Preface:

The 12-lead surface electrocardiogram (ECG) is the best technique to record the electrical activity of the heart and although it initially had a diagnostic value only, it has been demonstrated in recent years that it has very important clinical implications that are very useful for risk stratification as well as choosing the best management of different heart diseases. In this book we encompass all this new clinical knowledge of the ECG with the aim of producing a clear text that is easy to understand for clinicians and trainees. The first part is a review of the electrical activity of the heart, the history of electrocardiography, and its usefulness and limitations. In the second and third parts we discuss the origins of normal ECG patterns and the changes that various heart diseases produce in ECG morphology. This includes the ECG patterns produced by atrial abnormalities, ventricular enlargement, ventricular blocks, preexcitation, ischemia, and necrosis. In all these situations we identify the most important clinical implications derived from these diagnoses. With regard to normal and abnormal ECG patterns, we have attempted to reflect our conviction that ECG patterns should not be memorized, but rather understood in terms of how they are originated. The best way to demonstrate this is a deductive approach based on electrocardiographic–vectorcardiographic correlations. However, when we understand this correlation it is no longer necessary to record VCG loops in order to improve on the information given by the ECG curves. Part 4 deals with the ECG diagnosis of arrhythmias based on the changes produced by various arrhythmias in the surface ECG. A deductive approach is again the best way to diagnose arrhythmias. We briefly discuss the most important clinical implications of various arrhythmias. For further information, the reader should consult our book Clinical Arrhythmology (Wiley-Blackwell 2011), from which we have taken some of the ECG figures. Part 5 of the book deals with the clinical usefulness of electrocardiography. Here we explain the diagnostic value of different ECG alterations, the ECG changes in different heart diseases and situations, the ECG as a marker of poor prognosis, and finally the limitations of the surface ECG. We also provide an overview of other ECG techniques that we use to complement the diagnostic capacity of the 12-lead surface ECG. After this preface, we provide a list of recommended reading which will help the reader to better understand the concepts discussed here. This list includes the classical works that have greatly influenced me personally, in addition to more recent books that provide new knowledge in all aspects of electrocardiology. After each chapter there are also expanded references on the topics discussed.
