Pharmacological ion-channel blockers were used to investigate the spontaneous heart rates in Pacific hagfish, Eptatretus stoutii. Zatebradine, a hyperpolarization-activated cyclic nucleotide-gated (HCN) channel blocker, vastly reduced atrial and ventricular contraction rates in a similar concentration-dependent manner, indicating a major role

Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have been used in many studies to assess proarrhythmic risks of chemical compounds. In those studies, field potential durations (FPD) of hiPSC-CMs have been corrected by clinically used Fridericia's and/or Bazett's formulae, however

Intrinsic regulation of the heart in teleosts is partly driven by central venous pressure, which exerts a modulatory role on stroke volume according to the well-known Frank-Starling mechanism. Although this mechanism is well understood from heart perfusion studies, less is

Hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels generate the rhythmic beating of mammalian hearts. We identified an HCN homolog in the colonial ascidian Botryllus schlosseri, a nonvertebrate chordate which possesses a tubular heart that beats bidirectionally. Contractions initiate at one end of
