QRS complex Definition & Meaning Merriam-Webster Medical

Any abnormality of conduction takes longer and causes "widened" QRS complexes. In bundle branch block, there can be an abnormal second upward deflection within the QRS complex. In this case, such a second upward deflection is referred to as R′ (pronounced "R prime"). This would be described as an RSR′ pattern. Ventricles contain more muscle mass than the atria. Therefore, the QRS complex is considerabl… WebOct 13, 2024 · Recall that the QRS complex on electrocardiogram depicts the time taken for the ventricles to contract. Causes.
