WebAug 30, 2024 · LAST UPDATED August 30, 2024. Poor R Wave Progression. The R wave is the first upward deflection after the P wave. It is part of the QRS complex and poor R wave progression can signal a problem. In a normal ECG, the S wave transitions to the R wave looking prominent. With poor R wave progression the transition comes later than it should. WebPOOR R WAVE PROGRESSION ( PRWP ): An R wave in lead V3 < 3 mm tall. • PRWP may indicate an anterior wall myocardial infarction, but can also be caused by a normal variant, bundle branch blocks, left and right ventricular hypertrophy and preexcitation ( Wolff Parkinson White ), and abnormal lead placement.
