Figure 5 Relative Change in Regional Stroke Work (Pressure-Length Loop Area) in the LV Wall

Depicted are values during left ventricular (LV) pacing before ischemia in the LV pacing preconditioning group and values during right atrial (RA) and LV pacing in early reperfusion (LV pacing postconditioning group). Dotted line represents baseline RA pacing. *p < 0.05 versus baseline RA pacing (t = 0) in same segment.
