View larger version (29K): [in a new window]   Figure 1 Representative pressure–dimension curves before (top) and after (bottom) pacing-induced heart failure in the baseline state (squares) and after nitroprusside (circles) and dobutamine (triangles). A shift of the pressure–dimension relation with nitroprusside and dobutamine occurred only after heart failure was produced.
