EKGsignaaleja

EKGsignaaleja, often referred to as ECG signals or electrocardiogram signals, represent the electrical activity of the heart recorded over time. These signals are produced by the coordinated contraction and relaxation of the heart's muscle cells, which are triggered by electrical impulses. An electrocardiograph, or EKG machine, is used to detect and amplify these electrical currents. The resulting waveform is then displayed on a graph, with time on the horizontal axis and voltage on the vertical axis.

The characteristic components of an EKG signal include the P wave, QRS complex, and T wave. The P wave signifies atrial depolarization, the electrical activation of the upper chambers of the heart. The QRS complex represents ventricular depolarization, the electrical activation of the lower chambers. Finally, the T wave corresponds to ventricular repolarization, the electrical recovery of the ventricles. Abnormalities in the shape, duration, or timing of these waves can indicate various cardiac conditions, such as arrhythmias, myocardial infarction (heart attack), or hypertrophy. Analyzing EKGsignaaleja is a fundamental diagnostic tool in cardiology, providing valuable insights into the heart's function and rhythm.
