應用包含200多例心動圖的完整病例，涵蓋20多種與心血管系統(tǒng)有關的疾病，以及疾病在心動圖上的表現(xiàn)和分析方法。此應用可將您的Mac電腦變成專業(yè)的心動圖分析工作站。 超聲心動圖，是一種心臟超聲波檢查，它使用標準的超聲波技術顯示心臟的二維圖片?，F(xiàn)在最新的超聲診斷系統(tǒng)采用三維實時成像。耗時大約15-20分鐘，甚至更長。 除了產(chǎn)生心血管系統(tǒng)的兩維圖像，超聲心動圖使用脈沖或者連續(xù)超聲波，能對任意位置的血液和心肌組織速度作出準確的測量。這樣可以檢測心臟瓣膜區(qū)域功能、左右側心臟不正常聯(lián)系、瓣膜返流、以及心臟輸出量的計算等。其他測量的參數(shù)包括心臟尺寸（管腔直徑和室間隔厚度）和E / A比值。 Turn your Mac to an Echocardiography Workstation, with over 200 real world echocardiography exams to review and learn. Get yourself ready before you do the job on real human's heart. Echocardiography, often referred to as a cardiac echo or simply an echo, is a sonogram of the heart. (It is not abbreviated as ECG, which lay persons often use as an abbreviation for an electrocardiogram.) Echocardiography uses standard two-dimensional, three-dimensional, and Doppler ultrasound to create images of the heart. Echocardiography has become routinely used in the diagnosis, management, and follow-up of patients with any suspected or known heart diseases. It is one of the most widely used diagnostic tests in cardiology. It can provide a wealth of helpful information, including the size and shape of the heart (internal chamber size quantification), pumping capacity, and the location and extent of any tissue damage. An Echocardiogram can also give physicians other estimates of heart function such as a calculation of the cardiac output, ejection fraction, and diastolic function (how well the heart relaxes). Echocardiography can help detect cardiomyopathies, such as hypertrophic cardiomyopathy, dilated cardiomyopathy, and many others. The use of Stress Echocardiography may also help determine whether any chest pain or associated symptoms are related to heart disease. The biggest advantage to echocardiography is that it is noninvasive (doesn't involve breaking the skin or entering body cavities) and has no known risks or side effects. Not only can an echocardiogram create ultrasound images of heart structures, but it can also produce accurate assessment of the blood flowing through the heart, using pulsed or continuous wave Doppler ultrasound. This allows assessment of both normal and abnormal blood flow through the heart. Color Doppler as well as spectral Doppler is used to visualize any abnormal communications between the left and right side of the heart, any leaking of blood through the valves (valvular regurgitation), and to estimate how well the valves open (or do not open in the case of valvular stenosis). Echocardiography was also the first ultrasound subspecialty to use intravenous contrast.
