The 180 degree ECG axis represents right deviation of the electrical axis, and right deviation of the electrical axis can be seen in people with emaciation, pendulous heart, right ventricular hypertrophy, etc., which needs to be analyzed specifically. Normal adult electrocardiogram shows that the electrocardiographic axis ranges from -30 degrees to +90 degrees, and +90 degrees to 180 degrees belongs to the right deviation of the electrocardiographic axis, which occurs in more cases: 1. Normal people: for example, children, thin people, pituitary heart, etc. Usually there is no clinical significance and there is no need to be too nervous. 2. Pathological significance: it is often accompanied by some abnormalities of ECG, such as left posterior branch block, right bundle branch block, right ventricular hypertrophy, etc., which may be related to pulmonary heart disease, cardiomyopathy, etc. The symptoms can be treated promptly according to one’s own symptoms. According to their own symptoms, they can consult a doctor in time and find out the cause of the disease under the doctor’s guidance, so as to avoid delaying the disease.
