摘要: In order to work as a pump, the cardiac muscle has be able contract and relax with velocity which is adapted circulatory system of actual species. The factors that limit rate are therefore function time periods necessary for contraction relaxation. evolutionary process created meaningful upper limits highest possible heart any given species can reach during physiological conditions. mechanism puts increase slow repolarization myocardial muscle.
