What is the exertion test?
Exercise stress test or cycloergometry is a non-invasive cardiological test where the subject’s cardiovascular system is put under strain on a stationary bicycle. Cycloergometry is used to assess risk and diagnose heart disease in active athletes, as well as to assess the work ability of cardiac patients.

Which conditions are monitored and diagnosed with an exertion test?
Exertion testing is most often used to address the possible atherosclerosis of the heart vessels and subsequent coronary heart disease, which manifests itself in angina pectoris; namely, for many patients with early stage disease, angina pectoris only presents itself during exertion.
Which conditions are monitored and diagnosed with an exertion test?
Angina pectoris is the leading symptom of heart disease. It manifests as a pressing or tingling pain behind the sternum, spreading to the left shoulder or arm, or as a squeezing pain in the xiphoid or neck. Such pain occurs with physical exertion and disappears when exertion subsides. Exertion testing also aims to identify a possible excess increase in blood pressure under load as well as an abnormal heart rhythm. Cycloergometry is used to assess the impact of drugs used for the treatment of high blood pressure or coronary artery disease, as well as to assess the degree of exertion that may be placed on the heart after a heart attack or cardiac surgery.

How is the exertion test conducted?
At the start of the cardiac exertion test, ECG electrodes are placed on your chest. At rest on the bike, we record an ECG and measure the blood pressure. Based on the measured values, the doctor decides whether to proceed with the test.
How is the exertion test conducted?
The bicycle exertion test is suitable for subjects who have difficulty walking. While on the bicycle, subjects also do not move their upper bodies as much, which makes it easier to measure the BP and provide for a higher quality ECG. Subjects can chose between a ramp test or a continuous load increase test. The exertion starts with 2-minute intervals which increase either gradually or continuously. Each individual exertion session lasts for a total of 6 to 12 minutes, followed by a short resting period. During the cardiac exertion test, ECG is continuously recorded and blood pressure is measured at every stage. The cardiac exertion test is completed when the subject reaches his or her maximum pulse or if the subject cannot continue due to high blood pressure, muscle pain, ECG rhythm disturbances, pain behind the sternum, nausea, dizziness, fatigue, or if the subject is unable to continue the test for any other reason. After the exertion is completed, i.e, during the rest phase, the subject remains on the bike for another 6 minutes. During the rest phase, the ECG and blood pressure are still being measured. During the rest phase and for 5 minutes after the end of the exertion test, the patient’s appearance and symptoms are also monitored.
What to know before starting exertion testing?
What to know before starting exertion testing?
Exertion testing is conducted by a cardiologist and a trained nurse. Before the cardiac exertion test, each subject is described the procedure. The subject puts on trainers and sweat pants. They are not to consume food, alcohol, coffee and to avoid smoking for 3 hours before the test.
What to know before starting exertion testing?
They are not to consume food, alcohol, coffee and to avoid smoking for 3 hours before the test. Next, the medical history is checked, a clinical examination concluded in order to rule out any contraindications to commence cardiac stress testing. Before the examination, the subject is asked to fill in the examination consent form and a questionnaire, indicating any potential health issues.
