Question

an increase in heart rate would ____________ cardiac output.
a decrease
b increase

Explanation:

Cardiac output is calculated by the formula \(CO = HR\times SV\) (where \(CO\) is cardiac output, \(HR\) is heart rate, and \(SV\) is stroke volume). Assuming stroke volume remains constant or changes in a non - offsetting way, an increase in heart rate (\(HR\)) would lead to an increase in cardiac output (\(CO\)).

Answer:

B. increase
