Abstract: The orderly contraction of the vertebrate heart is determined by generation and propagation of cardiac action potentials(APs). APs are generated by the integrated activity of time- and voltage-dependent ionic channels which carry inward Na+ and… read more here.

Abstract: Bird cardiomyocytes are long, thin and lack transverse (t)-tubules, which is akin to the cardiomyocyte morphology of ectothermic non-avian reptiles, who are typified by low maximum heart rates and low pressure development. However, birds can… read more here.
