1
An echocardiogram is an easy non-invasive study.
2
It usually lasts half an hour to 45 minutes and basically it's an ultrasound of the heart.
3
It provides imaging of the heart
4
and during an echocardiogram we can assess the heart function how well the heart functions
5
and we will give a so-called ejection fraction
6
which quantify this also looks at the valves looking at a valve function assessing for stenosis
7
which is blockages are in the valves or regurgitation
8
which would be leakage of about and also quantifies this as well as other things
9
that surround the heart can indirectly measure the pressure in the lungs can also look at the aorta
10
which is the big blood vessel that leaves the heart measuring the size
11
and ruling out an aneurysm echocardiogram is also used in stress echo
12
when we look at the heart function during stress and indirectly
13
assess for coronary artery disease meaning
14
if an area of the heart doesn't get enough blood during the stress will show up as weakening of
15
that area of the heart which would indirectly tell us that the patient does have significant cornering artithesis.

本课介绍
在本次课程中，学习者将重点练习与心脏超声波相关的英语词汇和表达方式。该视频介绍了一种名为心脏超声（Echocardiogram）的无创检查，这项检查通常用于评估心脏的功能、心瓣膜的状态和其他关键生理指标。通过观看视频，您将不仅有机会了解医疗领域的专业术语，还能够提升自己的英语口语能力，特别是与健康相关的表达。
重要词汇与短语
- 心脏超声 (Echocardiogram)
- 非侵入性 (non-invasive)
- 心脏功能 (heart function)
- 射血分数 (ejection fraction)
- 瓣膜功能 (valve function)
- 狭窄 (stenosis)
- 回流 (regurgitation)
- 压力测量 (pressure measurement)
练习技巧
在进行英语影子跟读时，建议您选择与视频配音相同的速度进行跟读。这段视频的语速适中，适合各级学习者。可以通过以下步骤来提高您的跟读效果：
- 先完整观看一次视频，了解整体内容和语调。
- 在第二遍时，暂停视频并尝试模仿每一句话的语音和语调，力求做到精准无误。
- 尽量使用声带跟随配音，注意口形和发音部位，这样您可以更好地掌握音节的发声方式。
- 注意视频中的关键词汇，结合上下文进行背诵，特别是那些与医疗有关的术语，如“心脏功能”和“射血分数”。
通过反复练习，您将能够提高自己的shadow speech能力，使日常对话和专业讨论中的英语更加流畅自如。使用此shadowspeak方法，您还可以轻松将所学知识应用到看YouTube学英语的过程中，让语言学习变得更加生动有趣。
什么是跟读法？
跟读法 (Shadowing) 是一种有科学依据的语言学习技巧，最初开发用于专业口译员的培训，并由多语言者Alexander Arguelles博士普及。这个方法简单而强大：您在听英语母语原声的同时立即大声重复——就像是一个延迟1-2秒紧跟说话者的影子。与被动听力或语法练习不同，跟读法强迫您的大脑和口腔肌肉同时处理并模仿真实的讲话模式。研究表明它能显着提高发音准确性，语调，节奏，连读，听力理解和口语流利度——使其成为雅思口语备考和真实英语交流最有效的方法之一。
