The EKG Guy’s Ultimate EKG Breakdown is designed for individuals with little to no knowledge of the electrocardiogram (EKG, ECG), as well as for more advanced interpreters. This 25+ hour comprehensive course includes over 150 short lectures that cover the most important ECG topics. It is perfect for students, residents, nurses, fellows, paramedics, and other medical professionals where ECG literacy is useful.

The basic concepts and fundamentals will provide a strong ECG foundation as you progress in your career. By the time you complete this lecture series, you will have as much knowledge as most entry-level resident physicians (and cardiology fellows!).

The Ultimate EKG Breakdown book includes complete text and colored images that accompany the 150+ online videos. I’ve highlighted 75 “High-Yield” lectures in the book for those of you that just want to focus on the “must knows”, which can be completed in just over 12 hours. You can now order the pocket-sized version that can be used for the course and convenient to have handy wherever you go (eg, clinic, hospital, teaching, etc).

Why This Resource Was Developed

After hosting dozens of ECG sessions for nurses, ECG techs, residents, medical and nursing students, and other medical providers, one thing was clear: medical professionals want better ECG learning options. ECG interpretation skills are critical for patient care, yet many providers feel unequipped to achieve even basic ECG proficiency. When I hosted an ECG education seminar, participants dramatically improved their ECG comprehension after only 5 hours of learning – proving even a small amount of time dedicated to learning ECGs can make a big difference! This resource helps medical providers improve their ability to make real-time medical decisions that will improve the quality and efficiency of patient care.

The Ultimate EKG Breakdown is designed to fill a universal gap in the currently available options. Existing ECG resources tend to be either extremely basic or very advanced, with minimal clinical applicability. The Ultimate EKG Breakdown is designed to provide the most efficient way to learn about ECGs – starting from the beginner level and gradually progressing to an advanced interpreter level, focusing on clinical relevance and educational efficiency. My goal is to make the most of your time, to give you practical educational tools, and to have a little fun while we’re at it. More importantly, my goal is to provide every possible resource to help learners understand ECGs in the most efficient, helpful, and comprehensive way in order to ultimately deliver better patient care. The Ultimate EKG Breakdown is a portion of that.

The EKG Guy's Story

Learning how to interpret EKGs was a struggle for me. I remember coming home to a stack of EKGs my father (an interventional cardiologist) had left for me to interpret. I had no idea where to start. I was lost. All I saw were squiggly lines.

I started reading all the introductory books (Dubin’s, Thaler’s, etc.) and any resource I could get my hands on. None of the resources really did it nor did they provide much clinical relevance. I found myself reading textbooks (Chou’s, Marriott’s, etc.) and the medical literature to close the gaps. Ultimately, this was a very inefficient process.

I decided to develop a curriculum for my fellow medical students. I created videos. For some reason, students asked for more. People from around the world asked for more. Eventually there were hundreds of videos. The EKG Guy community was created. And thanks to you, it has now grown to over 750,000 followers in less than 18 months to become the largest, fastest growing ECG community in the world! I soon realized that maybe I was not the only one that struggled to learn EKGs, or at least wanted a better option.

With all that said, it is clear that medical professionals want better ECG learning options and hopefully I’ve provided that. And, maybe I wasn’t the only one struggling after all. I truly hope no one ever struggles learning ECGs again.

I want to thank you for your ongoing support. It means a lot. Thank YOU for helping us transform ECG education to deliver better patient care!

Course Breakdown

Part I: The Basics

In part I of the course, we look at the basics of the electrocardiogram (ECG, EKG). We discuss the cardiac anatomy and circulation, electrical conduction system of the heart, electrodes and vectors, various aspects of the normal cardiac cycle, along with important concepts to be aware of when interpreting a 12-lead EKG.

Part II: Rhythms

In part II of the course, we look at various rhythms. This portion of the book is broken down into sinus, atrial, atrioventricular, and ventricular rhythms. These topics also include the pathophysiology, mechanism, ECG features, and clinical significance of each rhythm.

Part III: Chamber Enlargement

In part III of the course, we discuss various types of atrial and ventricular enlargement. These topics also include the pathophysiology, mechanism, diagnostic ECG features, and clinical significance of each.

Part IV: Conduction Defects

In part IV of the course, we look at various conduction defects – including, different atrioventricular and intraventricular conduction blocks. These topics also include the pathophysiology, mechanism, ECG features, and clinical significance of each.

Part V: Myocardial Ischemia & Infarction

In part V of the course, we look at myocardial ischemia and infarction. This section includes a basic overview of myocardial ischemia, why ECG findings come about in the setting of ischemia, what changes are considered significant, coronary vascular anatomy, how to localize different coronary artery occlusions and clinical significance, various conduction defects that can come about in setting of myocardial infarction, among other ECG findings in certain ischemic conditions.

Part VI: Drugs & Electrolytes

In part VI of the course, we look at the ECG findings seen in common electrolyte disorders and medications. This includes how certain medication work, their clinical importance, and the ECG changes at normal and toxic levels.

Part VII: Artifacts

In part VII of the course, we look at various artifacts, including different types of lead reversals and how to identify them on the ECG.

Part VIII: Inherited Arrhythmia Disorders

In part VIII of the course, we look at certain types of inherited arrhythmia disorders, including their pathophysiology, ECG findings, diagnostic features, and clinical significance.

Part IX: Miscellaneous

In part IX of the course, we look at a number of important clinical conditions and the ECG features that can be seen with each. The pathophysiology and clinical significance is also provided when appropriate.

Part X: Congenital Heart Disease

In part X of the course, we look at various congenital heart diseases. With each topic, we discuss the pathophysiology, ECG features, as well as the clinical significance and prognosis.
