WebOct 11, 2024 · Widening of a QRS after a long-short coupling interval may occur because of aberrancy. The pause after the nonconducted P wave allows the LBB to recover from refractoriness, allowing LBB conduction to occur, leading to a narrow QRS. WebThe presence of P waves immediately before every QRS complex indicates sinus rhythm. If there are no P waves, note whether the QRS complexes are wide or narrow, regular or irregular. No P waves and irregular narrow QRS complexes This is the hallmark of atrial fibrillation (see Figure 7 ).

WebThe QRS may be small (or low voltage) in pericardial effusion, high BMI, emphysema, cardiomyopathy and cardiac amyloid. The QRS is tall in left ventricular hypertrophy (LVH) The criteria suggestive of LVH on the ECG is if the height of the R wave in V6 + the depth of the S wave in V1.
