ECGsignaalien

ECGsignaalien, often referred to as electrocardiogram signals or ECG signals, represent the electrical activity of the heart over time. These signals are recorded by electrodes placed on the skin of the chest, arms, and legs. The electrocardiogram machine amplifies these subtle electrical impulses and displays them as a waveform on a monitor or a printed strip. Each component of the ECG waveform, such as the P wave, QRS complex, and T wave, corresponds to specific electrical events during the cardiac cycle, including atrial and ventricular depolarization and repolarization. Physicians and technicians analyze the shape, duration, and timing of these waves to assess heart rhythm, detect abnormalities, and diagnose various cardiac conditions like arrhythmias, myocardial infarction (heart attack), and heart block. The interpretation of ECGsignaalien is a fundamental skill in cardiology and provides crucial diagnostic information without requiring invasive procedures. Variations in the normal ECG pattern can indicate underlying health issues that may require further investigation or treatment.
