Stress Test
At POTS.net, we offer a range of advanced diagnostic tools, including stress tests, CPET and Stress Echo to assess your cardiovascular health and determine how your heart responds under stress.
Stress testing is essential for diagnosing various heart conditions, including coronary artery disease, arrhythmias, and heart failure. By evaluating your heart’s performance during physical exertion, we can create best treatment plans to improve your heart health and quality of life.
What is a Stress Test?
A stress test is a diagnostic tool that measures how your heart works during physical activity. During the test, you’ll typically walk on a treadmill or pedal a stationary bike while being closely monitored. The test increases the workload on your heart, mimicking conditions where your heart needs more oxygen and nutrients, helping to reveal any issues with blood flow, heart rhythm, or lung function that may not be apparent at rest.
We offer various types of stress tests to provide the most comprehensive cardiovascular evaluation, each targeting specific aspects of your heart and lung performance.
What is the Purpose of Stress Tests?
- Diagnose Coronary Artery Disease: Coronary arteries are the primary vessels that supply blood and oxygen to the heart. When these arteries are damaged or diseased—often due to cholesterol buildup or inflammation—coronary artery disease develops. A stress test helps identify this condition.
- Diagnose Heart Rhythm Problems: An abnormal heart rhythm, known as an arrhythmia, can cause the heart to beat too fast or too slow. A stress test can detect these irregular rhythms.
- Guide Heart Disorder Treatment: If you’ve already been diagnosed with a heart condition, a stress test helps your doctor evaluate whether your treatment is effective. It also provides valuable information to guide any changes in your treatment plan.
- Assess Heart Health Before Surgery: A stress test can determine if the heart is healthy enough to undergo surgeries like valve replacement or heart transplant, ensuring the procedure is as safe as possible.
What are the Different Types of Stress Tests?
- Cardiopulmonary Exercise Testing (CPET): Measures how your heart, lungs, and muscles work together during exercise to evaluate your exercise capacity and diagnose conditions like heart failure and pulmonary hypertension.
- Lexiscan Stress Testing: A pharmacological stress test for patients who cannot exercise. Lexiscan is injected to mimic the effects of exercise on the heart, allowing us to assess blood flow and detect potential blockages.
- Stress Echocardiography (Stress Echo): Combines stress testing with ultrasound imaging to visualize how your heart functions under stress, providing insight into potential heart muscle damage or reduced blood flow.

Results and Next Procedure
What Do Normal Stress Test Results Mean?
Normal stress test results indicate that your heart is functioning well under stress, with adequate blood flow and oxygen delivery during exercise. This usually means that your heart condition is stable, and no significant coronary artery blockages were detected.
What Happens if My Stress Test Results are Abnormal?
Abnormal stress test results could indicate a variety of issues, including restricted blood flow to the heart, heart rhythm abnormalities, or heart muscle damage. If your results are abnormal, we’ll discuss the next steps, which may include further testing, lifestyle changes, medications, or in some cases, procedures like angioplasty or stent placement. Our team will develop a personalized treatment plan based on your results.
Cardiopulmonary Exercise Testing (CPET)
- Cardiopulmonary Exercise Testing (CPET) is a highly specialized test that measures how well your heart, lungs, and muscles work together during exercise. CPET is often considered the gold standard for evaluating exercise tolerance and can diagnose both heart and lung conditions, as well as determine the cause of unexplained shortness of breath.
What Happens During a CPET?
- You’ll wear a face mask to measure the oxygen you breathe in and the carbon dioxide you breathe out.
- You’ll walk on a treadmill or cycle on a stationary bike, with the intensity gradually increasing.
- We’ll measure your heart rate, oxygen consumption (VO2 max), and other variables to assess how efficiently your body uses oxygen during exercise.
- CPET is particularly useful for diagnosing unexplained fatigue, shortness of breath, and evaluating the severity of heart and lung conditions. It provides valuable data for managing heart failure, pulmonary hypertension, and other cardiovascular diseases.
Is Cardiac Stress Testing Safe?
- Yes, cardiac stress testing is generally safe and is conducted under close medical supervision. The healthcare professionals at The Heartbeat Clinic are trained to monitor your heart and blood pressure throughout the test, ensuring your safety at every stage. While some people may experience temporary dizziness or fatigue, these symptoms usually resolve quickly after the test. In the rare event of complications, our team is fully prepared to respond immediately.
How long is a CPET test?
CPET tests usually last between 45 to 90 minutes, including preparation and recovery time.

Results and Next Procedure
What Do Normal CPET Results Mean?
Normal Cardiopulmonary Exercise Testing (CPET) results show that your heart, lungs, and muscles are functioning well during physical activity, indicating no significant issues with oxygen delivery or exercise capacity.
What Happens if My CPET Results are Abnormal?
Abnormal Cardiopulmonary Exercise Testing (CPET) may indicate conditions such as heart or lung disease, poor exercise tolerance, or impaired muscle function. If your CPET results are abnormal, we’ll recommend further testing or treatments to address the underlying cause and work with you to improve your exercise capacity and overall health.
Lexiscan Stress Testing
- For patients who are unable to exercise due to physical limitations, we offer Lexiscan Stress Testing. This is a pharmacological stress test that uses a medication called Lexiscan (regadenoson) to simulate the effects of exercise on your heart.
What Happens During a Lexiscan Stress Testing?
- Lexiscan is injected into your bloodstream, causing your coronary arteries to dilate as they would during physical exercise.
- We monitor your heart's response to the medication, which can reveal blockages or reduced blood flow to the heart.
- This test is especially beneficial for patients with mobility issues or those who cannot tolerate traditional exercise-based stress tests. Lexiscan provides a safe and effective way to evaluate coronary artery function and detect potential issues with heart health.

Results and Next Procedure
What Do Normal Lexiscan Stress Test Results Mean?
Normal Lexiscan stress test results indicate that your heart has normal blood flow and there are no significant blockages in your coronary arteries. This suggests your heart is functioning well even under simulated stress.
What Happens if My Lexiscan Stress Test Results are Abnormal?
Abnormal Lexiscan stress test results could signal reduced blood flow to parts of the heart, which may indicate coronary artery disease or other heart conditions. Based on the results, we may recommend additional tests, lifestyle adjustments, medications, or procedures such as angioplasty or stent placement to improve blood flow and heart health.
Stress Echocardiography
- Stress Echocardiography, or Stress Echo, combines traditional stress testing with an echocardiogram (ultrasound of the heart). This test assesses how well your heart’s chambers and valves function under stress and evaluates your heart’s ability to pump blood.
- Stress Echo is excellent for detecting heart disease, valvular heart issues, and identifying regions of the heart that may not be receiving adequate blood flow. It is non-invasive and provides real-time images of your heart’s function during stress.
What Happens During a Stress Echocardiogram?
- A Stress Echo combines a traditional stress test with an echocardiogram (an ultrasound of the heart). First, an echocardiogram is taken while you’re at rest to capture baseline images of your heart. Then, you’ll undergo either an exercise or Lexiscan-induced stress test. Once your heart is stressed, another echocardiogram is performed to capture images of your heart’s function under strain, helping detect any blood flow issues or heart muscle damage.
