Do abnormal heart rhythms decrease blood delivery?

In brief: Depends

It depends on the type of dysrhythmia and the rate.
For example, atrial fibrillation with a heart rate in the 70-80s may cause no symptoms at all. A rate in the 150's may decrease blood pressure because there is not adequate time for the heart to fill between beats. A heart rate lower than 30 may cause a low blood pressure because the slow rate. Symptoms often relate to total cardiac output.

I agree with Dr. Fenster. Furthermore, abnormal heart rhythms originating in the lower chamber (most abnormal rhythms are in the top chamber) are fundamentally inefficient beats for pumping blood. These very frequently result in low blood pressures and can cause loss of consciousness.

In brief: Potentially

The pumping of the heart is the mechanism by which blood is delivered throughout the body.
If a abnormal heart rhythm affect what is known as the cardiac output, it can definitely affect the delivery of blood throughout the body. Thank you for the question.
