Preface to the 3rd edition

Thanks to the reader's response, we have published a third edition.
The revised edition includes all previous material, plus three additional chapters.
Additional findings include De Winter and Wellens signs, conduction block associated with myocardial infarction, and phase 4 block.
De Winter and Wellens electrocardiogram findings suggest critical coronary blood flow obstruction comparable to ST-segment elevation myocardial infarction.
Second, we added the conduction block electrocardiogram accompanying myocardial infarction.
Finally, the fourth phase block is a theory that explains paroxysmal atrioventricular block.
The format remains the same as before, in the form of questions and answers, and we have tried to make it easy to explain.
I sincerely hope that this book will spark interest in electrocardiography and contribute to improving readers' skills.

I would like to take this opportunity to express my gratitude to everyone who attends the electrocardiography training course every year.
