EKG interpretation can feel overwhelming, with many basics to understand, like P waves, T waves, PR intervals, QRS complexes, QT/QTc intervals, and lead placement. This introductory course builds a solid foundation in EKG principles that makes EKG interpretation straightforward, using a clear nine-step approach that shows you where to look, when to look, and what to look for on an EKG.In this course, you'll learn to:

• Define and identify a P wave, QRS complex, and T wave so you can quickly recognize normal vs. abnormal patterns without second-guessing yourself.

• Define and discuss the normal duration of a PR interval, QRS complex, and QT/QTc interval so you can spot normal EKG readings in seconds and save yourself the embarrassment of asking a colleague to help you with a normal EKG.

• Establish a systematic process for interpreting any EKG. This will give you a reliable 5-minute routine that eliminates guesswork and builds your reputation as a confident, competent practitioner.

EKG 100 builds on what you learned in Anatomy of an EKG. It focuses on practicing foundational interpretation skills with simpler EKGs to build confidence, reinforce learning, and create a solid base for advanced EKGs.

After going through this course, you'll:

• Strengthen your step-by-step EKG interpretation process until it becomes second nature.
• Learn to identify sinus rhythm, bradycardia, tachycardia, and arrhythmia on an EKG, and discover variants of normal (avoiding unnecessary, expensive testing for your patients).

• Identify intraventricular conduction delays (IVCDs), helping you catch crucial patterns that may go unnoticed by others.

EKG 101 is an advanced course that builds on the Anatomy of an EKG and EKG 100. It covers identifying right bundle branch blocks, left ventricular hypertrophy, and ischemia patterns. Mastering these skills will help you order the proper tests for patients and spot conditions like hypertensive heart disease and aortic stenosis.

After going through this course, you'll be able to:

• Understand the shape and duration of P waves, including signs of left atrial enlargement, so you can catch early cardiac changes others might miss.

• Recognize incomplete and complete right bundle branch blocks. Most people think these are complex conduction patterns. After going through this course, it'll become clear as day.

• Spot ST-T wave abnormalities and ischemia patterns on an EKG so you can act quickly on potentially dangerous cardiac changes and save lives through early detection.

EKG 102 is an advanced course that builds on Anatomy of an EKG, EKG 100, and EKG 101. It covers identifying left anterior and posterior fascicular blocks, as well as incomplete and complete left bundle branch blocks.

After going through this course, you'll be able to:

• Spot left anterior and posterior fascicular blocks quickly. These are subtle patterns that many people miss. But not you, as soon as you complete this course.

• Understand the leftward axis and poor R wave progression clearly, even when they might confuse others.

• Recognize complete and incomplete left bundle branch blocks at a glance, even on a busy day when you are under pressure.

EKG 103 takes your EKG interpretation skills to the next level. I recommend you complete the Anatomy of an EKG, EKG 100, EKG 101, and EKG 102 before taking this course, which builds on previous sessions.  In this course, you'll focus on the two key criteria for spotting old heart attacks on EKGs.

After going through this course, you'll be able to:

• Spot p-mitrale easily, a key sign of left atrial enlargement that others might overlook, helping you stand out amongst your colleagues.

• Connect EKG findings with the cardiac anatomy of past myocardial infarctions, deepening your understanding and confidence in clinical decisions.

• Identify premature ventricular contractions (PVCs), distinguish them from regular beats, and assess their importance without wasting your patient's time by incorrectly referring them for no reason.

EKG 104 teaches you to interpret EKGs with rhythms that aren't purely sinus or may have sinus rhythm along with other rhythms. Beyond interpretation, you'll also learn possible interventions. I recommended that you complete Anatomy of an EKG, along with EKG 100, 101, 102, and 103, as a foundation for this course.

After going through this course, you'll be able to:

• Recognize and interpret junctional rhythms, ectopic rhythms, atrial fibrillation, atrial flutter, and paced rhythms, making complex arrhythmias easy to understand and confidently initiate management before possible referral.

• Differentiate between aberrant conduction and premature ventricular contractions (PVCs). Understanding the underlying pathophysiology of both may change your treatment decisions.

• Accurately calculate an atrial rate in atrial flutter, a skill that enhances your clinical decisions and earns respect from colleagues who may find it challenging.

• Understand the basics of pacemakers, defibrillators, and cardiac resynchronization therapy, building confidence in managing patients with these devices.
