The main manifestation of abnormal ECG is that it presents waveforms or rhythms that are different from normal conditions, and these abnormalities may prompt doctors about the patient’s heart health issues. The following are some typical ECG abnormalities：
Atrial fibrillation: When atrial fibrillation occurs, ECG images typically display fast, irregular, without significant P-waves and multiple small oscillations of QRS waves.
Ventricular fibrillation: On ECG, ventricular fibrillation typically manifests as oscillations between high frequencies (>300 beats/minute) and irregular intervals, without significant QRS waves.
Left deviation of the electrocardiogram axis: When some tissues in the human body are damaged, resulting in a large number of muscle fiber deaths and other problems, it can cause lateral disorders. ECG can detect this impact and display it as a decrease in R to S values in SR mode and tilt to the left.
ST-T changes: ST-T changes can indicate the presence of coronary artery disease or other vascular diseases in patients. In such cases, phenomena such as ST segment elevation or depression and T-wave inversion can be observed in ECG.
The above are some common ECG abnormalities, but the specific manifestations may vary depending on individual circumstances. If you have any heart health issues, please consult a professional doctor.
