals right here at PACS Urgent Care. The cost of an EKG at our facility varies depending on the specific type of test conducted, but typically ranges from $50 to $400. This cost covers both the actual test and our licensed doctors’ assessment of the results.

The echocardiogram test is a more complex, noninvasive ultrasound imaging test that provides a detailed overview of the heart’s structure and function and requires specialized equipment and expertise. An echocardiography can cost anywhere between $200 to $3,000, depending on the patient’s unique medical circumstances and the test’s complexity.

It’s crucial to remember that a number of variables, including the patient’s particular medical condition, the type of test, the location, and the particular healthcare provider, might affect the cost of these tests. However, we strive hard to maintain reasonable and competitive costs. Most health insurance policies, which frequently pay for these tests if they are considered medically essential, are also accepted by us. For a precise quote, we advise patients to contact their insurance company.

At PACS Urgent Care, we prioritize your heart health. Our facility offers EKG services to quickly assess your heart’s electrical activity. Our skilled staff is dedicated to providing effective and reasonably priced care, ensuring you receive the information you need to maintain optimal heart health.
