Chapter 12, Problem 7PI
Summary Introduction
To determine: The way in which the timing of the waves in an idealized electrocardiogram would change by reducing the L-type Ca2+ current in AV (atrioventricular) node cells.
Introduction: An ECG (electrocardiogram) is the test that measures the heart’s electrical activity and shows whether or not the heart is working normally.

Your first task though is to convince yourself that is true. The best way to do that is to start close to home. Find something in your house that is a product obtained directly from an invertebrate or only due to an invertebrate’s actions. Describe the product, its function and utility, as well as any human manufactured alternatives. Be sure to highlight the advantages of obtaining this directly from nature. Keep in mind, a product can be something you use, wear, eat, or enjoy for its visual appeal.arrow_forward
