In echocardiography stress testing, also called stress echocardiogram or simply stress echo, the heart is examined during physical activity to determine how well it functions. In order to assess how well the heart muscles and valves are performing under stress conditions, echocardiography, a non-invasive imaging technique that creates images of the heart using sound waves, is combined with exercise or medication-induced stress.
Before undergoing an echocardiography stress test:
The patient consults with their healthcare provider to discuss the reasons for the test and what to expect during the procedure.
Patients may need to fast before the test, depending on the instructions provided by their healthcare provider.
Certain medications may need to be temporarily discontinued before the test, especially if they affect blood pressure or heart rate.
During the echocardiography stress test:
Before stress is induced, a baseline echocardiogram is performed to obtain images of the heart at rest. These images are used to compare how the heart functions during stress.
Exercise or medication administration: Exercise, such as walking on a treadmill or riding a stationary bike, or medication that simulates the effects of exercise, induce stress.
Healthcare personnel closely monitor the patient's heart rate, blood pressure, and symptoms throughout the test.
To assess how the heart responds to increased workload, additional echocardiogram images are obtained during and immediately after stress is induced.
After the echocardiography stress test:
After the test, patients may be monitored for a short period to ensure that their heart rate and blood pressure return to baseline.
Unless otherwise instructed by their healthcare provider, patients can usually resume normal activities immediately after the test.
Echocardiography stress tests are generally safe, but there are some potential risks, including:
Stress can sometimes cause irregular heartbeats or arrhythmias. Healthcare providers are trained to monitor and manage these situations.
Exercise or medication-induced stress can cause fluctuations in blood pressure, resulting in dizziness and fainting.
Following an echocardiography stress test:
Drink plenty of fluids to stay hydrated, especially if you fasted before the test.
Patients can usually resume any medications they temporarily discontinued before the test, unless their healthcare provider instructs them otherwise.
Depending on the results of the test, patients may need further evaluation or treatment. Follow-up appointments with the healthcare provider are scheduled to discuss the findings.
Echocardiography stress tests can be helpful in detecting abnormalities that may not be apparent at rest when assessing heart function. Healthcare providers can evaluate cardiovascular health and make informed decisions regarding patient care using this test, which provides real-time images of the heart during stress.
