The stress test (or ergometric test)

The stress test (or ergometric test) is an instrumental examination that involves recording the electrocardiogram before, during, and after the execution of physical exercise (unlike the baseline ECG, which is recorded only under resting conditions).

This allows for the examination of the cardiovascular system’s response to physical exercise, particularly regarding heart rate, blood pressure response, and any ECG abnormalities. During physical exertion, conditions arise that increase the demands on the heart, potentially revealing abnormalities not detectable at rest.

How is the Exercise Stress Test Conducted at Arsbiomedica Clinic?

At Clinica Arsbiomedica, the stress test begins with baseline measurements of blood pressure and resting electrocardiogram. If there are no contraindications to starting the examination (symptoms, excessively high blood pressure, or ECG abnormalities evaluated by the cardiologist), the patient begins physical exertion by walking on a treadmill. The workload starts low and gradually increases until reaching a certain value of maximum heart rate for age.

The choice of workload and the rate of increase in exertion are determined by the physician based on standardized protocols and the patient’s clinical characteristics.

The test lasts approximately 20 minutes, during which a Cardiologist and a Nurse are present to monitor cardiac parameters. Attention is paid to any symptoms the patient may experience (chest pain, dizziness, shortness of breath, excessive weakness) and their relationship with any changes in the electrocardiogram and blood pressure.

The procedure can be stopped by the Cardiologist at any time based on standardized clinical and instrumental criteria, or at the patient’s request due to muscle exhaustion.

How to Prepare for the Exam?

Before the ergometric test, the patient should:

• Fast for at least 4 hours
• Avoid smoking for 12 hours
• Refrain from consuming coffee or tea for 12 hours before the examination
• Suspend, according to the physician’s instructions, certain categories of medications (especially beta-blockers, which can interfere with the correct functioning of the stimulant used and alter the test result).

It is preferable for the patient to wear comfortable and non-constricting clothing and shoes.

Additionally, the patient is required to bring relevant clinical documentation (especially a recent electrocardiogram) and current medications to the examination.
