NURSING 602 Module 7 Questions for Self-Study Determinants of Cardiac Output 1. Detail the determinants of cardiac output a. Heart Rate – Beats per minute. Influenced by positive (catacholamines) and negative chronotropes. i. Temperature via the Q10 effect (the factor by which the rate of a reaction increases for every 10 degree rise in temperature) will increase heart rate. The temperature effects on heart rate are mediated via increases in metabolic rate. Importantly, a heart rate of greater...
