Comparison of the septal contribution to LV stroke volume for patients with MI in the LAD and RCA vessel territories and controls. Septal contribution to SV was significantly lower for the LAD-MI compared to both RCA-MI and controls. There was, however, no significant difference between RCA-MI and controls. Negative values of septal contribution are explained by dyskinesia of the septum, i.e. septal movement toward the RV in systole. Solid line indicates the mean. *P < 0.05, **P < 0.01 NS non-significant
