Hemodynamic, composite ACC and ANGV signals recorded from a sensor (animal 10, RVa). ECG, LV and aortic pressures are displayed in the upper panel. The vertical line crossing all three panels is aligned with the R wave of the second ECG complex. The middle panel displays the composite systolic and diastolic ACC signals (dotted and dashed ellipses, respectively). The lower panel displays the composite systolic and diastolic ANGV signals (dotted and dashed boxes, respectively). Filters were not used when data were recorded to avoid phase delays. Vertical arrow points to the second P wave. Acc accelerometer, deg degrees, g kg m/s2, Gyro gyroscopic signal measuring ANGV, mmHg millimeters of mercury, PAO aortic pressure, PLV LV pressure, sec second, Tot total or composite signal
