When hiPSC-CMs were stimulated at a fixed frequency of 1 Hz, Iso reduced [V.sub.max] (the maximal depolarization velocity) of action potentials (APs) and shortened APD50 and ApD90 (repolarization of AP at 50 and 90%) but did not influence the RP (resting potential) and APA (amplitude of AP).
#FB [V.sub.rest] (mV) [V.sub.max] (mV) APD60 (ms) APD90 (ms) 0 -81.2 24.4 230.8 315.7 1 -79.6 23.2 210.6 320.6 4 -74.1 18.1 114.0 349.1 6 -69.2 6.5 71.6 412.6 #FB indicates the number of fibroblasts coupled myocyte, [V.sub.rest] indicates the resting potential, and [V.sub.max] is the maximum overshoot value.
[Na.sup.+]/[K.sup.+] pumps have to pump all these influx [Na.sup.+] out of membrane again to maintain resting potential and electric neutrality, so one-third of number of [Na.sup.+] is the number of ATP molecules consumed.
Resting potential of control group, MI group, and fluvastatin group ( n = 10 in each group) were −59.08 [+ or -] 7.60 mV, −64.64 [+ or -] 9.39 mV, and −61.57 [+ or -] 8.40 mV, respectively, without significant difference ( F = 1.368, P = 0.270).
Excitatory signals will cause a change in the resting potential toward the positive (depolarisation), while inhibitory signals will cause the membrane potential to become more negative and more difficult to excite (hyperpolarisation).
(9) They ascribed this difference to the relatively low transmembrane resting potential of the proximal bundle of His, similar to that in the AV node, whereas the electrophysiological properties of the distal bundle of His are similar to those in bundle branches.
Hypokalemia causes muscle weakness by lowering the resting potential of membranes, resulting in decreased excitability of neuromuscular tissue.
