Arrhythmia is also relatively common in clinical practice, and its common detection method is mainly the electrocardiogram (ECG). ECG is a simple and non-invasive operation that helps to identify the type of arrhythmia. Another method is the 24-hour Holter monitor, which can record all heart rate changes occurring within 24 hours. If an arrhythmia occurs, it is crucial to seek medical attention promptly, visiting a cardiology department. Treatment may involve antiarrhythmic medications, and if possible, a complete electrophysiological examination can be performed.
