Description from the website: The focus of this lab is on heritable diseases of the heart. You are cast here as a virtual intern to accompany a doctor examining three different patients. Each patient is examined using more than one diagnostic tool, and at each stage, the doctor will invite you to examine the patient yourself and ask for your opinion. There are 4 examinations in this virtual lab: auscultation, echocardiography, MRI, pedigree (for genetic disease). The first task is to diagnose patient A by performing the four examinations. Then, there are patient B and patient C, so you can practice what you've learned from patient A to the other patients, and get more familiar with auscultation, echocardiography, and pedigree. Reminders: 1. While taking the quiz, you can click "hint" to help you answer the question. After reading the hint, click the "Quiz" tab to come back to the quiz. 2. I experienced two suddenly shutdown of Safari (MAC OS) in this virtual lab. Fortunately, the program allows us to start from where we left.
