12-Lead ECG – Cynthia L. Webner & Karen M. Marzlin

You will gain the essential skills and in-depth knowledge for determining:

• Axis Deviation
• A Systematic Approach to the 12-lead ECG
• Bundle Branch Block Identification
• Myocardial Injury & Ischemia
• Arrhythmia Interpretation

Attend this comprehensive ECG seminar and take your ECG knowledge to the next level. Your speakers Cynthia Webner, DNP, RN, CCNS, CCRN-CMC, CHFN, and Karen Marzlin, DNP, RN, CCNS, CCRN-CMC, CHFN will focus on the direct application of ECG interpretation in clinical practice and case study analyses, with many opportunities to practice your 12-lead ECG assessment skills.

Cindy and Karen have developed innovative teaching methods that will improve your long-term retention of key concepts through engaged hands-on learning activities, such as the creation of a reference worksheet that includes visual reminders for rapid and accurate assessment. You will use these skills every day in your clinical practice.

• Reciprocal changes
• Evolutionary ST / T wave changes
• Pathological Q waves
• Interpretation in presence of BBB
• Specific types of myocardial infarction
• Anterior wall
• Lateral wall
• Inferior wall
• Posterior wall
• Right ventricular

Complex Arrhythmia Interpretation

• Mechanisms of tachyarrhythmias
• Evaluating wide complex tachycardias
• VT versus SVT with BBB aberrancy

OBJECTIVES

• Identify correct electrode placement required for accurate 12-lead ECG acquisition.
• Differentiate normal from abnormal patterns on each lead of the 12-lead ECG.
• Determine cardiac axis using lead I and aVF.
• Describe the 12-lead ECG features seen in atrial and ventricular hypertrophy.
• Contrast the features of right bundle branch block from the features of left bundle branch block.
• Recognize patterns of infarct, injury, and ischemia on the 12-lead.
• Utilize morphology in Lead V1 and V6 to differentiate ventricular tachycardia from SVT with aberrant conduction.
• Recognize long QT as a risk factor for Torsades de Pointes.
