Preface:

The first edition of the Medical Physiology Textbook was written by Arthur C. Guyton almost 50 years ago. Unlike many major medical textbooks, which often have 20 or more authors, the first eight editions of the Medical Physiology Textbook were written entirely by Dr. Guyton with each new edition arriving on schedule for almost 40 years. Over the years, Dr. Guyton’s textbook was widely used around the world and translated into 13 languages. One of the main reasons for the book’s unprecedented success was its amazing ability to explain complex physiological principles in language easily understood by students. His main goal with each issue was to instruct students in physiology, not to impress his professional colleagues.

Arthur C. Guyton’s writing style always kept the tone of a teacher talking to his students. I had the privilege of working closely with Dr. Guyton for almost 30 years and the honor of helping him with the ninth and tenth editions. For the eleventh edition, I have the same goal as in previous editions: to explain, in language easily understood by students, how the different cells, tissues, and organs of the human body work together to sustain life. This task has been challenging and exciting because our growing knowledge of physiology continues to unravel new mysteries of bodily functions. Many new techniques have been developed for learning about molecular and cellular physiology. We can increasingly present the principles of physiology in the terminology of the physical and molecular sciences rather than simply in a series of separate and inexplicable biological phenomena. This change is welcome, but it also makes reviewing each chapter a must, grasp a need. In this edition, I have tried to maintain the same unified organization of the text that has been helpful to students in the past and to ensure that the book is comprehensive enough that students wish to use it in later life as a basis for their professional studies careers. I hope this textbook conveys the majesty of the human body and its many functions and encourages students to study physiology throughout their careers.

Physiology is the link between basic science and medicine. The great beauty of physiology is that it integrates the individual functions of all the different cells, tissues, and organs of the body into one functional whole, the human body. In fact, the human body is much more than the sum of its parts, and life is based on this total function, not just the function of individual parts of the body isolated from each other. This brings us to an important question: How do the separate organs and systems coordinate to keep the entire body functioning properly? Fortunately, our bodies are endowed with a vast network of feedback controls that strike the necessary balances without which we could not live. Physiologists call this high level of internal body control homeostasis. In disease states, functional balances are often seriously disturbed and homeostasis is impaired. And, when even a single disturbance reaches a limit, the whole body can no longer live. One of the objectives of this text, therefore, is to emphasize the effectiveness and beauty of the body’s homeostasis mechanisms, as well as to present their abnormal function in disease.

Fundamentals of Electrocardiography

When a cardiac impulse passes through the heart, an electrical current also spreads from the heart into the adjacent tissues surrounding the heart. A small portion of the current spreads all the way to the surface of the body. If electrodes are placed on the skin on opposite sides of the heart, electrical potentials generated by the current can be recorded; the recording is known as an electrocardiogram (ECG).

 A normal ECG for two beats

A normal ECG for two beats of the heart is shown in Figure 11-1.

Waveforms of The Normal Electrocardiogram

The normal ECG (see Figure 11-1) is composed of a P wave, a QRS complex, and a T wave. The QRS complex is often, but not always, three separate waves: the Q wave, the R wave, and the S wave. The P wave is caused by electrical potentials generated when the atria depolarize before an atrial contraction begins. The QRS complex is caused by potentials generated when the ventricles depolarize before contraction—that is, as the depolarization wave spreads through the ventricles. Therefore, both the P wave and the components of the QRS complex are depolarization waves. The T wave is caused by potentials generated as the ventricles recover from depolarization. This process normally occurs in ventricular muscle 0.25 to 0.35 seconds after depolarization. The T wave is known as a repolarization wave. Thus, the ECG is composed of both depolarization and repolarization waves. The principles of depolarization and repolarization are discussed in Chapter 5. The distinction between depolarization waves and repolarization waves is so important in electrocardiography that further clarification is necessary.

Cardiac Depolarization Waves Versus Repolarization Waves

Figure 11-2 shows a single cardiac muscle fiber in four stages of depolarization and repolarization, with the color red designating depolarization. During depolarization, the normal negative potential inside the fiber reverses and becomes slightly positive inside and negative outside.

In Figure 11-2A, depolarization, demonstrated by red positive charges inside and red negative charges outside, is traveling from left to right. The first half of the fiber has already depolarized while the remaining half is still polarized. Therefore, the left electrode on the outside of the fiber is in an area of negativity, and the right electrode is in an area of positivity, which causes the meter to record positively. To the right of the muscle fiber is shown a record of changes in potential between the two electrodes, as recorded by a highspeed recording meter. Note that when depolarization has reached the halfway mark in Figure 11-2A, the recording on the right has risen to a maximum positive value. In Figure 11-2B, depolarization has extended over the entire muscle fiber, and the recording to the right has returned to the zero baselines because both electrodes are now in areas of equal negativity. The completed wave is a depolarization wave because it results from the spread of depolarization along the muscle fiber membrane. Figure 11-2C shows halfway repolarization of the same muscle fiber, with positivity returning to the outside of the fiber. At this point, the left electrode is in an area of positivity, and the right electrode is in an area of negativity. This polarity is opposite to the polarity in Figure 11- 2A. Consequently, the recording, as shown to the right, becomes negative. In Figure 11-2D, the muscle fiber has completely repolarized, and both electrodes are now in areas of positivity so that no potential difference is recorded between them. Thus, in the recording on the right, the potential returns once more to zero. This completed negative wave is a repolarization wave because it results from the spread of repolarization along the muscle fiber membrane.
