sidosryhmäkatsaus

Sidosryhmäkatsaus, also known as a group exercise test, is a medical procedure used to assess the function of the heart's left ventricle. It is commonly performed to evaluate the heart's ability to pump blood, particularly in patients with known or suspected cardiovascular disease.

The test involves the patient exercising on a treadmill or stationary bike while electrocardiogram (ECG) and blood pressure measurements are recorded. The goal is to induce a state of stress on the heart, similar to what occurs during physical activity, and observe how the heart responds.

During the sidosryhmäkatsaus, the patient's ECG is continuously monitored for any signs of ischemia, which is a reduction in blood supply to the heart muscle. This can manifest as ST-segment depression or elevation on the ECG. Blood pressure is also monitored to assess the heart's ability to maintain adequate perfusion during exercise.

The test is typically performed in a controlled environment with medical personnel present to ensure the patient's safety and to intervene if necessary. The duration and intensity of the exercise can be adjusted based on the patient's tolerance and the specific clinical indications.

Sidosryhmäkatsaus is a valuable tool in cardiovascular assessment, providing insights into the heart's performance under stress. It is often used to help diagnose conditions such as coronary artery disease, evaluate the effectiveness of treatments like angioplasty or bypass surgery, and assess the risk of heart disease in patients with other risk factors. However, it is important to note that the test has limitations, and its results should be interpreted in the context of the patient's overall clinical picture.
