How does an increased in cardiac fluid volume in a 26 week pregnant women affect her heart rate?
That is would it be slower, and if so why?
I thought that more fluid volume in the heart would equate to more pressure, and since the fluid can only go forward it would force the heart to pump faster. I learned this in Hurst Review. (More pressure more volume, and fluid moves forward, so I presumed the heart would need to pump faster to get out the additional blood volume, not slower)
But my reference is saying the heart rate would be slower? Could anyone explain why?
