Electrocardiography Part I 9.01

Cardiac Electrophysiology
The Cardiac Conduction System
Detailed description of the properties and tissues of the cardiac conduction system (sinoatrial (SA) node, internodal tracts and Bachmann's bundle, atrioventricular (AV) node, bundle of His, right and left bundle branches, and the Purkinje fibers). Through graphics and computerized animation, the user is shown how the tissues of the cardiac conduction system initiate atrial and ventricular depolarization and repolarization.
Correlation Between The ECG Waveform and The Cardiac Cycle
Describes the electrical activity of the heart as the waveforms are inscribed on an ECG tracing. Through graphics and computerized animation, the user is shown how the heart's electrical activity inscribes certain characteristic waveforms on an ECG tracing.
