WebWires connect the electrodes to a computer, which translates the electrical activity in your heart into tracings on a monitor and/or special ECG graph paper. Your doctor will analyze the ECG to learn more about your heart’s rhythm and the overall condition of your heart. An ECG shows several types of “waves” of electrical signals. The refractory period of cardiac muscle is distinct from that of skeletal muscle. Nerves that innervate skeletal muscle have an extremely short refractory period after being subjected to an action potential (of the order of 1 ms). This can lead to sustained or tetanic contraction. In the heart, contractions must be spaced to maintain a rhythm. Unlike in muscle, repolarization occurs at a slow rate (100 ms). This prevents the heart from undergoing sustained contractions becaus…
