14 Φεβ 2024 · This test can provide detailed information about the functioning of your heart and identify areas of reduced blood flow or damaged heart tissue. It is particularly useful in assessing the extent of coronary artery disease and determining the need for revascularization procedures.
30 Οκτ 2023 · In this worksheet we’ll be focusing on the arteries of the cardiovascular system, but you can test your knowledge of the veins and organs using our interactive cardiovascular system quizzes further down the page.
30 Ιουλ 2022 · Blood flow refers to the movement of blood through a vessel, tissue, or organ, and is usually expressed in terms of volume of blood per unit of time. It is initiated by the contraction of the ventricles of the heart.
Stressing the heart (by exercise or by use of stimulant medications to make the heart beat faster and more forcibly) can help identify coronary artery disease. In coronary artery disease, blood flow through the coronary arteries (which supply blood to the heart muscle) is partly or completely blocked.
18 Αυγ 2024 · Your cardiologist may recommend a more sophisticated form of stress testing, such as an echocardiogram stress test or a nuclear perfusion study, which involves a radioactive tracer injected into your vein during exercise to locate the blockage using a specialized camera.
12 Απρ 2021 · The exercise stress test uses an electrocardiogram (ECG) to record the heart's electrical activity. Changes in the ECG reading can signify blood flow abnormalities caused by blockages in the heart's arteries or other problems in the heart.
In stress testing, the heart is monitored by electrocardiography (ECG) and often imaging studies during an induced episode of increased cardiac demand so that ischemic areas potentially at risk of infarction can be identified.
