hjartarannsókn

Hjartarannsókn, also known as cardiac investigation, refers to a range of medical procedures and tests used to assess the health and function of the heart. These investigations are crucial for diagnosing, monitoring, and managing cardiovascular diseases, which are a leading cause of mortality worldwide. The specific type of hjartarannsókn employed depends on the suspected condition and the information required by the physician.

Common forms of hjartarannsókn include electrocardiography (ECG or EKG), which records the electrical activity of the heart, and echocardiography, an ultrasound of the heart that visualizes its structure and pumping function. Exercise stress testing, often performed on a treadmill, evaluates how the heart performs under physical exertion. More advanced imaging techniques may involve cardiac MRI or CT scans, providing detailed cross-sectional views of the heart.

Invasive procedures like cardiac catheterization allow direct visualization of the coronary arteries and assessment of heart chamber pressures. Blood tests can also be part of a hjartarannsókn, looking for specific markers that indicate heart damage or risk factors for heart disease. The results of these investigations guide treatment decisions, ranging from lifestyle modifications to medication or surgical interventions. Early and accurate hjartarannsókn is vital for improving patient outcomes and preventing serious cardiac events.
