Final answer:
Patients with aortic stenosis and atrial fibrillation will have higher peak systolic aortic velocity following short R-R intervals.
Step-by-step explanation:
In patients with aortic stenosis and atrial fibrillation, the peak systolic aortic velocity will be higher following short R-R intervals.
In atrial fibrillation, the electrical pattern is abnormal, with no consistent P waves. Instead, there are irregular, erratic electrical signals.
The irregularity in the electrical signals can lead to irregular ventricular contractions.
In atrial fibrillation, the R-R intervals are irregular and can vary in length.
During short R-R intervals, the ventricles have less time to fill with blood, resulting in faster and more forceful contractions.
This leads to higher peak systolic aortic velocity.
