Describe the relationship between stroke volume and pump rate?

The relationship between stroke volume and pump rate is that the stroke volume is inversely proportional to the pump rate. This means that as the pump rate decreases, the stroke volume increases, and vice versa. This is because the heart has a limited amount of time to fill with blood before it contracts. If the heart rate is too fast, the ventricles will not have enough time to fill completely, and the stroke volume will be reduced. Conversely, if the heart rate is slow, the ventricles will have more time to fill, and the stroke volume will be increased.
