Blaufuss Multimedia Heart Sounds and Cardiac Arrhythmias TutorialThis website allows visitors to see and hear extensive digital recordings of actual patients, with high-resolution animations, ECGs and explanatory text. The Heart Sounds Tutorial focuses on the four common valvar lesions in the left heart including aortic regurgitation, aortic stenosis, mitral regurgitation, and mitral stenosis. In this tutorial, you will be able to examine actual patients with these lesions. By moving a virtual stethoscope over the chest, you can listen to the heart at several listening locations, while at the same time, you will see a video of the patient's pulsations in the neck, precordium, or extremities. The findings are explained with text, as well as illustrated with phonocardiograms, hemodynamic data, and computer animations. An interactive quiz will test your ability to identify correctly the first and second heart sounds, extra sounds, diastolic and systolic murmurs in recordings of actual patients, using a computer animation of the carotid pulse for timing. The SVT Tutorial is an online program that uses computer animations to explain arrhythmia mechanisms and their associated electrocardiographic findings for the following examples including AV Node Reentry, AV Reentry, Atrial Tachycardia, Atrial Flutter, and Atrial Fibrillation.
