rasituskykytesti

A rasituskykytesti, often translated as a stress test or exercise tolerance test, is a medical examination used to assess how the heart functions during physical exertion. It is typically performed on a treadmill or stationary bicycle. During the test, the patient's heart rate, blood pressure, and electrocardiogram (ECG) are monitored continuously as the intensity of the exercise gradually increases.

The primary purpose of a rasituskykytesti is to detect or evaluate coronary artery disease. Blockages in the coronary arteries can limit blood flow to the heart muscle, especially when it is working harder. Symptoms like chest pain (angina), shortness of breath, or arrhythmias that occur during exercise may indicate such problems. The test helps doctors determine the presence and severity of these issues, as well as assess the heart's overall capacity to handle increased demands.

The test is usually conducted under the supervision of a cardiologist or trained medical professional. The patient is asked to report any symptoms they experience during the test. The exercise is stopped when the patient reaches a target heart rate, experiences significant symptoms, or shows abnormal changes on the ECG. The results help guide treatment decisions, including medication, lifestyle changes, or further diagnostic procedures. Contraindications for the test include recent heart attack, unstable angina, or certain arrhythmias.
