Webb4 feb. 2024 · 3. Poor R wave progression. Poor R wave progression is described with an R wave ≤ 3 mm inV3 and is caused by: Prior anteroseptal MI. LVH. Inaccurate lead placement. May be a normal variant. Note that absent R wave progression is characteristically seen in dextrocardia (see previous ECG). Webb14 apr. 2024 · PR interval is short. There is slurring of the initial part of QRS—the delta wave (marked ⇩). Leads V 1 to V 6 show positive R wave. (b) Electrocardiogram in posteroinferior myocardial infarction. PR interval is normal and there is no slurring of initial part of QRS. (Reproduced with permission from: Mittal SR. Pre-excitation.

Webb15 jan. 2007 · Although there is slight variability in the P-P interval, consistent with sinus arrhythmia — the remarkable finding is the change in the PR interval. Slurring of the initial portion of the QRS complex of beats #7 through 11 results in PR interval shortening. The picture becomes clearer with inspection of simultaneously recorded leads V4 ...
