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…
Differential Diagnoses: poor R wave progression and attention to T wave abnormalities
A 55-year-old woman presents with substernal chest pressure radiating to the left upper extremity, dyspnea, and nausea. She has a past medical history of HTN, DM, HLD, and is a…
