Overview The vertebrate heart is a muscular pump capable of functioning without influence from the nervous system. As you may have discovered last week, the frog heart can beat rhythmically and pump fluid for Ecg lab report even after removal from the body, as long as it is well oxygenated.
This independence from direct nervous control relies on two critical features of cardiac muscle: These features involve generating and conducting action potentials in specialized muscle cells, resulting in electrical currents following a complex path through the heart.
The electrocardiogram ECG, or EKG after the German electrokardiogram is a recording of these electrical signals from electrodes placed usually on the skin surface. A typical ECG uses multiple electrodes placed on the chest and limbs to "view" the electrical signals from up to 12 different perspectives.
We will focus on one of the most commonly used ECG leads to examine the major events in the cardiac cycle. This lab exercise consists of three sections focusing on different questions: Record a resting ECG. How do electrical signals on the trace correlate with events in the heart? What are the relative proportions of systole and diastole in the heartbeat?
How regular is the heart rhythm? Record an ECG on the same person during exercise. As heart rate increases, which components of the cardiac cycle are shortened? Does the relative proportion of systole and diastole change?
How does the ECG reveal abnormalities in heart function? Since we are unlikely to observe major abnormalities in our small and, we hope, healthy sample of the population, we'll provide case histories of people with unusual ECGs and ask you to analyze the differences and speculate on the possible causes.
Very clear explanation of electrical basis for ECG and outstanding animations comparing electrical recording to the spread of excitation in the heart.

The blood is returned from the lungs to the left atrium by the pulmonary veins. From this step the blood in the left atrium goes through the left VA.
