Why can hypotension occur with relative bradycardia in ai?

Physiology. Aortic insufficiency (ai) means that the aortic valve leaks during diastole, which is the relaxation phase of the cardiac cycle. Relative bradycardia means there is a slowing of heart rate which also means a prolongation of diastole. A prolonged diastole does mean more ai which results in lower blood pressure (i.e. Hypotension).
