Course Overview

Welcome to this course on 12 Lead Interpretation. This course will provide a brief review of the heart’s vessels and electrical system and how to use a 12-lead to identify an ST-segment elevation myocardial infarction (STEMI). Other areas of focus include inferior wall MI and STE, which mimic hyperkalemia. Whether you are new to ECG interpretation or seeking to enhance your existing skills, this course accommodates a diverse audience with the shared goal of mastering the art of 12-lead ECG analysis.

‍

Course Objectives

• Define the characteristics of an inferior wall myocardial infarction (MI).

• Develop the competency to identify and interpret normal ECG waveforms, recognizing deviations indicative of various cardiac condition.

• Attain proficiency in the analysis of 12-lead ECGs, comprehending the unique perspectives each lead offers and understanding their collective role in capturing a comprehensive view of cardiac activity.

• Demonstrate a thorough understanding of the fundamental anatomy and physiology of the heart.

• Review the components comprising the heart's conduction system.

• Explain the placement of 12-lead ECG electrodes, highlighting their capacity to provide a more detailed view of the conduction system compared to a basic 3-lead ECG.

• Describe the indications for the placement of right-sided precordial leads and posterior lead electrodes.

• Articulate a systematic approach to analyzing a 12-lead ECG, emphasizing its clinical significance.

• Demonstrate an understanding of the distinctive EKG patterns associated with right and left bundle branch blocks.

• Correlate axis deviations with specific cardiac conditions and grasp the clinical significance of abnormal axis findings.

• Explain the ECG characteristics associated with hyperkalemia.

• Elaborate on the three "I's" of a 12-lead ECG (ischemia, injury, and infarct) and elucidate how to identify them using a 12-lead ECG.
