ejection fraction
发音：英 [i?d?ek??n fr?k??n] 美 [i?d?ek??n fr?k??n]
英语范文：Ejection fraction is a measure of the efficiency of the heart. It indicates how much blood is pumped out with each beat of the heart. A higher ejection fraction means that the heart is working more effectively, while a lower ejection fraction may indicate heart failure or other heart conditions.
翻译：射血分数是衡量心脏效率的一个指标，它表示每次心跳射出的血液量。射血分数越高，心脏的工作效率越高；而射血分数越低，可能表明心力衰竭或其他心脏疾病。
ejection fraction的英语作文音标和基础释义：ejection fraction 指的是心脏射血的能力，即每次心跳将多少血液从心脏泵出。在心脏病学中，射血分数是一个重要的指标，因为它可以反映心脏的功能。如果射血分数较低，这可能意味着存在心力衰竭或其他心脏问题。因此，了解和监测自己的射血分数对于预防和治疗心脏病非常重要。
ejection fraction
Ejection fraction is a term used in cardiovascular medicine to describe the portion of blood ejected from the left ventricle of the heart into the aorta. It is a measure of how efficiently the heart is pumping blood.
In normal hearts, the ejection fraction is usually around 55-65%. However, in cases of heart failure, the ejection fraction may be reduced, indicating that the heart is not able to pump blood effectively. This can lead to symptoms such as shortness of breath, fatigue, and swelling of the legs and ankles.
If you are concerned about your ejection fraction, it is recommended that you consult your doctor for a proper diagnosis and treatment plan. Treatment options may include lifestyle changes, medication, or surgery.
In conclusion, ejection fraction is an important measure of heart function that can help us understand how well our hearts are working. Keeping our hearts healthy is essential for maintaining good overall health.
ejection fraction
Ejection fraction is a measure of the function of the heart. It represents the proportion of blood pumped out of the heart with each heartbeat. It is calculated by dividing the volume of blood pumped out by the heart with each beat by the volume of blood in the ventricles at the start of the heartbeat.
In normal hearts, the ejection fraction is usually between 50% and 70%. However, if the heart is weakened due to disease or other conditions, the ejection fraction may be reduced.
Ejection fraction is an important indicator of heart health and can help doctors determine the need for treatment and monitor the progress of treatment.
In this context, ejection fraction is a key factor that determines how effectively the heart can pump blood and maintain normal bodily functions. Therefore, maintaining a healthy lifestyle, such as eating a balanced diet, getting enough exercise, and avoiding smoking and excessive alcohol consumption, can help improve ejection fraction and overall heart health.
In conclusion, ejection fraction is an essential measure of heart function that can help doctors diagnose and monitor heart disease. By maintaining a healthy lifestyle, we can improve our ejection fraction and overall heart health.
