Purpose and Procedure of the Exercise ECG Stress Test

The exercise ECG stress test is a meaningful way to diagnose heart problems and understand how well your cardiovascular system works. When you come to WELL Health Diagnostic Centres, we can provide comprehensive exercise ECG stress tests to assess the performance of your heart during physical strain. This blog post will help you learn about what an exercise stress test entails, why it’s done, what information it can give us regarding your heart health, and the best ways to prepare yourself beforehand.

What is an Exercise Stress Test?

According to the American Heart Association, an exercise stress test, also known as an exercise ECG stress test or treadmill test, is one of the best ways to assess and track the health of your heart. It is a process designed to check the activity of your heart while you do physical exercise, like walking on a treadmill or riding a stationary bike. During this test, we monitor your heart rate, blood pressure, and electrical movement (using an electrocardiogram or ECG). All of these things are observed continuously as you increase the amount of physical effort during the exam.

The first step is fixing electrodes on your chest, which are linked to the ECG machine. You begin exercising slowly, and then increasing in speed and intensity. This process aims to make your heart work harder and pump out more blood, resembling how your heart responds when doing physical activities.

What is the Purpose of Exercise Stress Tests?

The main reason for an exercise stress test is to check how well your heart and blood vessels work during physical activity. This test can assist in finding out many vital factors about the health of your heart:

Heart Function Evaluation: The exercise ECG stress test is beneficial in assessing your heart’s ability to tolerate physical exertion and if there are enough blood supplies during times of heightened demand.

Diagnosing Coronary Artery Disease (CAD): The test can detect signs of CAD, which occurs when the arteries that bring blood to the heart muscle become narrow or blocked. It does this by checking how the heart reacts during exercise.

Symptoms Evaluation: When you have chest pain, feel short of breath, or get dizzy while exercising, this test can help determine whether this is linked to heart problems.

Heart Conditions Monitoring: An exercise stress test is useful for people with heart conditions or who have had heart surgery. It helps them determine how well their hearts function and whether the treatment process works as it should.

Guiding Treatment: The test’s outcomes can support doctors in creating or modifying treatment programs for heart conditions. This might mean considering whether medications are required, altering one’s way of life, and planning additional interventions.

What Does the Cardiac Stress Test Show?

The cardiac stress test offers a useful understanding of how well your heart functions and can disclose different crucial aspects related to cardiovascular fitness:

Heart Rate and Rhythm: The ECG records the electrical activity of your heart, displaying any irregularities in heart rate or rhythm during exercise.

Blood Pressure Reaction: Monitoring blood pressure during the test assists in evaluating how the cardiovascular system handles the extra physical activity requirements.

Oxygen Supply and Blood Flow: This test can show places where the heart muscle gets less blood supply. This might suggest blockages in coronary arteries.

Physical Capacity: This test gauges the amount of exercise you can do without feeling symptoms such as tiredness, chest discomfort, or difficulty breathing. It measures your general cardiovascular fitness level.

Recovery Time: The speed at which your heart rate and blood pressure return to their usual state after exercise also provides more details about your heart’s effectiveness and condition.

Understanding the information the cardiac stress test provides helps healthcare providers focus on particular areas of concern and create treatment strategies that can efficiently deal with those problems.

According to the Mayo Clinic, exercise ECGs show much more than just heart issues. A study showed that abnormalities revealed by the test can even identify problems related to non-cardiovascular disorders such as cancer. 

Cardiac Stress Test Preparation

Proper readiness is crucial to guarantee correct outcomes from your exercise ECG stress test. Here is how you should prepare:

Clothing and Footwear: Wear comfortable, loose clothes and athletic shoes for exercise. Do not wear tight or constraining clothing that could create issues when putting the electrodes or your movement.

Medicines: Follow your doctor’s instructions regarding medicines. Some might need to be stopped for a while before the test, but never stop any medicine without first asking your healthcare provider.

Food and Drink: Stay away from heavy meals or caffeine for a minimum of two hours before the test. They might create changes in your heart rate and blood pressure measurements.

Smoking and Drinking: Do not smoke or drink alcohol on the day of the test, as these can affect both your heart health and the results of the examination.

Sleep: Make sure to sleep well the night before the test. It will help you perform better and place less stress on your heart.

Discuss Symptoms: You should talk to your healthcare provider about any changes in your health that have occurred recently, like new symptoms or alterations to existing conditions.

These cardiac stress test preparation suggestions can help you accurately represent your heart’s reaction to physical activity.
