what is normal heart function percentage

My ef is 25%, what does this mean? Can you tell me what do you mean by dilated cardiomyopathy due to rheumatic valvular heart disease? Thanks.

Cardiology


Ejection fraction is the percentage of blood in the left ventricle that is removed with each contraction. 65% is considered normal. 25 is a low number and implies a weakness of the left ventricle that is usually referred to as a Cardiomyopathy. Dilated cardiomyopathy is when the wall thins out and the ventricle gets large like a thin ballon. It can be caused by many conditions.

Stimulants


Stimulants increase the heart rate and make the heart more irritable and prone to irregular rhythms that would be perceived as palpitations. In addition to increasing the heart rate, some increase the strenght of the hear beat resulting in more blood being pumped that may cause a murmur, even in the absence of a heart defect. These stimulant may be ingested substances or internally produced.

No Easy Answers from


a distance. Everything you describe is a behavior/sign/symptom, none causal. Heart rate, strength of contraction (both heart functions) & BP (mean arteriole resistance) are all controlled 24/7, split-second by split-second, by our brain/mind at below conscious, autonomic nervous system level. While alterations in heart muscle size & function (usual Doc focus) are also a factor, these are secondary

Heart failure

Interesting Fact

Heart failure with normal ejection fraction is present in ~50% of heart failure patients.

Yes


If you have a stethoscope you can hear your heart. Some patients with artificial valves (after a valve replacement) can hear their heart beat by the clicking of the valve. I can hear a person's mechanical heart valve from across a quiet examining room.

Murmurs that are NOT caused by an abnormality are common. They are called "functional murmurs", and are of no concern whatsoever.

This is true ONLY if the murmer comes from an anatomical defect or immaturity of the heart structure. Blood does make noise as it flows through the heart normally and if heard is an innocent murmer which is harmless.In addition, murmers can occur if the heart is damaged such as from an infection-rheumatic fever for example

A big majority of heart murmurs in children are innocent ones (without heart defect). True pathologic murmurs are associated with heart defects, often a part of birth defects.

a murmur is simply a audible sound in the heart caused by turbulence . its a physical sign not a diagnosis. some birth defects can cause murmurs and others wont. murmurs can be from restricted vales, leaky valves, communications between chambers, fevers,anemia etc. so if a pt has a murmur usually an echo of the heart is done with dopplers to further evaluate it .

High flow


Yes, this is common. Thyrotoxicosis increases cardiac output and the increased flow of blood can often create a "flow murmur". Although your doctor may want to do an echo to check it out, a flow murmur from hyperthyroidism is benign and usually goes away with treatment of the thyroid.

The majority of heart murmurs are "innocent", and they even develop as a result of becoming an accomplished athlete. Find the cause.

What could it mean to have two heart murmurs?

Answered by:
cardiographs Cardiac Heart Heart murmur

Murmurs


Murmurs are caused by turbulent blood flow. Having two murmurs suggests that two valves have flow problems or that one valve or orifice has a flow causing murmur across it in both systole and diastole.
