Table 1.

Measured aortic blood pressure (BP; units of mmHg and represented as systolic/diastolic) and heart rate (HR; units of beats/minute). All numbers are average values determined by selecting a range of cardiac cycles that correspond to the physiologic interventions (i.e., baseline, increased preload, and increased afterload) and pumping mode (i.e., continuous and pulsed).
