Can temperature-dependent changes in myocardial contractility explain why fish only increase heart rate when exposed to acute warming?

Fish increase heart rate (f(H)), not stroke volume (V(S)), when acutely warmed as a way to increase cardiac output (Q). To assess whether aspects of myocardial function may have some basis in determining temperature-dependent cardiac performance, we measured work and power (shortening, lengthening a...
