WebNov 3, 2024 · OVERVIEW. Contractility = the change in force generated independent of preload. Inotropy and contractility are essential synonymous — inotropes are agents that increase contractility. the slope of the end-systolic pressure volume relationship (ESPVR) curve indicates the maximum rate of force development by the ventricle. WebDrugs – inotropic agents, digoxin, calcium ions (Ca 2+) Metabolic – hyperthermia, hypercalcaemia. Heart rate – as heart rate increases (e.g., during exercise), contractility increases (this occurs up to a certain point beyond which the tachycardia impairs normal cardiac function). This phenomenon is known as the Treppe or Bowditch effect.
