The heart is one of the most important organs in the human body. It supplies oxygen and nutrients to the whole body through continuous contraction and relaxation. Knowing how your heart is working is critical to assessing heart health. As a commonly used diagnostic tool, electrocardiogram (ECG) can provide key information to help doctors evaluate the movement of the heart.
ECG charts assess how the heart is moving by recording the electrical signals produced by the heart's electrical activity. When the heart contracts, electrical signals propagate through the heart tissue, forming a specific waveform; when the heart relaxes, the electrical signals change. Waveforms such as P wave, QRS wave group and T wave on the electrocardiogram reflect the electrical activity of the heart in different stages.
1. Heart rhythm assessment: Electrocardiograms can help doctors detect whether the heart rhythm is regular, such as arrhythmia, etc. By analyzing parameters such as the time interval, shape, and frequency of P waves and QRS complexes, doctors can determine whether there is an abnormal rhythm in the heart and thereby evaluate cardiac movement.
2. Myocardial ischemia assessment: Myocardial ischemia is a condition in which the heart muscle does not receive enough oxygen due to insufficient blood supply from the coronary arteries. Electrocardiograms can detect specific changes caused by myocardial ischemia, such as elevation or depression of the ST segment. These changes reflect the movement of the heart during myocardial ischemia and help doctors determine whether the patient has coronary heart disease or other heart diseases.
3. Ventricular hypertrophy assessment: ECG can detect ventricular wall hypertrophy. When ventricular wall hypertrophy occurs, the electrical signal of the heart changes, manifested as widening and increased amplitude of the QRS complex. By analyzing the QRS waveform on the electrocardiogram, doctors can evaluate the degree of ventricular hypertrophy and then determine the movement and functional status of the heart.
4. Heart damage assessment: EKG can detect heart damage, such as myocardial infarction. Changes in electrical signals caused by heart damage, such as elevation or depression of the ST segment and the appearance of Q waves, can be evaluated through electrocardiograms to help doctors determine the degree and location of heart damage.
An EKG is a simple yet effective tool for assessing the movement of the heart. By analyzing the waveform changes on the electrocardiogram, doctors can determine whether the heart has abnormal rhythm, myocardial ischemia, ventricular hypertrophy, heart damage and other problems. This information is critical for assessing heart health and developing an individualized treatment plan. Therefore, in heart health care, the application of electrocardiograms is indispensable and can help us better understand and pay attention to our own heart health.
