How does heart rate change with enlarged or smaller heart? - enlarged heart more condition_symptoms,

In other words, if pumbing lower function, the heart tends pumba more blood into the body and vice vesa increase. Have you the heart still beats increase or decrease when the heart is enlarged or is restored to normal size?

If yes, is a patient taking medication for the heart beats more slowly, causing an enlarged heart accordingly? and not always when a patient takes pills for heart beats in May and then return to normal size heart with a little more human?

Thank you.
