| Description |
Collection Description A collection of tools related to electrical conduction in the heart, the cardiac cycle and cardiac output. Describe how this collection was used. This collection contains a range of resources related to electrical conduction in the heart, the cardiac cycle and cardiac output. It starts with background information in the form of mini-lectures and animations on blood flow through the heart and determination of the ECG. The collection includes a manipulable model for factors that regulate cardiac output and an interactive animation showing the real-time relationship between ECG, cardiac cycle, and pressure-volume relationships. Finally, the collection contains an article on the effects of exercise on cardiac output. This collection was used throughout a unit on cardiovascular physiology in an upper-level Human Physiology course. The effects of exercise on the cardiovascular system in normal and pathological states as used to apply concepts of cardiac output. Describe who used this collection (classroom, laboratory, education level, etc). This collection is designed for undergraduate settings and is most appropriate for upper-level courses. It could also be adapted for use in lower-divisionl undergraduate courses and possibly high school courses. The collection would also be useful introductory material for graduate and professional level courses. Describe how this collection works. The animation “Cardiac Circulation “ was used within the first couple days of a unit in cardiovascular physiology to illustrate basic heart anatomy and flow of blood through the heart. “10 Minute ECG” tutorials were be assigned before a class on ECGs. The pdfs from this tutorial were used in class to construct ECGs and compare them to ECGs of students collected in lab the day before. In this class and the next, “Human Systems Explorer” was used in a discussion of electrical conduction in the heart and the cardiac cycle. This led naturally into discussion of pressure-volume relationships and cardiac output, at which point students used the “Pressure-Volume Computer Model” to further explore factors that regulate cardiac output. Finally, students examined how ECGs and cardiac output are affected by exercise through a group exam that used data from “Cardiovascular Response to Exercise”. The resource “Computers as Teachers...” provides evidence for the effectiveness of use of computer animations in understanding cardiovascular physiology. Please enter suggestions for colleagues. Isolated segments of this collection can easily be pulled from the group and applied to particular curricular aims. | |||

This collection contains nice resources, but it is a bit advanced for my community college Anatomy and Physiology students. I like the data in "Cardiovascular Response to Exercise". Otherwise I have used other resources that cover the same material in a more straight forward manner and in less time.

This should really help students to practice what they learn from books; doing is better to understand.
