EKGkäyrää

EKGkäyrää, often referred to as an electrocardiogram (ECG or EKG), is a graphic record of the electrical activity of the heart. It is a non-invasive diagnostic tool used to assess the heart's rhythm and electrical conduction. The EKGkäyrää is generated by placing electrodes on the skin of the chest, arms, and legs. These electrodes detect the small electrical changes that occur as the heart muscle depolarizes and repolarizes during each heartbeat.

The resulting tracing, the EKGkäyrää, displays a series of waves, complexes, and segments. The P wave represents atrial depolarization, while the QRS complex signifies ventricular depolarization. The T wave indicates ventricular repolarization. Deviations from the normal pattern of these components can point to a variety of cardiac conditions, including arrhythmias, myocardial infarction (heart attack), hypertrophy, and conduction abnormalities.

Interpreting an EKGkäyrää requires specialized knowledge. Healthcare professionals analyze the rate, rhythm, and morphology of the tracing to diagnose or monitor heart health. It is a fundamental tool in cardiology and is routinely used in emergency settings, during stress tests, and for long-term cardiac monitoring. The information provided by an EKGkäyrää is crucial for guiding treatment decisions and understanding the overall function of the heart.
