One of the factors that make muscles contract is the release of calcium onto the muscle fibers. An electrical signal is sent into the muscle and stimulates the sarcoplasmic reticulum to release calcium along the muscle. A calcium channel blocker may reduce the muscle's contact with calcium and could possible explain why the heart has lower output.

How does a beta blocker help tachycardia?
Reduces the work load and increases cardiac output
Amount of blood pumped by the heart in 1 min?
cardiac output :)
Determined by heart rate x stroke volume?
cardiac output
If resting cardiac output is six liters and maximum exercise cardiac output is sixteen liters what is the cardiac reserve?
10 liters
How much blood returns to the heart?
cardiac output
Which statement is correct about cardiac output?
cardiac output is heart rate multiplied by stroke volume,
What is resting cardiac output?
its not cardiac rest, its cardiac ARREST. which is a heart attack.
What is the medication supplied for Toprol-XL?
Toprol-XL is a trade name for metoprolol succinate, an antihypertensive beta-blocker. It blocks sympathetic response (fight or flight) in the CNS, reducing BP and cardiac output.
What is cardiac-output?
Cardiac output is the volume of blood the heart pumps within one minute. Cardiac output (CO) is equal to the stroke volume (SV) of the heart multiplied by the heart rate (HR). Thus, cardiac output is given by the equation: CO=HR X SV.
Does exercise Change in cardiac output or in peripheral resistance?
Both, peripheral resistance decreases and cardiac output increases.
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
What is the effect of cardiovascular excerise on cardiac output?
Cardiac output is the total volume of blood that is pumped by the heart per minute. When you exercise, there is a greater demand for oxygen, which is carried in your blood, thus your cardiac output increases.
