Right axis deviation (RAD) involves the direction of depolarisation being distorted to the right (between +90 and +180). This means that there is some sort of inflammatory process occurring within the. Sometimes problems such as aortic stenosis or high blood pressure overwork the heart muscle. It is similar toleft bundle branch block (LBBB),in which the stimulation of the left ventricle is delayed. I have chronic obstructive pulmonary disease, what to do? Educational text answers on HealthTap are not intended for individual diagnosis, treatment or prescription. Suspicion for long-standing pulmonary disease (with possible RVH/pulmonary hypertension) should therefore be raised by the combined ECG findings of rightward axis, incomplete RBBB, low voltage in several precordial leads, and persistent precordial S waves in leads V4, V5, V6even in the absence of a tall R wave in lead V1 and ECG criteria for right atrial enlargement. When blood flow from the right side of the heart to the lungs is made more difficult by a blood clot in the lungs, both the right ventricle and right atrium can become enlarged.

Our All Access Subscription provides unlimited access to our entire publication (See also Electrocardiography in cardiovascular disorders.) In contrast to what occurs in children, in whom much lesser degrees of RVH are needed to produce a predominance of right-sided forces (seen on ECG as a dominant R wave in lead V1), it is only with more severe degrees of RVH and/or pulmonary hypertension that definite ECG criteria for this diagnosis are usually seen.

This thickened, stiff tissue makes it more difficult for your lungs to work properly. Other times, an abnormal ECG can signal a medical emergency, such as a myocardial infarction /heart attack or a dangerous arrhythmia.
