However, an incomplete block generally does not pose a risk on its own. Its reversibility . Answer only. Although the ST-T wave changes in the inferior leads of the tracing seen here may indeed reflect right-sided "strain" (from RVH), it is important to emphasize that these changes could also reflect ischemia. This is because the electrocardiogram represents a balance of electrical forces between the left and right ventricles at any given instant in time. However, in some people, right bundle branch block is just one manifestation of a more general problem with the hearts electrical conduction system. Risk factors for pulmonary embolism are read more (submassive or massive) may cause acute right ventricle overload or failure, which manifests classically (but not commonly) as right axis deviation (R > S in V1), with S-wave deepening in lead I, Q-wave deepening in lead III, and ST-segment elevation and T-wave inversion in lead III and the precordial leads (S1Q3T3 pattern). Electrocardiography (ECG) is a useful adjunct to other pulmonary tests because it provides information about the right side of the heart and therefore pulmonary disorders such as chronic pulmonary hypertension and pulmonary embolism.
