Shift in Vh due to tension versus initial Vh. This plot shows that sensitivity to tension differs depending on initial Vh. Upon categorization of initial Vh with values greater than and less than − 30 mV, differences in sensitivity to tension are exposed. In those patches with initial Vh greater than − 30 mV (red symbols; − 23.0 ± 2.6 mV; 4.28 mV/mmHg; n = 3), sensitivity is nearly double that of the group with initial Vh less than − 30 (blue symbols; − 57.6 ± 5.4 mV; 2.536 mV/mmHg; n = 4). For comparison, the relationship for all average patches is shown (magenta symbols), where a sensitivity to tensions is 3.3 mV/mmHg. This latter relationship is derived from data in Fig. 7. Linear fits provide the slope sensitivity.
