Hi greatone100-ga, The answer to your question is (D) All. Oxygen demand in the heart is increased by: -Contractility. -Heart rate. -Preload and Afterload. Works Cited: "Management of ACS in the 90s -- Basics of Treatment" http://www.umanitoba.ca/faculties/medicine/units/emergency_medicine/archive/coronary/coronary_syn2.htm Search Strategy: Searched in Google using the following terms: "oxygen demand" heart preload I then used Dictionary.com to find the definition of the word myocardial, which is defined as "The muscular tissue of the heart." I hope this information is of assistance to you. If you need any addition clarification please let me know. -rmn-ga |
