electrocardiografie

Electrocardiography (ECG or EKG) is a diagnostic tool used to record the electrical activity of the heart. It is a non-invasive procedure that involves placing electrodes on the skin to detect the electrical signals produced by the heart's muscle cells. These signals are then amplified and displayed on a monitor or printed on paper, creating a graphical representation known as an electrocardiogram.

The ECG provides valuable information about the heart's rhythm and electrical activity. It can help diagnose various cardiac conditions, including arrhythmias, myocardial infarction, and heart block. The ECG is commonly used in clinical settings, including hospitals, clinics, and emergency departments, to assess heart health and guide treatment decisions.

The ECG is typically performed in a quiet, comfortable environment. The electrodes are placed on specific locations on the body, such as the arms, legs, and chest. The recording process usually takes a few minutes, and the results are immediately available for interpretation. The ECG is a safe and painless procedure that does not require any special preparation.

Interpreting an ECG involves analyzing the waveform patterns and intervals. Key components of an ECG include the P wave, QRS complex, and T wave, which represent different stages of the heart's electrical activity. Abnormalities in these components can indicate underlying heart conditions. ECG results are often used in conjunction with other diagnostic tests and clinical findings to make a comprehensive assessment of the heart's health.
