elektrokardiográfiával

Elektrokardiográfiával, often abbreviated as EKG or ECG, is a non-invasive medical diagnostic technique used to record the electrical activity of the heart over a period of time. This electrical activity is detected by electrodes placed on the skin of the chest, arms, and legs. The resulting recording, an electrocardiogram, is a graph that shows the fluctuations in electrical potential. It is a fundamental tool in cardiology for assessing heart rate and rhythm, detecting abnormalities in heart muscle function, and diagnosing various cardiac conditions.

The procedure itself is painless and quick. Electrodes, typically small adhesive pads, are attached to specific locations on the patient's body. These electrodes are connected by wires to a machine that amplifies the heart's electrical signals and displays them as a tracing on a screen or paper. The tracing consists of waves and complexes, each representing a specific electrical event within the heart, such as atrial depolarization (P wave), ventricular depolarization (QRS complex), and ventricular repolarization (T wave).

Doctors analyze the pattern, duration, and amplitude of these waves to identify potential problems. Abnormalities can indicate conditions like arrhythmias (irregular heartbeats), myocardial infarction (heart attack), hypertrophy (enlargement of heart chambers), or electrolyte imbalances. While EKG is a powerful diagnostic tool, it is often used in conjunction with other tests for a comprehensive evaluation of heart health.
