The antonyms for the term "right ventricular function" could be poor, weakened, impaired, or dysfunctional. When the right ventricle is unable to contract or relax properly, it can lead to a variety of cardiac diseases and disorders, such as pulmonary hypertension, heart failure, or arrhythmias. Therefore, assessing and monitoring the right ventricular function is crucial in diagnosing and managing these conditions. However, in some cases, the right ventricular function may be normal or even enhanced, such as during physical exercise or in response to certain medications. Therefore, it is important to understand the context and underlying factors affecting the right ventricular function when interpreting the antonyms of this term.
