: Your Patient S End Diastolic Volume Is 110 Ml Her End Systolic Volume Is 40 Ml Her Heart Rate Is 75 Beats Per Minute 1 (23.65 KiB) Viewed 32 times

: Your Patient S End Diastolic Volume Is 110 Ml Her End Systolic Volume Is 40 Ml Her Heart Rate Is 75 Beats Per Minute 2 (25.76 KiB) Viewed 32 times

Your patient's end diastolic volume is 110 mL: her end systolic volume is 40 ml. Her heart rate is 75 beats per minute. All of these are true except: Her stroke volume is 70 mL/beat. Her cardiac output is 5.25 L/min. These are relatively normal numbers and do not indicate that she has heart failure. These signs are indicative of HFrEF due to dysfunction of the left ventricle. Her ejection fraction is 64%.
All of the following are good matches between a drug class and function or effect except: cardiac glycosides: decrease intracellular calcium so decreased contractility and output Ca** channel blockers: decrease intracellular calcium so decreased contractility and output B NE R blockers: decrease intracellular calcium so decreased HR, contractility and output catecholamines: stimulate NE R and increase HR, contractility and output anti-cholinergics: increase heart rate and cardiac output
