Does the right atrial waveform pattern determine hemodynamic compromise in patients with severe right ventricular infarction?
Population
16 patients with hemodynamically severe acute right ventricular (RV) infarction
Comparison

RA W pattern linked to better hemodynamics in RV infarction; hypothesis-generating and does not yet support practice change.
Does the right atrial waveform pattern determine hemodynamic compromise in patients with severe right ventricular infarction?
The amplitude of the right atrial A wave is an important determinant of right ventricular performance and hemodynamic compromise in patients with acute right ventricular infarction.
Goldstein et al. (1990) studied this question.
