In this activity, you will use the EKG sensor to make a five-second graphical recording of your heart's electrical events. From this recording, you will be able to calculate your heart rate. Objective: Use the EKG sensor to graph your heart’s electrical activity. Calculate heart rate based on your EKG recording.

Activity stimulates the heart to contract more vigorously than it does when the body is at rest. The EKG (electrocardiogram) sensor measures cardiac electrical potential waveforms (voltages) produced by the heart as its chambers contract. The EKG is not a direct measure of heart muscle activity.

The electrical activity of the heart Cardiac contractions are not dependent upon a nerve supply. However, innervation by the parasympathetic (vagus) and sympathetic nerves does modify the basic cardiac rhythm. Thus the central nervous system can affect this rhythm.

A. Electrical activity of the heart. 1. List the specialized cardiac structures through which electrical signals spread during a heartbeat, in the order in which they are depolarized. 2. Underline the structure above where the spread of depolarization is slowed down the most. Why does this slow-down help the heart perform its function?
