Is the right side of the heart dangerous?

The right deviation of the ECG axis is less harmful than the left deviation of the ECG axis, and the symptoms are lighter. The right deviation of the ECG axis indicates that the right heart ECG activity produces more charge vectors, which may be related to the right ventricular hypertrophy, or the conduction block from the right atrium to the right ventricle, abnormal electrical activity, etc. Normal people may also show the right deviation of the ECG axis. The most common is pulmonary hypertension caused by lung diseases, chronic obstructive pulmonary disease, emphysema, etc., resulting in right ventricular myocardial hypertrophy. The main harm is related to the degree of right deviation. Generally, the harm is less than 110 degrees. The main manifestations are cough and wheezing in the lungs. If the degree is greater than 110 degrees, it may show systemic congestion and edema in the lower limbs. It is necessary to go to the relevant departments such as Cardiology Department and Respiratory Department for treatment, find out the cause and treat as soon as possible.
