Abnormal ECG usually refers to the manifestation of various physiologic or pathologic factors that result in ECG measurements that are inconsistent with normal standards.
1. Abnormalities in heart rate, rhythm or conduction velocity may also occur under physiological conditions, such as strenuous exercise, emotional stress and pregnancy, which may also lead to abnormal ECG.
2. Of course, abnormal ECG is more common in cardiovascular diseases, which can be clinically manifested as various types of arrhythmia, and then abnormal ECG can be found in ECG examination, which can be manifested as abnormal changes in P-wave, QRS-wave, T-wave and other parts of the ECG.
Once abnormalities in ECG are detected, it is necessary to go to the hospital in time for examination to clarify the cause of the disease.
