Webb4 jan. 2024 · Fragmented QRS is defined as the presence of R’ wave or notching of R or S wave in the presence of narrow QRS. It indicates heterogeneous depolarization of the ventricular myocardium that can occur due to ischemia, fibrosis, or scar. It may also be a marker of coronary microvascular dysfunction. What is a notch in ECG? WebbThe study demonstrates that QRS notching or slurring is a moderately sensitive and a very specific marker of ischemic heart disease in selected patients when using the resting … WebbIt is possible to diagnose pathological Q-waves (because the initial part of the QRS is not affected by the RBBB). Acute ischemia (ST-T changes) may also be judged as usual, despite the bundle branch block. Note that acute cor pulmonale with RBBB may cause large Q-waves in V1–V3, II, III and/or aVF.
