Overview

Laboratory Studies

The diagnosis of right ventricular infarction is suspected in the appropriate clinical setting when the right atrial pressure exceeds 10 mmHg and the ratio of right atrial pressure to pulmonary capillary wedge pressure exceeds 0.8 (normal mean value less than 0.6)[1] [2] [3] [4] [5].

However, these findings may not be present in patients with only minimal right ventricular dysfunction or in those with intravascular volume depletion. In the latter setting, a volume challenge may unmask the signs of right ventricular infarction [6]
