Reply to comment by IFNy in considering the stomach is highly vascular, does the use of blood thinners and/or beta blockers affect digestion? by Livid-Rutabaga
Not to be pedantic but if someone is take a beta blocker for atrial fibrillation it will increase cardiac output despite the reduction in heart rate. Actually most people who take a beta blocker probably have an increase in CO due to higher stroke volume. Only for those who take it for sinus tachycardia would have a deceased in CO.

CO = EF x HR so what you’re discussing is that they will increase EF with increased end diastolic pressures but decreased HR will ultimately shift the equation to a lower cardiac output

CO = Stroke volume x hr. It's a fine balance. If someone is in af with fvr then stroke volume will be low because of decreased preload (as there won't be as much time for ventricles to fill) therefore slowing hr will allow more filling and increased sv and ultimately co.

No CO = SV x HR. EF = (SV/EDV)/100. Please tell me more about how CHF patients take beta blockers to decrease the CO though /s
