RV compression ≤7 mm may aid tamponade diagnosis in effusion; leaves open prospective validation before changing practice.
Does echocardiographic right ventricular compression identify cardiac tamponade in patients with pericardial effusion?
Right ventricular compression on echocardiography is a useful and specific sign for diagnosing and monitoring cardiac tamponade in patients with pericardial effusion.
Schiller et al. (1977) studied this question.
