Expert Solution

Step 1

Electrical currents that may be measured at the skin's surface are created by action potentials that travel through the myocardium during the cardiac cycle. Small voltage changes brought on by action potentials in the heart muscle can be detected using electrodes put on the body's surface and connected to the proper recording equipment. An electrocardiogram is a compiled record of the cardiac action potentials (ECG or EKG). The heart's electrical activity is captured by the ECG.
