kardiografii
Kardiografi is a medical term referring to the recording of the electrical activity of the heart. This process is more commonly known as an electrocardiogram (ECG or EKG). A kardiograf, or electrocardiograph, is the instrument used to perform this recording. It detects and amplifies the tiny electrical impulses generated by the heart muscle as it contracts and relaxes. These electrical signals are then displayed as a series of waves and lines on a graph or screen, providing a visual representation of the heart's rhythm and electrical conduction. The typical waves observed are the P wave, QRS complex, and T wave, each corresponding to specific electrical events in the cardiac cycle. Kardiography is a non-invasive and painless procedure, typically performed by placing electrodes on the skin of the chest, arms, and legs. The resulting recording helps physicians diagnose a wide range of cardiac conditions, including arrhythmias, myocardial infarction (heart attack), heart chamber enlargement, and conduction abnormalities. It is a fundamental diagnostic tool in cardiology and is widely used in hospitals, clinics, and even in emergency settings.
