Would an increase in contractility cause an increase to cardiac output?

Yes - an increase in contractility would lead to an increase in stroke volume. An increased stroke volume would cause an increased cardiac output.

What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
Is Cardiac output equal on both sides of heart?
Yes, it must be so in a healthy heart. The reason is very simple. The left and right ventricles pump in the same cycle (and, if this were not the case, there would be a backlog of fluid in one system or the other).
What organ in the body has specialized cells that work together to form cardiac muscle tissue?
Answer for anyone looking is the fact that the cardiac muscle never stops, it cannot, otherwise you would die.
Cardiac mass icd 9 code?
Without any further information about the nature of the mass, the ICD 9 code to use for a cardiac mass would be 429.89.
Why would urine output be increased after surgery?
IV fluids.
What decreases cardiac output without change in heart rate PAWP or SVR Is it preload afterload or contractility?
A change in cardiac output without any change in the heart rate, pulmonary artery wedge pressure (PAWP = equated to preload) or systemic vascular resistance (SVR = afterload) would have to be due to a change in the contractility of the heart. Cardiac output (CO) is roughly equal to stroke volume x heart rate. Stroke volume is related to preload, contractility, and afterload. As you can see, the only variables you have not controlled for is cardiac contractility.
Which of the following would have a negative impact on cardiac contractility?
Norepinephrine
What effect does stimulation of the acetylcholine receptors of the heart have on cardiac output?
The effect would be an increase in cardiac output. However, there is a maximum level and then the heart would not have time to fill fully and the output would decrease.

The effect would be an increase in cardiac output. However, there is a maximum level and then the heart would not have time to fill fully and the output would decrease.
What effect would compressing the inferior vena cava just below the diaphragm have on cardiac function?
Cardiac output would decrease, SV would also decrease, the heart rate would then increase and sympathetic stimulation of the heart would also increase.
Does cardiac output affect urine output?
Certainly. Decrease cardiac output would mean a decreased in blood flow to the kidneys, which would lead to reduced filtration, therefore urine output.
What would happen to cardiac output if the stroke volume increased and the heart rate stayed the same?
Since the stroke volume increased then the cardiac out put would increase, pumping out more blood with the same amount of heart beats.
How would acute coronary syndrome effect cardiac output?
I will decrease cardia output
How would a decrease in blood volume affect both stroke volume and cardiac output?
It's decreased ... unless the rate falls, which is the normal cardiac response.
How would a weak heart affect the movement of blood through the body?
At rest, not at all. BUT there would be less of an increase in cardiac output during exertion - which results in quick fatigue and lowered (maximum) activity.
How would severe bleeding from a major veins affect heart rate and heart output?
Your cardiac output is equal to your stroke volume (amount of blood being pushed out every time your heart beats) multiplied by your heart rate. Your cardiac output equals the amount of circulating blood needed to function at a given time.Your body will try to compensate for any changes in the amount of blood in your system, therefore your body will always try to maintian cardiac output. With any type of major bleeding, your stroke volume will decrease. In order to maintain your cardiac output, your heart rate will increase. For example:(Stroke Volume of 50mL) x (Heart Rate of 60) = Cardiac Output of 300With major bleeding, the decrease in stroke volume will require an increase in heart rate:(Stroke Volume of 25mL) x (Heart Rate of 120) = Cardiac Output of 300You can see that the amount of blood decreased in half for every heart beat (50mL to 25mL), so the heart has to beat twice as fast (60 beats per minute to 120 beats per minute) to make up for the blood loss.
Which of the following would cause the greatest increase in cardiac output?
Increased heart rate and increased stroke volume
