Fig 1 The skeletal muscle ventricle (SMV) aortic counterpulsator model. (ECG = electrocardiogram; PTFE = polytetrafluoroethylene.) The Annals of Thoracic Surgery 2002 73, 588-593DOI: (10.1016/S0003-4975(01)03458-0)
Fig. 2 Electrocardiographic (ECG), aortic pressure, and aortic root flow tracings from a typical dog after 7 weeks of rapid ventricular pacing). Conventional timing (A), and delayed contraction (B). Note the decrease in pre-systolic pressure, however with no effect on aortic root flow with the conventional timing.

Fig 3 Electrocardiographic (ECG) and coronary blood flow (from the left anterior descending artery) tracings in a dog after 7 weeks of rapid ventricular pacing. Conventional timing (A), and delayed contraction (B). Note the reversal of coronary blood flow with the conventional timing (arrow).
