Unformatted text preview: 3. Relate depolarization/repolarization of the heart to the generation of the EKG. 4. Understand the underlying physics of the Einthoven triangle. III. Sample Problems: 1. What would happen if it were possible for the ventricular action potential to invade the atria via the A-V bundle? 2. How would an increase in extracellular calcium affect the heartrate? 3. What would probably have more dire consequences, a septal infarct or one in the lateral ventricular wall? 4. What would the absence of a P wave in the EKG indicate? file:///C|/WINWORD/COURSES/31107/Lec22-07.htm8/15/2007 10:24:08 AM...
