WebMay 16, 2024 · INTRODUCTION The term early repolarization (ER), also known as "J waves" or "J-point elevation," has long been used to characterize a QRS-T variant on the electrocardiogram (ECG). Most literature defines ER as being present on the ECG when there is J-point elevation of ≥0.1 mV in two adjacent leads with either a slurred or notched … WebCMS Review for EKG Interpretation – TO BE COMPLETED PRIOR TO LECTURE Review your AMS notes on EKG and Brunner pp 696-702 to answer these questions. 1.
