Cardiovascular System Topics
Includes three animated series on the cardiac action potential, the cardiac cycle, and blood pressure regulation. Note from Dr. Fitzovich on the cardiac action potential tutorial: “Be careful about control of sarcoplasmic reticulum (SR) calcium release in cardiac cells because it is mediated by calcium influx, not depolarization of the SR. Also note that a ‘funny current’ due to a special sodium channel is responsible for the pacemaker function.”
ECG Quizzes within the ECG Learning Center
Created by Frank G. Yanowitz, Professor of Medicine at the University of Utah School of Medicine, this website includes a variety of quizzes on ECGs. Website also includes an ECG outline, an image index, an American College of Cardiology (ACC)/American Heart Association (AHA) clinical competence section, a long pdf outline, and a feedback form.
This Harvard Web site allows you to quiz yourself, search cases by diagnosis, and browse cases with diagnoses.
EKG 12 Lead Placement Activity
Place the twelve EKG leads in the correct locations.
EKG 5 Lead Placement Activity
Place the five EKG leads in the correct locations.
Electrocardiogram (ECG/EKG) Library
Provides examples of ECGs for numerous conditions.
Heart: Rhythm Disorders
Describes and animates the electrical events for normal sinus rhythm and atrial fibrillation.
Introduction to ECG Interpretation
University of Wisconsin Medical School’s primer provides an introduction to ECG interpretation; six clinical cases with questions; tutorials for axis, basic concepts, fascicular block, hypertrophy, infarct, rate, and rhythm; a summary of ECG interpretation, guidelines for ECG interpretation, and a form for feedback.
Practical Clinical Skills
Includes tutorials for heart sounds, lung sounds, EKGs, abdominal sounds, and blood pressure. Also includes cases for carotid artery bruit and pulmonary problem solving. Also includes short courses that provide auscultation training by repetition.
Shockwave animations – Hyper Hearts
Includes animations of heart circulation, an EKG, a graph of pressure readings and ventricular volume, and a graph of heart sounds. Also includes brief tutorials on atrial systole, isovolumetric contraction, rapid ejection, reduced ejection, isovolumetric relaxation, rapid ventricular filling, and diastasis.
