Poor R-wave progression
Results:
Poor R Wave Progression (PRWP) DDx
Key Points PRWP is a pattern, not a diagnosis. Use clinical context and compare with prior ECGs before acting. Practical definition: R in V3 less than 3 mm or a…
R Wave Basics
Key Points Definition: The R wave is the first positive deflection of the QRS complex, reflecting early ventricular depolarization, predominantly of the left ventricle. Normal progression: Precordial R amplitude increases…
Avoiding Misdiagnosis Through Proper Lead Placement
A 40-year-old man with no known medical problems presents with concerns about his cardiac health after a friend recently had an MI. He has no symptoms of acute coronary syndrome…
Differential Diagnoses: poor R wave progression, prolonged QT intervals, and much more
A 53-year-old woman presents to the emergency department with shortness of breath. The following ECG is obtained:
